FB (GLYMA_10G221500V4) — Glycine max

Summary

GmFB (GLYMA_10G221500V4) on soybean chromosome 10 encodes a GIGANTEA-family protein, containing GIGANTEA_N, GIGANTEA_M and GIGANTEA_C domains, and is annotated with multiple molecular functions including DNA-binding transcription repressor activity, calcium-dependent protein serine/threonine phosphatase activity, blue light photoreceptor activity, and phosphatidylethanolamine binding. The gene is associated with rhythmic processes, photoentrainment of the circadian clock, carotenoid and xanthophyll metabolism, abscisic acid anabolism, and negative regulation of auxin metabolism. It is linked to numerous agronomic traits including photoperiod sensitivity, vegetative-to-reproductive phase transition, flower number, fruit number, seed coat color, carotenoid content, plant male sterility, viral disease response, and nitrogen sensitivity. Localisation evidence connects GmFB to the nuclear ubiquitin ligase complex, SCF complex, chloroplast envelope, and tonoplast.
