CNA — Phaseolus vulgaris
Summary
PvCNA (PHAVU_005G166900) on chromosome 5 of French bean encodes a protein containing MEKHLA, HD-Zip_III, START, and homeodomain domains, with DNA-binding transcription factor activity. The gene is associated with meristem initiation and maintenance, determination of dorsal identity and bilateral symmetry, adaxial/abaxial axis specification, leaf shaping and morphogenesis, phloem or xylem histogenesis, leaf vascular tissue pattern formation, and plant organ morphogenesis. It has been linked to disease tolerance, insect damage response, and shoot apical meristem development. Phenotypic associations include lignification, lignin deposition, xylem and vascular development, leaf phyllotaxis, shoot regeneration, adaxial-abaxial leaf polarity, and enlarged shoot meristems. The gene is also associated with induced systemic resistance, callose deposition, response to bacteria and insects, and indole glucosinolate and camalexin biosynthesis.
