RNA Splicing of Modulates the Transition to Flowering.

Flowering is a critical stage of plant development and is closely correlated with seed production and crop yield. Flowering transition is regulated by complex genetic networks in response to endogenous and environmental signals. FLOWERING LOCUS C (FLC) is a central repressor in the flowering transition of . The regulation of expression is well studied at transcriptional and post-transcriptional levels. A subset of antisense transcripts from locus, collectively termed cold-induced long antisense intragenic RNAs (), repress expression under cold exposure. Recent studies have provided important insights into the alternative splicing of and sense transcripts in response to developmental and environmental cues. Herein, at the 20th anniversary of functional identification, we summarise new research advances in the alternative splicing of sense and antisense transcripts that regulates flowering.
