CMPG1 — Cicer arietinum

Summary

LOC101497632 (CMPG1) on chickpea chromosome 6 encodes a U-box domain-containing protein with ubiquitin ligase activity and GTPase activity, belonging to the PUB22/23/24-like family. The gene is associated with the regulation of brassinosteroid-mediated signaling, jasmonic acid signaling, and the downregulation of programmed cell death and defense responses. It has been linked to responses to ozone, bacterial and fungal symbionts, arbuscular mycorrhizae formation, and the endoplasmic reticulum unfolded protein response. Associations with agronomic traits include seed yield, lateral root number, root thickness, stomatal resistance, and responses to high temperature, oxidative stress, and salinity. The encoded protein localizes to the cytoplasm, nucleus, plasma membrane, and endoplasmic reticulum, and is part of heterotrimeric G-protein and Cul4-RING E3 ubiquitin ligase complexes. Related genes in other species are linked to drought tolerance, root architecture, and resistance to fungal pathogens.
