ICDH — Triticum turgidum subsp. durum

Summary

TRITD3BV1G082910 (ICDH, TtICDH) on durum wheat chromosome 3B encodes an isocitrate dehydrogenase (NADP(+)), a member of the Isocitrate_DH_NADP family, and is annotated with EC 1.1.1.42. The gene is associated with NADPH regeneration, the TCA cycle, glyoxylate cycle, and isocitrate, NADP, and NAD metabolism. It is linked to brassinosteroid-mediated signalling, defence response to bacteria, and response to zinc. The protein localises to chloroplast thylakoid and stroma, mitochondria, plastid, cytosol, apoplast, and plasmodesma. Associations include proline content, salinity tolerance, photosynthetic rate, root morphology, redox homeostasis, histone methylation, and leaf hydraulic conductivity. Studies of related genes in other species link the family to drought tolerance, chlorophyll content, net photosynthetic rate, transpiration rate, stomatal resistance, oxidative stress response, and disease tolerance.
