FRIGIDA delays flowering in Arabidopsis via a cotranscriptional mechanism involving direct interaction with the nuclear cap-binding complex.

Plant physiology - 1 Jul 2009

Abstract excerpt

A major determinant of flowering time in natural Arabidopsis (Arabidopsis thaliana) variants is FRIGIDA (FRI). FRI up-regulates expression of the floral repressor FLOWERING LOCUS C (FLC), thereby conferring a vernalization requirement and a winter annual habit. FRI encodes a novel nuclear protein with no conserved domains except for two coiled-coil regions. A mutation in the large subunit of the nuclear...
