FB (GLYMA_16G163200V4) — Glycine max

Summary

GmFB (GLYMA_16G163200V4) on soybean chromosome 16 encodes a GIGANTEA-family protein characterized by GIGANTEA_N, GIGANTEA_M, and GIGANTEA_C domains. The gene product is associated with multiple molecular functions including DNA-binding transcription repressor activity, calcium-dependent protein serine/threonine phosphatase activity, blue light photoreceptor activity, and protein N-GlcNAc transferase activity. GmFB is associated with rhythmic processes, photoentrainment of the circadian clock, regulation of phytochrome signaling, and carotenoid and xanthophyll metabolism. It is linked to photoperiod sensitivity, vegetative-to-reproductive phase transition, stem length, leaf number, whole plant size, flower and fruit number, abscisic acid concentration, and responses to temperature stress, viral disease, and aphids. The gene is also associated with meristem determinacy, abscisic acid anabolism, and negative regulation of auxin metabolism.
