ICDH — Triticum turgidum subsp. durum

Summary

TRITD2AV1G218250 (ICDH) on durum wheat chromosome 2A encodes an isocitrate dehydrogenase (NADP(+)), a member of the Isocitrate_DH_NADP family with NADP isocitric dehydrogenase activity (EC 1.1.1.42). The gene is associated with NADPH regeneration, the TCA cycle, glyoxylate cycle, and NAD(P) metabolism. It is linked to brassinosteroid-mediated signalling, defence response to bacteria, and response to zinc. The product localises to plastids, chloroplast thylakoid and stroma, mitochondria, cytosol, apoplast, and plasmodesmata. Associations with proline content, salinity tolerance, photosynthetic rate, and root morphology have been reported. Studies of related genes in other species connect the ICDH family to drought tolerance, leaf relative water content, net photosynthetic rate, chlorophyll content, and oxidative stress response.
