NAC4 — Cicer arietinum

Summary

NAC4 (AhNAC35) on chickpea chromosome 10 encodes a NAC-domain protein with DNA-binding, sequence-specific DNA-binding, protein homodimerization, transcription cis-regulatory region binding, DNA-binding transcription factor activity, transcription coactivator activity, phosphatase activity, cis-regulatory region sequence-specific DNA binding, protein phosphatase activity, protein binding, RNA polymerase II cis-regulatory region sequence-specific DNA binding, promoter-specific chromatin binding, ubiquitin ligase activity, and ubiquitin-protein transferase activity. It is associated with abscisic acid, ethylene, gibberellin, and jasmonate signaling pathways, as well as responses to salinity and drought stress. The gene is linked to regulation of endosperm development, leaf senescence, reproductive structure development, and root meristem development. Associations with agronomic traits include lateral root length and number, seed set, flowering time, plant size, leaf morphology, pollen fertility, disease tolerance, and nitrate sensitivity. The protein localizes to the nucleus, endoplasmic reticulum, cytoplasm, and mitochondria. Studies of related genes in other species connect this gene family to stress tolerance, hormone signaling, and developmental processes.
