PAB — Beta vulgaris subsp. vulgaris

Summary

BvPAB (BVRB_9G224350) on sugar beet chromosome 9 encodes a protein containing PAB_N, PAB_middle and PAB_C domains and is annotated as an enzyme modulator with protein binding molecular function. The gene is associated with chloroplast thylakoid membrane, chloroplast envelope, mitochondria and cytosol localisation, and with biological processes including photosynthetic electron transport in photosystem II, proton motive force-driven ATP synthesis, chloroplast proton-transporting ATP synthase complex assembly, ATP anabolism, secretion, carbohydrate metabolism, signal transduction and gALL development. BvPAB is associated with traits including light response, light intensity response and chloroplast development, and with phenotypes such as photosynthesis efficiency, photoprotection, photophosphorylation, chloroplast development, non-photochemical quenching, light sensitivity, RNA editing and abnormal chloroplast structure. Related genes in other species link the family to photosynthetic ATP synthesis and non-photoautotrophic, pale green cotyledon phenotypes.
