HPR — Cucumis sativus
Summary
CSA_7G012940, designated HPR (also HPR-A, CsHPR), encodes a glycerate dehydrogenase (EC 1.1.1.29) with hydroxypyruvate reductase and glyoxylate reductase activities. In cucumber (Cucumis sativus, chromosome 7), the gene is associated with photorespiration, the oxidative photosynthetic carbon pathway, the glyoxylate cycle, and cellular responses to light and drought. It has been linked to traits including net photosynthetic rate, water use efficiency, biomass yield, plant height, stem diameter, seedling vigor, and drought tolerance, as well as nitrate, protein, and starch content. The product localizes to mitochondria, cytosol, and apoplast. Studies of related genes in other species connect the family to seed dormancy, germination, and photorespiration phenotypes.
