Abstract excerpt

Plant floral transition is a major developmental switch regulated by an integrated network of pathways. Arabidopsis FLOWERING LOCUS K (FLK), a protein with three KH RNA-binding domains, operates in the autonomous flowering-promotive pathway by decreasing the transcript levels of the key flowering repressor FLOWERING LOCUS C (FLC). Here we report that PEPPER (PEP), an FLK paralog previously shown to affect...
