CPD — Phaseolus vulgaris

Summary

PHAVU_008G224600, designated PvCPD and also known as PvCYP90A1 or PvDWF3, encodes a cytochrome P450 family protein with steroid 22S-hydroxylase and fatty acid 2-hydroxylase activities, acting as a monooxygenase that binds iron and heme. In French bean (Phaseolus vulgaris) on chromosome 8, this gene is associated with brassinosteroid anabolism and homeostasis, sterol and cholesterol metabolism, and steroidogenesis. It is linked to responses to water, UV-B, and light stimuli, as well as to anther wall tapetum cell differentiation, petal and stamen development, pollen exine formation, leaf development, polar cell growth, and nitrogen fixation. The encoded protein localizes to the endoplasmic reticulum, membrane, mitochondria, and plasmalemma. Associations with drought tolerance and nitrogen content have been noted, and related genes in other species link the family to dwarfism, male sterility, cell elongation, photomorphogenesis, and flowering time.
