PRR2 — Cucumis melo

Summary

MELO3C013874.2, also known as CmPRR2 or CmAPRR2, encodes a GLK1/2-like protein with phosphorelay response regulator activity and sequence-specific DNA binding. Located in the nucleus, cytoplasm and cytosol, it is associated with chlorophyll metabolism, circadian rhythm, cytokinin signaling, and responses to cold, abscisic acid, salinity and bacteria. In melon, CmPRR2 is linked to rind color and spotted rind phenotypes. The gene has also been connected to fruit color, fruit development, disease resistance, salicylic acid biosynthesis, camalexin production, salt tolerance, brassinosteroid sensitivity, root thickness and hypocotyl morphology. Studies of related genes in other species link the family to calcium ion homeostasis, hypocotyl elongation, plant immunity, and carotenoid biosynthesis.
