CKR1 — Pisum sativum

Summary

PsCKR1 (PSAT3G041280) on pea chromosome 3LG5 encodes a protein with EIN2 and NRAMP family domains, annotated with C2H4 receptor activity, histidine kinase activity, dual-specificity protein kinase activity, and iron channel activity. It is associated with ethylene signaling and detection, jasmonic acid/ethylene-dependent systemic resistance, cytokinin metabolism, cellular iron and manganese ion homeostasis and transport, hydrogen peroxide biosynthesis, and responses to carbon starvation, hormones, and fructose. The gene is linked to traits including seed yield, fruit ripening, leaf senescence, photosynthetic rate, stomatal resistance, root development, lateral root length, stem elongation, cell elongation, anthocyanin content, temperature stress responses, aphid and insect damage responses, herbicide sensitivity, and sulfur sensitivity. It localizes to the ER membrane, plasmalemma, nucleus, and cytosol. Studies of related genes in other species connect it to ethylene signal transduction, fruit ripening, iron acquisition, nitrogen metabolism, salinity tolerance, and disease resistance.
