ICDH — Capsicum annuum

Summary

CaICDH (T459_21257) on pepper chromosome 8 encodes an isocitrate dehydrogenase with NADP and NAD isocitric dehydrogenase activity, belonging to the isocitrate dehydrogenase NADP domain family. The enzyme is associated with the TCA cycle, glyoxylate cycle, cellular respiration, NAD and NADP metabolism, isocitrate metabolism, protein oxidation, detoxification, and brassinosteroid-mediated signalling. It is linked to fruit ripening, microsporogenesis, cell growth and death, and defence response to bacteria. Associations include traits such as pungency, cytoplasmic male sterility, drought tolerance, photosynthetic rate, respiration rate, chlorophyll content, soluble protein and proline content, root length and morphology, and protein content. The protein localises to mitochondria, chloroplast thylakoid and stroma, plastid, cytosol, plasmalemma, apoplast, and plasmodesmata. Studies of related genes in other species connect the family to seed weight, starch content, and salt and oxidative stress responses.
