CPR5 — Cucumis melo

Summary

MELO3C007803.2 (symbol CmCPR5) on melon chromosome 9 encodes a protein with a CPR5_C domain that exhibits cyclin-dependent protein kinase inhibitor activity, mRNA binding, and protein binding. The gene is associated with flower sex determination, sex differentiation, and photoperiodic flowering in melon. It is linked to negative regulation of the cell cycle and leaf senescence, upregulation of DNA endoreduplication, trichome morphogenesis, sepal giant cell development, systemic acquired resistance, and responses to ethylene and other organisms. Associations include leaf growth and development, trichome morphology, disease tolerance, drought tolerance, root meristem development, cell elongation, and seed germination. The protein localises to the nucleus, nuclear envelope, nuclear speck, endoplasmic reticulum, and membrane. Studies of related genes in other species link the family to ethylene sensitivity, viral and powdery mildew resistance, heat stress tolerance, and cellular redox balance.
