MD1 — Capsicum annuum

Summary

CaMD1 (T459_07792) on pepper chromosome 3 encodes a malate dehydrogenase with NAD-L-malate dehydrogenase and L-malate dehydrogenase (NADP+) activities, and is also associated with disulphide bond formation, ubiquitin ligase substrate adaptor, and mRNA, ATP, and protein binding. The gene is linked to the TCA cycle, oxaloacetate, malate, and NAD metabolism, as well as responses to cold, freezing, cold acclimation, thirst, and zinc. It has been connected to fruit ripening, seed development, embryogenesis, brassinosteroid-mediated signalling, and cellular responses to potassium, nitrogen, and phosphate starvation. Associations include leaf length, growth, senescence, and size, root and pistil morphology, photosynthetic and respiration rates, drought tolerance, and low-temperature stress response. Studies of related genes in other species link the family to fruit sweetness, firmness, color, and weight, seed weight and viability, and plant height.
