FES1 — Phaseolus vulgaris

Summary

PHAVU_006G183400, designated PvFES1, encodes a CCCH-type zinc-finger protein with DNA and protein binding activity, including homodimerization and heterodimerization, and is located in the nucleus and nucleolus. In French bean, this gene is associated with the regulation of vegetative phase change, meristem development, the timing of the transition from vegetative to reproductive phase, photoperiodic flowering, and the upregulation of the vernalization response. It is also linked to polyamine metabolism, detoxification, homeostasis, and defence responses to fungi. Associations with agronomically important traits include flowering time, inflorescence number and morphology, shoot branching, leaf senescence, seed viability, drought tolerance, disease tolerance, transpiration rate, and relative growth rate. Studies of related genes in other species connect the family to gametophyte development, vernalization responsiveness, and dehydration tolerance, while in cucumber the family has been linked to tolerance to cucumber mosaic virus.
