BZIP — Phaseolus vulgaris

Summary

PvBZIP (PHAVU_011G042600) on chromosome 11 of French bean encodes a bZIP transcription factor of the GBF1 subfamily, with DNA binding, transcription cis-regulatory region binding, and protein heterodimerization activities. The product localizes to the nucleus and is associated with abscisic acid signaling, response to water, chlorophyll metabolism, leaf development, cell wall assembly, abscission, embryogenesis, histogenesis, immune response, cell death, and chromatin modeling. It is associated with photosynthetic rate and drought tolerance. Studies of related genes in other species link the family to traits including seed weight, seed size, seed dormancy, germination rate, plant height, flowering time, root length, lateral root number, shoot dry weight, forage yield, chlorophyll content, photosynthetic ability, cell membrane stability, proline and sugar content, and responses to drought, salt, acid, and abscisic acid.
