BSF — Phaseolus vulgaris

Summary

PHAVU_007G084200, designated PvBSF on chromosome 7 of French bean (Phaseolus vulgaris), encodes an S1-domain and NA-bd_OB-fold protein with RNA folding chaperone, misfolded RNA binding, nucleic acid binding, mRNA binding, protein binding, and structural constituent of ribosome activities. The gene is associated with plastid translation, RNA stabilization, plastid organization, nonphotochemical quenching, positive regulation of translation, response to light stimulus, and NO storage. Its product localizes to the ribosome, RNP, chloroplast stroma, plastid, and mitochondria. PvBSF is associated with pale green phenotype, reduced plant size, impaired photosynthetic electron flow, and photosynthetic complex biogenesis. Related genes in other species link the family to chloroplast mRNA stability and translation, seedling lethality with disrupted thylakoid membranes, and traits including amino acid content and photochemical quenching.
