CKR1 — Triticum aestivum

Summary

TRAESCS5B02G158500 (symbol CKR1, also known as EIN2) on bread wheat chromosome 5B encodes a protein with C2H4 receptor activity, histidine kinase activity, dual-specificity protein kinase activity, metal ion transmembrane transporter activity, and ethene binding, among other molecular functions. It belongs to the NRAMP family. The gene is associated with Fusarium head blight resistance and reduced deoxynivalenol contamination in wheat. It is linked to ethylene-mediated signaling, jasmonic acid/ethylene-dependent systemic resistance, seed dormancy, regulation of stem cell renewal, post-embryonic root development, and responses to carbon starvation, hormones, and hydrogen peroxide. The protein localizes to the ER membrane, plasmalemma, nucleus, and cytosol. Associations with grain number, seed yield, ear number, net photosynthetic rate, temperature stress responses, and root architecture traits have also been observed.
