CYTME2 — Sorghum bicolor

Summary

SORBI_3003G292400 (SbCYTME2) on sorghum chromosome 3 encodes a malic enzyme with malate dehydrogenase (decarboxylating) (NADP+) and oxaloacetate decarboxylase activities, classified as EC 1.1.1.40. The gene is associated with C4 photosynthesis, malate metabolism and transport, and responses to salt, cadmium, auxin, and brassinosteroid signalling. It is linked to traits including photosynthetic rate, water use efficiency, drought tolerance, sugar content, respiration rate, and stomatal resistance. Phenotypic associations include aluminum tolerance, drought response, seed germination, root development, osmotic stress tolerance, and pathogen resistance. The encoded protein localises to multiple compartments including the cytosol, plastid, mitochondria, and plasmodesma. Studies of related genes in other species link the family to salt stress tolerance, primary metabolism, and growth.
