SSR Guidelines: Ideally, I’d like my primer as close to the gene as possible. The further you get the more likely you are to have recombination between the marker and gene of interest. I also tend to prefer di and tri nucleotide repeats of lengths greater than 5 as these tend to be the most polymorphic among different lines. Total fragment length (Both primers plus sequence between them) is ideally above 100bp and less than 700bp. Smaller fragments are hard to score accurately and fragments longer than 700bps can’t be scored accurately on automated capillary sequencers due to the limits of the PCR reaction and the lane standards in fragment analysis kits.

We thought we might focus on the transposable element family called MITEs. Here is a are four papers to get us started. In the end, we decided this was not the best use of our time.

Therefore, we have decided to focus on the ESTs which we have not explored at all. Each member of the team is using his or her SSR genes to query the EST database. We can also use the SSR primers to find bigger portions of the scaffolds until we get a hit in the ESTs (if possible). Once we have EST hits, we will download the EST sequences and use those to BLAST against the genome assembly scaffolds again to see if we get more scaffold hits.

After that, we may consider self-infertility, but we'll see if we have time.

Finally, we will schedule a trip to DHMRI in Kannoplis to see the sequencers.

5' Cap - a methylated guanine nucleotide that is added to the 5' end of a mRNA molecule in eukaryotes. It is added by a 5' to 5' triphosphate linkage, and it gives the mRNA resistance to 5' exonucleases. [1] (Laura M.)

16S rRNA - ribosomal RNA found in the small subunit of prokaryotic ribosomes. rRNA functions in decoding mRNA and interacting with tRNAs in translation. Particularly 16S rRNA is a well-conserved gene found in all organisms (in prokaryotes and eukaryotic mitochondria) often used in comparative genomes when studying phylogeny (Lecture, Olivia)

454 Sequencing - 454 instruments are pyrosequencers that carry out many reactions at a time (parallel sequencing) in wells of a PicoTiter Plate. Beads coated with thousands of homogeneous DNA fragments are added to individual wells on the plate. The DNA fragments are amplified in an oil emulsion mixture with DNA polymerase and primers. dNTPs are sequentially added to the wells one at a time and washed. The process of continuous washing and the sequencial addition of dNTPs, DNA polymerase, luciferase, and ATP-sulfurylase explains the high reagent costs of sequencing. ATP-sulfurylase converts the PPi released from each dNTP addition to the complementary strand of the original ssDNA to ATP. ATP fuels luciferase in each well. The light produced is detected with a flourescence microscope. The current (2009) 454 FLX system has the ability to sequence 100 Mb DNA in 8 hours with an average read of 250 bp and raw accuracy of 99.5%. [2] [3] (Jared)

A

abscisic acid- a key regulator of fruit ripening in nonclimacteric fruit, such as blueberries [4] (Stewart Dalton)

accession number - a unique identifier given to DNA and protein sequences to allow for tracking of sequence information within a single database [5] (Will).

acid invertase- an enzyme essential to sucrose metabolism, specifically in fruit, that hydrolyzes sucrose into fructose and glucose. Low levels of acid invertase have been shown to be associated with high levels of intracellular sucrose, and hence, to regulate storage and breakdown of sugar (sucrose) in fruit.[6] (Lauren)

acyltransferases - Enzymes that catalyze the transfer of an acyl group from a donor (such as acetyl CoA) to an acceptor. Activity of these enzymes adds a great deal of diversity athnocyanins, flavonoids, and phenolic compounds in Vaccinum Corymbosum[7] (Puneet)

adaptors- short DNA sequences that can be attached to DNA fragments and used for amplification and sequencing [8] (Stewart Dalton)

adsorption - the accumulation of molecules on the surface of a material. This can be part of a lab procedure to purify and isolate a specific portion of a cell or a protein (Wikipedia, Olivia)

alien genes - genes found in a genome that appear to have been inserted into an organism's genome from another species, more than likely through horizontal gene transfer ([1] Campbell, Claudia)

alternative splicing - the process by which one gene can be translated into different protein isoforms. This is done by reconnecting the exons of the RNA produced in transcription in multiple ways during RNA splicing. ([9] Dylan)

allele frequency - Allele frequency is a measure of the relative frequency of an allele at a genetic locus in a population. Ex: .36 indicates that 36% of individuals have that allele, and 64% do not. [10](Erich)

allogeneic - variation in alleles among members of the same species. ([11] William G.)

aneuploidy - an individual has a different number of chromosomes than typically found in the wild type. For example, sex-chromosome aneuploidy in humans can result in the phenotypes of Turner syndrome (XO) or Klinefelter syndrome (XXY). Griffiths et al, 2000 (Austin)

ANOVA - Analysis of Variance is a statistical test that analyzes the effect of a particular variable on multiple groups of data. By analyzing the variance between the means of each group of data, ANOVA can determine if there is any statistically significant difference between any of the means. [12] [13] (Chadinha)

anthocyanidin - a naturally occurring sugar-free plant pigment and a member of the flavonoid family. Anthocyanidins result from the degradation of anthocyanins. pH level affects the color of anthocyanidins. A low pH results in colored anthocyanidins, while higher pH gives anthocyanidins that are without color. [14] [15] (Daniel)

anthocyanins - a member of the flavonoid family that changes color with pH, giving various fruits their coloration. The health benefits of anthocyanin are potentially great, with laboratory results suggesting positive effects against cancer, aging and neurological diseases, inflammation, diabetes, and bacterial infections. It is, however, poorly conserved during digestion and would have to be modified somehow for medicinal use. [16] [17] (Dylan)

antisense (RNA or DNA)-a piece of DNA or RNA that binds to a complementary sequence of DNA or RNA. These segments of genetic material can be used to identify the existence of a disease gene and they can also be used to bind to specific DNA or mRNA sequences to inhibit their function (5 Pallavi).

Apollo - Gene annotation software that allows you to visualize genes you have identified, your annotations for them, and where they lie within a genome Berkeley(Lexi).

Arabidopsis thaliana - the scientific name for the thale cress plant; it was the first plant to have its genome sequenced, and is a model organism for understanding plant biology and genetics (Wikipedia.org, Jay)

Archaea - one of the three evolutionary domains. A group of unicellular prokaryotes that were previously grouped with Bacteria, but have some genes and metabolic pathways more similar to eukaryotes, such as those involved in transcription and translation. Many Archaea are extremophiles, such as Halobacteria that thrive in high-salt environments (Lecture, Olivia)

Archaeal rhodopsins - Archaeal rhodopsins are light-sensitive and light-activated transmembrane proteins only found in archaeal plasma membranes. Bacteriorhodopsin (BR) and Halorhodopsin (HR) are both archaeal rhodopsins that are proton and chloride light drive pumps, respectively, indicating that the functionality of archaeal rhodopsins is diverse [18] (Katie)

assembly - the process of taking many short sequences of DNA, often from whole genome shotgun sequencing, and compiling overlapping regions to create a representation of the chromosomes from which the DNA originated. ([19] Mike)

auxins a type of plant hormone that promotes cell growth and helps determine the shape of a plant. Auxins can positively affect both the vertical formation of the stem and the lateral growth of roots. Auxins also mediate the growth of fruit and the release of seeds.([20] [21] , Daniel)

Avirulence genes - the parasitic counterpart to a resistance, or "R" gene of a host. R genes protect against the gene product of the avirulence, or Arv gene. ([22] TK)

B

BAC - bacterial articifical chromosome, a DNA construct used for transforming or cloning segments of DNA and often used to sequence the genetic code of organisms (Wikipedia.org, Jay)

Bacteriorhodopsin- A transmembrane archaeal rhodopsin protein that uses light energy to move protons across membranes, creating an electrochemical gradient that is converted into chemical energy [23] (Katie).

Bacterioruberin - Bacterioruberin is a “carotenoid pigment” found in some halophiles giving them a red color and providing assumed protection from strong sunlight [24]. The structure also plays a stabilizing role in the archaeal rhodopsin proteins [25] (Katie).

bioinformatics - the multi-disciplinary approach of using biology, computer science and mathematics to solve or better understand biological problems [26] (Matt)

bit score - a measurement of a sequence’s alignment, describing the likelihood that a sequence is a random match rather than an authentic homologue to a defined sequence in the database. The calculation of a bit score accounts for the presence of gaps and the number of alignments between the experimental and database sequences. McEntyre and Ostell, 2002 (Austin)

BLAST - (Basic Local Alignment Search Tool) finds regions of local similarity between sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches. [27] (Mary)

Blastula - is a hollow sphere of cells that transitions to the gastrula through a process of cell division known as clevage in the early stages of embryonic development. [28] (William G.)

BLASTx - a BLAST search (see BLAST) in which a nucleotide sequence is entered and translated by BLAST before comparing to a protein database. [29] (Aaron)

Bligh-Dyer method- A lipid extraction method that uses chloroform-methanol as a solvent but also includes a re-extraction of the sample, just with chloroform, before evaporation of the solvent to capture more non-polar lipids. [30] The lipid membrane of archaea is extremely unique not only in composition (see Isoprenoid lipids) but also in the archaeal rhodopsins that are scattered among the plasma membrane [31]. In order to study the uniqueness of archaeal membranes one needs to observe the lipids outside of the membrane, which the Bligh-Dyer method accomplishes (Katie)

bioinformatics - The science of managing and analyzing biological data using advanced computing techniques; bioinformatics is especially important in analyzing genomic research data. ([32] [33] Mike)

bioperl- a collection of Perl modules that facilitate the development of Perl scripts for bioinformatics applications such as accessing sequence data from local and remote databases, transforming formats of database, manipulating individual sequences, searching for similar sequences, searching for genes and other structures on genomic DNA, or developing a machine readable sequence annotations. [34] (Wikipedia, Max Win)

bootstrap value - common reliability test of a phylogenetic tree, calculated as a percentage. In generating a phylogenetic tree, the sequences will be resampled, or rerun, multiple times. If a pair of sequences are consistently grouped together for 100 out of 100 resamplings, then the certainty that those sequences are correctly grouped would be very high, and the bootstrap value would be 100. If a pair of samples were grouped together only 50 out of 100 resamplings, the certainty that those sequences are correctly grouped would be lower; the bootstrap value would be 50. On phylogenetic trees, these values may be placed adjacent to the group to which they refer. (Lecture, Olivia)

C

CAGE - Cap Analysis Gene Expression. A technique for identifying the start sites for transcription and determining the amount of promoter usage in eukaryotic genomes. Small fragments (20-21 nucleotides) from the beginnings of mRNAs are extracted, reverse-transcribed to DNA, PCR amplified, and sequenced. These sequences (called "tags") are compared against a known genome to identify exact transcription start sites. ([35] Dylan)

carbon fixation - using carbon dioxide to create organic materials [36] (Samantha)

CCCP - carbonyl cyanide m-chlorophenyl hydrazone; a nitrile ionophore that inhibits oxidative phosphorylation and photophosphorylation. Ionophores are lipid-soluble molecules allowing them to transfer across membranes, creating pores that disrupt transmembrane ion gradients. (Sugiyama 1994 article, Olivia)

cell division control (Cdc) protein - for example, Cdc6 found in Halorhabdus utahensis; protein responsible for activating and maintaining mechanisms of cell division. Cell division control proteins are important in annotation because the presence of a Cdc gene is a good indicator for finding the origin of replication in a circular chromosome. (Bakke et al 2009, Olivia)

CDD (Conserved Domains Database)- a database used to identify the conserved domains present in a protein query sequence [37] (Mary)

cDNA - DNA that is reverse-transcribed from mature mRNA. A cDNA library provides templates for genes that are expressed within an organism. [38]. (Pyfrom)

centimorgan (cM) - A unit of measure of genetic recombination frequency, and therefore genetic linkage. One centimorgan is equal to a 1% chance that a marker at one genetic locus will be separated from a marker at a second locus due to crossing over in a single generation. In human beings, one centimorgan is equivalent, on average, to about one million base pairs. ([39] [40] Mike)

chaperonin - a protein complex that assists some newly formed polypeptide chains by folding them into their final, functional, three-dimensional form [41] (Matt)

chemoorganotrophic - refers to organisms that obtain energy from oxidation/reduction reactions using organic electron donors (Link, Earthlife Claudia)

chemotaxis - the process in which cells will seek out or flee from a high concentration of certain chemicals and is found in both uni- and multicellular organisms. This process is used to avoid toxins or find food in unicelllular organisms or tasks such as reproduction in multicellular organisms [42] (Nick)

chemotaxonomy - the attempt to classify and identify organisms according to demonstrable differences and similarities in their biochemical compositions [43] (Mary)

chilling requirement - the minimum time period a fruit bearing plant must spend in cold weather in order to blossom, often expressed in chill hours, which are calculated from duration spent at certain temperatures. ([44] Mike)

chimeric genome - A genome that consists of a mixture of genes from distinct species Baliga et al., 2004 (Karen)

Chloroplast chromosome - circular DNA found in the photosynthesizing organelle (chloroplast) of plants instead of the cell nucleus where most genetic material is located. This genome codes mostly for redox proteins involved in electron transport in photosynthesis. ([45] Dylan)

Circos Plot - A circular representation of the genome(s) for one or more species. It illustrates the extent of gene duplication within the species and/or orthologous sequences between multiple species by connecting lines between regions of the chromosomes that share the same DNA. In many cases, Circos plots endow us with a "tangible" understanding of where gene duplication may have occurred. For example, in the figure below, the series of red lines that connect portions of chromosomes 17 and 18 show that those regions share the same DNA. On this particular plot, the dark blue coloring on certain areas of all chromosomes signifies the extent to which that genetic region is duplicated in other parts of the genome. (Berger et al, 2011 Image courtesy of Imperial College London, Shamita)

cladogram - A visual representation of relatedness among species that shows common ancestry via the formation of branch points on the tree. The species similarity is computationally determined, and based on the similarity of their DNA and/or RNA sequences. ([46],Image courtesy of Curtis Clark Shamita)

cloud computing - dividing data processes, and inputting parts of these processes into nodes to spread out heavy computational workloads among many computers or sections of computers running simultaneously. Cloud computing has become especially popular in the field of genomics. Assembly algorithms may take days to sort through terabytes of data for a genome with high coverage. One option for external cloud services is Amazon's Elastic Computing Cloud (EC2). A labratory could also build an internal cloud, linking all computers in the lab together. Ubuntu, an open source, linux-based operating system, now has cloud support. [47],[48] (Jared)

climacteric/non-climacteric fruit–Some plants are susceptible to the effects of ethylene because it can trigger the maturation of fruit, opening of flower buds, and shedding of leaves. Such plants are referred to as climacteric, because their respirations increase with a concomitant increase in ethylene. Examples include bananas, apples, apricots, and peaches. Other plants, however, exhibit a decrease in respiration rates at fruit maturation and do not respond to an endogenous release of ethylene. Some examples include blueberries, strawberries, and grapes—all referred to as non-climacteric fruit. ([49], Shamita)

ClustalW - A web-based or command line tool that performs multiple sequence alignments to determine evolutionary relationships between three or more sequences [50] (Will).

CNV - copy number variants are a type of genomic variation that results in a varying number of copies of a particular section of the genome, much like a VNTR. The difference between a CNV and a VNTR is the scope, a VNTR will have a varying number of repeats of segment A. A CNV would be a sequence that started with segments A, B, C but became A, A, B, C or A, B, B, C – where a particular segment of a larger segment is copied. [51] (Chadinha)

COG (Cluster of Orthologous Groups)- corresponds to a highly conserved domain and generally consists of either individual proteins or groups of paralogs (COG Pallavi)

comparative genomics - the study of relationships between genomes of different strains and species. Comparative genomics aims to define similarities and differences in structure and/or function of different proteins, RNAs and regulation between organisms (Wikipedia and Lecture, Olivia)

complex traits - traits that are controlled by two or more genes and can be affected by environmental factors; therefore, Mendellian genetics rules do not directly apply to these traits [52] (Mark A.)

compression block - a compression block is a segment of repetitive DNA that has been shortened by the software used in shotgun sequencing. SSRs and VNTRs are candidate areas for compression blocks forming. [53] (Chadinha)

concatemer - long continuous DNA molecule that contains the same DNA sequence repeated in series [54](Samantha)

concordance rate - given that one individual has a certain inherited trait, the probability that the second individual in a pair with the first will have that same trait; often the pair described is a set of twins [55] (Mark A.)

congenic - two strains of an organism that are nearly identical, varying only at a single locus (also called coisogenic) [56] (Megan)

consensus sequence - a nucleotide sequence that is common, though not necessarily identical, in different genes and in genes from different organisms that are associated with a particular function. [57] (Megan)

conserved genes - regions of similar or identical sequences within DNA or proteins across species. Sequence conservation generally implies that there is a conserved gene in that location. Highly conserved genes are oftentimes necessary for survival and, therefore, any mutations are eliminated through natural selection. ([58] Dylan)

conserved ortholog set (COS)- a group of genes between different species that throughout evolution are conserved in sequence and copy number. ([59], Catherine Doyle)

contigs (contiguous DNA)- overlapping DNA segments that as a collection from a longer and gapless segment of DNA. (Discovery Genomics, Proteomics and Bioinformatics [60], Max Win)

controlled vocabulary - a set of terms used to standardize the description of characteristics in organisms' genomes, as designated by the Gene Ontology (GO) project ([1] Campbell, Claudia)

coding capacity- is the percentage of RNA-coding DNA present in a given genome (Discovery Genomics, Proteomics and Bioinformatics [61], Catherine Doyle )

coverage - refers to the number of times, on average, any piece of DNA in a sequenced genome has been individually sequenced (Lecture, Jay)

CPAN (Comprehensive Perl Archive Network) - an archive of over 12,200 modules of software written in Perl, as well as documentation for it. It contains a module called CPAN (or CPAN.pm) which is used as an installer for Perl modules such as BioPerl [62](Will).

Cryptochrome - a class of blue-light sensitive flavoproteins found in plants and animals. In plants, these proteins regulate germination and light-dark cycles. ([63] TK)

Cytochrome P450 - a group of enzymes that catalyze the oxidation of organic substances. Plant cytochromes P450 are involved in several different reactions which lead to various hormones, fatty acid conjugates, and defensive compounds. Terpenoids are often substrates for plant CYPs. ([64], Daniel)

Cytogenetics-the study of normal and abnormal chromosomes. This involves studying the causes of chromosomal abnormalities and looking at the structure of chromosomes (7 Pallavi).

cytokinins - plant hormones that promote cell division in both plant shoots and roots. The levels of auxins and cytokinins are in a constant ratio in plants. This ratio is crucial for the proper formation of plants both laterally and vertically. Cytokinins are sometimes used by farmers to generate more crops. plants[65] [66], Daniel)

D

digenic phenotype - phenotype caused by two genes, not one. ([67], Leland)

Disease triangle - a concept applied to plant disease epidemiology that represents the necessity of a pathogen, host, and conducive environment for disease to occur. ([68] TK)

DCCD - dicyclohexylcarbodiimide; compound that acts as a proton ATPase inhibitor (Sugiyama 1994 article, Olivia)

de Bruijin graphs - graphic representations of groups of short letter strands (k-mers). Used in genomic assembly, the graphs consist of rectangles of short nucleotide sequences and their reverse complements. Sequences vertically protruding from these rectangles overlap and share these rectangle base sequences. Arcs connect nodes of linked overlapping sequences.

Zerbino and Birney (2008) developed Velvet, a set of algorithms designed to manipulate these graphs in order to assemble high coverage genomes consisting of short reads. [69] (Jared)

definition line (DEFLINE) - the first line of the FASTA format that starts with a “greater than” (>) symbol, followed by a description of the submitted sequence. McEntyre and Ostell, 2002 (Austin)

Each BAC fragment in the Golden Path is fragmented randomly into smaller pieces and each piece is cloned into a plasmid and sequenced on both strands. These sequences are aligned so that identical sequences are overlapping. These contiguous pieces are then assembled into finished sequence once each strand has been sequenced about 4 times to produce 8X coverage of high quality data [140]. (Pyfrom)

Illumina sequencing - Illumina instruments amplify DNA fragments in situ on a flow cell. Fragment colonies are dispersed on the flow cell at a low concentration at first, allowing for non-overlapping fragment colonies. Clusters are promoted by isothermal bridging amplification. The amplification increases the density of these colonies. Florescently labeled nucleotides are cyclically washed over the flow cell. These nucleotides are conjugated with reversible terminators so that the four nucleotide bases can be simultaneously incorporated base by base across the flow cell. Laser induced excitation of the cell allows imaging of the excited flourophores. The use of a flow cell and reversible terminator allows the Illumina Genome Analyzer to produce 600 Mb of DNA per day with only 36 bp reads. The tradeoff between pyrosequencing methods and the flow cell method is increased throughput for shorter reads. The raw accuracy of the Illumina genome analyzer is over 98.5%. Increased coverage is necessary when using sequencers with high raw error rates. [147] [148] (Jared)

Each well is given a small amount of one nucleotide type. If the nucleotide is added to the DNA, a proton is released as a natural byproduct. The change in pH is detected and recorded. If the nucleotide is repeated in the DNA sequence and multiple bases of the same nucleotide are added, the resulting change in pH is greater and recorded as a larger pH shift. Because each well is independently monitored, they can contain different strands of DNA. Thus, the parallel processing capabilities for this DNA sequencing method are massive. [154] (Aaron)
