HPR3 — Brassica juncea

Summary

BJUA08G07800S (symbol HPR3, BjHPR3) on Indian mustard chromosome A08 encodes a protein with D-isomer_DH_NAD-bd and NAD(P)-bd_dom_sf domains. It exhibits (2R)-hydroxyphenylpyruvate reductase, glyoxylate reductase, hydroxypyruvate reductase, and D-lactate dehydrogenase activities. The gene is associated with photorespiratory flux, photorespiration, photochemical efficiency, and plant growth. It is associated with lipogenesis, fatty acid oxidation, fat cell differentiation, heat generation, angiogenesis, regeneration, and myelination. The encoded protein localizes to the cytosol. Studies of related genes in other species link the family to 4-hydroxyphenyllactic acid accumulation and impaired tyrosine conversion, as well as plant growth and development traits.
