Figure 1. Transcriptomic profiling experiments comparing active vs dormant buds in Arabidopsis. (A) axillary bud dormancy was induced by an 8-hour treatment of low R:FR = 0.2. (B) bud activation was induced by decapitation of the main apex. Buds of intact or decapitated plants were pool-collected and transcriptional profiles compared after 24 h. (C) bud activation was induced by exposing plants grown in shade (R:FR = 0.08) to high R:FR = 3.5 for 3 hours. Bud n-2 (n being the uppermost rosette bud) was analyzed. Red, dormant buds. Green, active buds.
