RHS9 — Triticum turgidum subsp. durum

Summary

TRITD7BV1G127580, also known as RHS9 or Ppd-A, encodes a member of the MES/HNL protein family with an alpha/beta hydrolase fold. The enzyme exhibits pheophorbidase, MESA esterase, MEJA esterase, and MeIAA esterase activities, and is associated with chlorophyll a breakdown, salicylic acid and jasmonic acid metabolism, leaf senescence, and responses to cold and UV-B. It localizes to the apoplast, extracellular space, plasmalemma, cytoplasm, and nucleus. This gene is linked to days to heading, flowering time, anthesis time, grain yield, grain number, spike fertility, floret number per spike, and seed number per spike. Studies of related genes in other species connect the family to photoperiod response, heading date, disease resistance, and reactive oxygen species regulation.
