dc.description.abstractFlowering plants undergo floral transitions from vegetative phase to reproductive phase in response to multiple endogenous and environmental signals. In Arabidopsis, SHORT VEGETATIVE PHASE (SVP) has been suggested as a central regulator of flowering time. Recent findings have indicated that SVP functions by interacting with FLC to control the transcription of two floral pathway integrators, SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 (SOC1) and FLOWERING LOCUS T (FT). In a search for novel target genes of SVP that mediate its function in flowering regulation, we identified that AtPIN1 was transcriptionally regulated by SVP and it promoted flowering under both long days and short days. AtPIN1 responds to both photoperiod and vernalization, and its function as a flowering promoter depending on the activity of SOC1 and AGL24 was revealed by genetic cross analysis. In addition, this interaction between AtPIN1 and SOC1/AGL24 occurred at post-transcriptional level. Our data suggest that, as an enzyme that catalyzes cis/trans conformation change, AtPIN1 may bind to SOC1 and AGL24 and facilitates their conformational change, leading to the accumulation of specific conformations of these two proteins to promote flowering.
