ZRZ — Cicer arietinum

Summary

CaZRZ (LOC101495941) on chickpea chromosome 2 encodes a MATE family protein with xenobiotic transmembrane transporter, iron channel, red/far-red light photoreceptor, histidine kinase, sequence-specific DNA binding, and protein homodimerization activities. It is associated with regulation of plant organ formation, xenobiotic detoxification, iron transport and homeostasis, nitrogen fixation, abscisic acid metabolism, circadian regulation of calcium oscillation, stomatal complex development, and responses to nematodes, light stimuli, and hydrogen peroxide. The gene is linked to numerous agronomic traits including yield, biomass, water use efficiency, transpiration rate, phosphorus uptake, leaf angle, photoperiod-sensitive flowering time, and biotic stress tolerance. It localizes to the nucleus, cytosol, plasma membrane, Golgi, and endosomes. Studies of related genes in other species connect the family to photomorphogenesis, circadian rhythm, flowering time, and starch synthesis.
