PAB — Beta vulgaris subsp. vulgaris

Summary

BvPAB (BVRB_008650) on sugar beet chromosome 0219.scaffold00588 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, stroma, mitochondria, and cytosol localisation, and is linked to photosynthetic electron transport in photosystem II, chloroplast proton-transporting ATP synthase complex assembly, proton motive force-driven ATP synthesis, ATP anabolism, secretion, carbohydrate metabolism, signal transduction, and gALL development. BvPAB is associated with light response, light intensity response, and chloroplast development traits, as well as phenotypes including photosynthesis efficiency, photoprotection, photophosphorylation, non-photochemical quenching, chloroplast development, light sensitivity, RNA editing, and photosynthetic ATP synthesis. Related genes in other species link the family to non-photoautotrophic pale green cotyledons and abnormal chloroplast structure.
