GAPB — Beta vulgaris subsp. vulgaris

Summary

BvGAPB (BVRB_1G014260) on sugar beet chromosome 1 encodes a protein with glyceraldehyde-3-phosphate dehydrogenase (NADP+) and (NAD+) phosphorylating activities, and is also annotated with histone acetyltransferase, kinase, and various binding functions. The gene is associated with the reductive pentose-phosphate cycle, plastid glycolysis, carbohydrate metabolism, pectin and glucose metabolism, melatonin anabolism, and autotrophy. It is linked to photosynthetic rate, quantum yield, chlorophyll content, starch content, stomatal complex closure time, bacterial blight disease resistance, disease tolerance, brassinosteroid sensitivity, and salt tolerance. Associations also include leaf vascular tissue pattern formation, response to sucrose, chitin and bacterial molecules, cell surface PRR signaling, RdDM, detoxification, and positive regulation of the hypersensitive response. The product localizes to the chloroplast stroma, thylakoid membrane, envelope, stromule, apoplast, plasmodesma, plasmalemma, and cytosol. Studies of related genes in other species link the family to chloroplast glyceraldehyde-3-phosphate dehydrogenase expression, defense responses, bacterial and fungal disease resistance, chitin-induced immune signaling, and thermotolerance.
