FLA — Arabidopsis thaliana

Summary

AT4G00650, also known as FLA, FRIGIDA, FRI, or RSB7, encodes a Frigida family protein with DNA-binding transcription factor activity, RNA cap binding, and protein binding functions. This gene is associated with the upregulation of the vernalization response, regulation of vegetative phase change, shade avoidance, meristem development, and anthocyanin accumulation in response to UV light. It has been linked to numerous traits including days to flowering, floral organ size and development, stem branching and length, leaf area index, leaf elongation rate, yield, heterosis, seed viability, sulfur content, nitrate uptake, stomatal resistance, and quantum yield. The protein localizes to the nucleus, nucleolus, cytosol, cytoplasm, Golgi complex, mitochondria, and plant-type vacuole. Studies of related genes in other species connect the family to stem elongation, hypocotyl growth, and virus tolerance.
