Fruit Firmness (Stewart Dalton, Spring 2013)

-Softening occurs with enzymatic digestion of cell wall components such as pectin, cellulose and hamicellulose.
-Pectin decreases as blueberries ripen from green to to blue- degradation of the cell wall and middle lamella is directly responsible for the loss of firmness in ripening fruits.
-Fruit frimness is an important economic trait in blueberries for many reasons.
-Expansin protein family- necessary for softening process. Expression of expansin mRNA and protein is correlated with growth and/or cell wall disassembly (Dotto et al, 2005)
-pectate lyase gene expression causes softening in strawberries (Jimenez-Bermudez et al, 2002)
