CPD — Phaseolus vulgaris

Summary

PHAVU_001G242200, symbol PvCPD (also known as CPD, DWF3, CYP90A1), encodes a cytochrome P450 family protein with steroid 22S-hydroxylase and fatty acid 2-hydroxylase activities, acting as a monooxygenase that binds heme and iron. In French bean (Phaseolus vulgaris, chromosome 1), this gene is associated with brassinosteroid anabolism and homeostasis, sterol and cholesterol metabolism, steroidogenesis, and responses to water, thirst, UV-B, and light stimulus. It is linked to anther wall tapetum cell differentiation, pollen exine formation, polar cell growth, leaf development, upregulation of flower development, and nitrogen fixation. The encoded protein localizes to the endoplasmic reticulum, membrane, mitochondria, and plasmalemma. Associations include drought tolerance, nitrogen content, pollen tube growth, and root elongation. Studies of related genes in other species connect the family to brassinosteroid biosynthesis, dwarfism, male sterility, cell elongation, flowering time, biomass yield, and plant height.
