CAP2 — Cicer arietinum

Summary

AhCAP2, located on chickpea chromosome 15, encodes a protein containing an AP2/ERF domain and a GIL1-like domain. The gene is associated with DNA binding transcription factor activity, transcription cis-regulatory region binding, DNA binding, sequence-specific DNA binding, protein binding, and structural constituent of nuclear pore. It is linked to biological processes including defense response, regulation of defense response, innate immunity, ethylene-mediated signaling pathway, regulation of ethylene-mediated signaling pathway, response to red or far red light, negative gravitropism, vacuolar transport, lytic vacuole organization, protein-nucleus export, response to heat, response to stress, salinity response, response to thirst, upregulation of transcription, and DNA-dependent transcription. Localization evidence connects AhCAP2 to the nucleus, nuclear envelope, nuclear pore complex, plasma membrane, and late endosome membrane. The gene is associated with seed growth and development traits, as well as phenotypes related to defects in basal and R protein-mediated immunity, systemic acquired resistance, pathogen defense response, male and female gametophyte development, embryo viability, seed development, and immunity to Botrytis cinerea. Related genes in other species link the family to lytic vacuole biogenesis, gametogenesis, and delayed germination with fragmented root vacuoles.
