ABC1 — Phaseolus vulgaris

Summary

PHAVU_009G117301, designated PvABC1, encodes a sigma factor with sigma-70 RNA polymerase initiation factor domains, conferring sigma factor activity, DNA-directed RNA polymerase activity, and transcription cis-regulatory region binding. This gene is associated with tRNA metabolism, photosystem stoichiometry adjustment, regulation of RNA anabolism, cellular response to light stimulus, DNA-templated transcription initiation, detoxification, blue and red light responses, chloroplast organization, and regulation of DNA-templated transcription. It localizes to the sigma factor antagonist complex. PvABC1 is associated with root elongation, cotyledon expansion, hypocotyl elongation, leaf variegation, photomorphogenesis, chloroplast biogenesis, and plastid-encoded tRNA expression. Related genes in other species are linked to gene transcription, light response, shoot dry weight, manganese concentration, chlorophyll content, and protein content.
