AP2 — Cicer arietinum

Summary

PsAP2, located on chickpea chromosome 5LG3, encodes a protein with AP2/ERF and aspartic peptidase domains, and is associated with DNA binding transcription factor activity, transcription cis-regulatory region binding, and endopeptidase activity. The gene is linked to regulation of floral organ abscission, seed development, starch biosynthesis, endosperm development, and the transition from vegetative to reproductive phase. It is associated with responses to cold, light intensity, jasmonic acid and gibberellin signaling, and cadmium. Associations include grain yield, stem fresh weight, leaf relative water content, net photosynthetic rate, protein content, seed coat color, flowering time, and plant male sterility. The gene is also linked to stomatal density, trichome patterning, seed mucilage defects, and biomass accumulation. Related genes in other species are associated with photoperiodic flowering, floral organ abscission, drought tolerance, and seed size.
