MD1 — Solanum lycopersicum

Summary

SlMD1 (MD1, also known as SlNDH1) on tomato chromosome 9 encodes a protein with L-malate dehydrogenase (NADP+) and NAD-L-malate dehydrogenase activity, belonging to the malate dehydrogenase family. The gene is associated with C4 photosynthesis, oxaloacetate metabolism, NAD metabolism and its regulation, and cell wall organization. It has been linked to numerous agronomic traits including fruit sweetness, fruit weight, fruit firmness, fruit color, seed weight, seed viability, plant dry weight, leaf size and length, stem diameter, petiole length, flower and petal color, pistil morphology, cadmium concentration, flavonoid and anthocyanin content, sugar and protein content, photosynthetic rate, quantum yield, water use efficiency, stomatal resistance, respiration rate, and responses to low temperature and cold stress. The encoded protein localizes to chloroplast stroma, plastids, ER, Golgi, vacuole, plasmodesmata, apoplast, and secretory vesicles.
