BZIP — Pisum sativum

Summary

PsBZIP (PSAT7G140160) on garden pea chromosome 7LG7 encodes a bZIP transcription factor of the GBF1 subfamily, possessing DNA-binding, transcription factor activity, and protein heterodimerization activity. It localizes to the nucleus and is associated with response to hormone, leaf formation and development, nitrogen fixation, nodulation, seed maturation, fruit development, inflorescence and flower development, and transcriptional regulation. The gene is associated with photosynthetic ability and rate, as well as organ identity. Related genes in other species link the family to a wide range of agronomic traits including forage yield, plant height, seed weight and size, germination rate, drought tolerance, salt response, chlorophyll content, root traits, and sensitivity to abscisic acid and acid stress.
