Dormancy induction
Dormancy is an adaptation mechanism that is vital to the survival of plants. Plant dormancy is induced by hormones such as abscisic acid. While it has many uses, abscisic acid inhibits fruit ripening, inhibits cell growth/seed germination, and downregulates enzymes needed for photosynthesis.

"It is clear from the results that glucose delays germination by activating the ABA signalling pathway via ABI3 and repressing the GA signalling pathway via SPY and RGL2. It has been shown that glucose application has a pronounced effect on ABI3 and RGL2, up-regulating both at the transcriptional level."

Gene expression during the induction, maintenance, and release of dormancy in apical buds of poplar . From this paper: "Three regulatory genes, AP2/EREBP, ERF4, and WRKY11, and one expressed protein gene were associated with this crucial step in dormancy induction (Fig. 7). Based on the function of the respective Arabidopsis homologues, the three regulatory genes could act downstream of ethylene and/or abscisic acid (ABA) signals during dormancy induction." [7]
