CAM — Cucumis melo

Summary

MELO3C014322.2 (symbol CmCAM) on melon chromosome 6 encodes a calmodulin-like protein containing EF-hand calcium-binding domains, with annotated molecular functions including calcium ion binding, protein domain specific binding, and enzyme modulator activity. The gene is associated with translation elongation and NO storage, and its product localizes to the cytoplasm and myosin II complex. In melon, CmCAM is associated with photosynthetic rate measured as CO2. Studies of related genes in other species connect the family to fruit length and shape, calcium concentration, chlorophyll content, quantum yield, net photosynthetic rate, transpiration rate, stomatal resistance, photochemical quenching, and drought tolerance, though these associations are not yet established for CmCAM itself.
