Abstract Flowering regulation is a very important process in plant growth and development. Arabidopsis
molecular genetics analysis showed that MADS-box transcription factor FLC，RNA binding
protein（ FCA，FPA and FLK） and mRNA 3′ end processing factor（ FY） are all involved in this process.
The flowering factor urges plant to bloom by inhibiting FLC expression．Through post-transcriptional
regulation，RNA binding protein regulates the process of Arabidopsis flowering by regulating FLC
expression．Besides，microRNAs also participate in this process．This paper summarize d the regulating
process of these related factors to explain the mechanism of RNA processing factor in participating Arabidopsis
flowering regulation.
