FL1 — Beta vulgaris subsp. vulgaris

Summary

BVRB_6G150530 (FL1) on sugar beet chromosome 6 encodes a MADS-box transcription factor with DNA-binding, transcription coactivator, and protein dimerization activities, and is associated with mRNA regulatory element binding translation repressor activity, 3'-5' exoribonuclease activity, and SUMO transferase activity. The gene is associated with regulation of vernalization response, floral whorl development, stamen formation, seed growth, short-day photoperiodism, nitrate assimilation, salicylic acid metabolism, and siRNA processing. It localizes to the nucleus, nucleolus, plasmalemma, and mediator complex. FL1 is associated with traits including days to flowering, photoperiod-sensitive flowering time, flower and inflorescence morphology, seed protein content, leaf size and chlorosis, water use efficiency, anthocyanin content, root oxidative activity, and responses to aluminum, copper, phosphorus, high temperature, and abiotic stress. Related genes in other species are linked to flowering time, vernalization response, and thermosensitivity.
