NAC1 — Phaseolus vulgaris

Summary

PHAVU_008G001000, also known as PvNAC1 or PvNAC21, encodes a NAC-domain-containing protein that localises to the nucleus and binds sequence-specific DNA. In French bean (Phaseolus vulgaris) on chromosome 8, this gene is associated with abscisic acid homeostasis and signalling, leaf senescence, cell death, anther and pollen development, reproductive structure development, nitrogen fixation, and response to absence of light. It is also linked to regulation of DNA-templated transcription, post-embryonic development, and system development. Studies of related genes in other species connect the family to drought tolerance, stem strength, root number, lateral root number, protein content, and cytoplasmic male sterility, though these traits are not yet established for PvNAC1 itself.
