FCA — Arabidopsis thaliana

Summary

AT4G16280 (FCA) in Arabidopsis thaliana encodes a protein with RNA-binding RRM domains, a WW domain, and histone methylase activity (H3K36 and H3K4). It is associated with posttranscriptional regulation of gene expression, mRNA 3'-end processing, chromatin silencing, regulation of thermomorphogenesis, regulation of auxin biosynthetic process, regulation of plant organ morphogenesis, carotenoid metabolism, response to nitrate starvation, and regulation of programmed cell death. The protein localises to the nucleus, cytoplasm, chromatin, and the SWI-SNF and Cul4-RING E3 ubiquitin ligase complexes. Associations with traits include flowering time, photoperiod sensitivity, drought recovery, seed longevity, root development, leaf area, stamen number, fruit set, inflorescence length, and responses to salt, temperature, nitrate, and cadmium. Related genes in other species are linked to embryo viability.
