In this paper, we report the characterization of several mutations in ABSCISIC ACID HYPERSENSITIVE 1 (ABHI) that suppress the high levels of FLC expression typically found in a FRI-containing, winter-annual genetic background. In order to isolate positive regilators of FLC, a screen for suppressors of the late-flowering behavior of a FRI/FLC- containing line was performed.  aArabidopsis thaliana  aCaracterização  aFlorescimento  aFlowering locus C  aFrigida  aSupressor  aTransição floral
