HPR — Brassica oleracea var. botrytis

Summary

BoHPR, located on chromosome 6 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with hydroxypyruvate reductase [NAD(P)H] activity, also annotated as (2R)-hydroxyphenylpyruvate reductase and glycerate dehydrogenase (NAD+). The product belongs to the D-isomer dehydrogenase NAD-binding domain and NAD(P)-binding domain superfamily. BoHPR is associated with the oxidative photosynthetic carbon pathway, cellular response to light stimulus, and cellular response to drought. It has been linked to localisation in the apoplast, mitochondria, cytosol, and chloroplast. Related genes in other species connect the family to photorespiration, seed germination, and sucrose-dependent germination with photorespiration defects, as well as to seed dormancy, seed growth and development, and drought tolerance.
