WOL — Arabidopsis thaliana

Summary

AT2G01830 (WOL, also known as CRE1, AHK4) encodes a transmembrane histidine kinase cytokinin receptor with histidine phosphotransfer kinase activity, classified as EC 2.7.13.3. This Arabidopsis thaliana gene on chromosome 2 is associated with cytokinin perception and sensing, phosphate starvation response, seed germination, vasculogenesis, protoxylem development, embryonic root morphogenesis, and regulation of chlorophyll catabolic processes. It has been linked to numerous traits including vascular tissue morphology, seed yield, shoot fresh weight, leaf length, stem length and diameter, root mass density, water use efficiency, floral organ size and development, callus induction, cell elongation, and responses to far-red and red light, auxin, ethylene, and sucrose. The protein localizes to the plasma membrane, endoplasmic reticulum, cytosol, nucleus, plastid, and stress granules. Studies of related genes in other species connect the family to stomatal immunity and phosphorelay signaling.
