GAPB — Daucus carota subsp. sativus
Summary
DCAR_013933 (GAPB, DcGAPB) on carrot chromosome 4 encodes a glyceraldehyde-3-phosphate dehydrogenase (NADP⁺/NAD⁺) (EC 1.2.1.13) with a GlycerAld_3-P_DH_cat domain, localised to the chloroplast stroma, thylakoid membrane, and envelope. The gene is associated with the reductive pentose-phosphate cycle, plastid glycolysis, and glucose metabolism. It has been linked to photosynthetic rate, photosynthetic efficiency, stomatal closure, and responses to sucrose and osmotic stress. Associations also include bacterial blight disease resistance, disease tolerance, salinity tolerance, and chitin-induced immune responses. The gene is connected to brassinosteroid sensitivity and signaling, lateral root development, leaf vascular tissue pattern formation, and DNA methylation/demethylation. Studies of related genes in other species link the family to chloroplast glyceraldehyde-3-phosphate dehydrogenase expression, bacterial and fungal disease resistance, defense responses, and thermotolerance.
