MDAR5 — Solanum lycopersicum

Summary

SOLYC08G081530.3, designated MDAR5 (also SlMDHAR) on tomato chromosome 8, encodes a monodehydroascorbate reductase, an FAD/NAD-binding oxidoreductase with leghemoglobin reductase and dihydrolipoyl dehydrogenase activities. The gene is associated with the ascorbate-glutathione cycle, xanthophyll cycle, oxygen and nitrogen metabolism, and protein oxidation. It has been linked to numerous agronomic traits including fruit yield, fruit weight, firmness, color, shape, and lycopene, carotenoid, flavonoid, starch, and carbohydrate content. Associations also extend to ascorbic acid content, chilling tolerance, plant growth, and yield. Localisation evidence connects the product to mitochondria, peroxisome membrane, and cytoplasm. Related genes in other species are linked to salt stress tolerance.
