CPD — Arabidopsis thaliana

Summary

AT5G05690 (CPD, also known as DWARF 3 or CYP90A1) in Arabidopsis thaliana encodes a cytochrome P450 monooxygenase that acts as a C-23 hydroxylase and 3-dehydrogenase in brassinosteroid biosynthesis. The CPD protein is associated with brassinosteroid anabolism and homeostasis, steroidogenesis, and sterol anabolism. It is linked to plant height, leaf growth, root elongation, cell elongation and expansion, lateral root length, biomass yield, flowering time, and male sterility. The gene is also associated with secondary growth, vascular cell division, anther wall tapetum cell differentiation, pollen exine formation, and pollen tube growth. Additional associations include UV-B stress response, DNA damage repair, de-etiolation, and transdifferentiation. The protein localizes to membranes and mitochondria and is linked to water transport, electron transfer, and the TCA cycle.
