EST — Phaseolus vulgaris

Summary

PvEST (PHAVU_004G123800) on French bean chromosome 4 encodes a protein with carboxylesterase activity, gibberellin-binding capacity, and 4-hydroxyphenylacetate decarboxylase, isomerase, lyase, and hydrolase activities, belonging to the AB hydrolase fold and carboxylest/Gibb_receptor families. The gene is associated with strigolactone metabolism, floral organ morphogenesis, indole alkaloid metabolism, gibberellic acid signaling, defense response, and alkaloid anabolism. It localizes to the cytosol, cytoplasm, and nucleus. PvEST is linked to seed coat color, seed weight, and seed size. Studies of related genes in other species connect the family to drought tolerance, silk growth, senescence, plant height, anthesis-silking interval, branching, tillering, and leaf senescence, while sequence similarity links extend to shoot axis branching and stem senescence.
