GAPB — Capsicum annuum

Summary

CaGAPB (T459_35041) on pepper chromosome PGAv.1.6.scaffold2106 encodes a glyceraldehyde-3-phosphate dehydrogenase with NADP+ and NAD+ phosphorylating activities, and is also annotated with histone acetyltransferase and kinase activities. The gene is associated with the reductive pentose-phosphate cycle, ascorbate glutathione cycle, glucose metabolism, TCA cycle, autophagy, and photomorphogenesis. It is linked to photosynthetic rate, chlorophyll fluorescence, bacterial blight disease resistance, disease tolerance, osmotic stress tolerance, salinity tolerance, stomatal closure, and brassinosteroid sensitivity. The product localises to the chloroplast stroma, thylakoid membrane, envelope, stromule, apoplast, plasmodesma, and cytosol. Studies of related genes in other species link the family to chloroplast glyceraldehyde-3-phosphate dehydrogenase expression, defense response, and thermotolerance.
