HSD1 — Phaseolus vulgaris

Summary

PHAVU_009G084200, designated PvHSD1 on French bean chromosome 9, encodes a 3-beta-hydroxysteroid dehydrogenase (NAD+)/C4-decarboxylase, a member of the 3Beta_OHSteriod_DH/Estase family with a reticulon domain and NAD(P)-binding domain. The gene is associated with response to aldosterone and plant organ development, and its product localises to the endoplasmic reticulum and membrane. PvHSD1 has been linked to inflorescence internode elongation, leaf morphology, gravitropism, auxin transport, and stem length. Related genes in other species are linked to inflorescence length and leaf morphology.
