AFP-CA — Cicer arietinum

Summary

AFP-CA (AFP) on chickpea chromosome 1 encodes a protein with defensin, knottin, and expansion-like domains, and is annotated with cis-trans proline isomerase, GTPase, P-type calcium transporter, abscisic aldehyde oxidase, and RNA-binding activities. The gene is associated with cell wall loosening and organization, regulation of jasmonic acid biosynthesis and signaling, antiviral response, and herbicide response. It localizes to the extracellular region, membrane, nucleus, and protein storage vacuole membrane. AFP-CA is linked to traits including flowering time, root volume and thickness, photosynthetic rate, disease tolerance, high temperature stress response, oxidative stress response, and cell elongation. It also connects to pathways involving JAZ/MYC/NINJA/TPL/HDA19-mediated hormone signaling. Studies of related genes in other species link the family to CONSTANS protein stability, desiccation tolerance, and high-temperature-induced secondary seed dormancy.
