Abstract SHORT VEGETATIVE PHASE（SVP）encoded MADS-box protein is a repressor of
bolting and flowering in Cruciferous plants．SVP is mainly expressed in vegetative growth stage，which
is regulated by some flowering pathways，such as autonomous pathway．It can control flowering time by
regulating several floral signal integrators，such as FLOWERING LOCUS T（FT）and SUPPRESSOR
OF OVEREXPRESSION OF CONSTANS 1（SOC1）．This paper summarizes the effect mechanism of
SVP gene regulation on bolting and flowering．It also discusses about the prospects of future research
activities，according to present research status on SVP gene.
