HPR3 — Brassica juncea

Summary

BJUB04G11110S (BjHPR3) on Indian mustard chromosome B04 encodes a protein with hydroxypyruvate reductase, formate dehydrogenase, and glyoxylate reductase activities, and contains a D-isomer 2-hydroxyacid dehydrogenase catalytic domain. The gene is associated with the oxidative photosynthetic carbon pathway, formate breakdown, and mitochondrial and cytosolic localisation. Associations with photorespiratory flux, photochemical efficiency, and plant growth have been recorded. Studies of related genes in other species link the family to 4-hydroxyphenyllactic acid accumulation and impaired tyrosine conversion.
