HPR3 — Brassica juncea

Summary

BJUA09G05320S (HPR3, BjHPR3) on Indian mustard chromosome A09 encodes a protein with a D-isomer 2-hydroxyacid dehydrogenase catalytic domain and 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 also associated with lipogenesis, fatty acid oxidation, fat cell differentiation, heat generation, angiogenesis, myelination, and regeneration, and the product 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 to plant growth and development traits.
