PRR2 — Cucumis sativus

Summary

CsPRR2 (CSA_3G904140) on cucumber chromosome 3 encodes a GLK1/2-like protein with a Myb DNA-binding domain and a CheY-like receiver domain, possessing phosphorelay response regulator activity and sequence-specific DNA binding. The gene is associated with chlorophyll metabolism, pigmentation, circadian rhythm, cytokinin signaling, calcium signaling, and sulfur metabolism, and localizes to the nucleus and cytosol. It has been linked to fruit color and development, salt tolerance, disease resistance, brassinosteroid and abscisic acid sensitivity, root thickness, and hypocotyl morphology. Related genes in other species are linked to calcium ion homeostasis, hypocotyl elongation, rind color, spotted rind, and carotenoid biosynthesis.
