PETE — Cucumis sativus

Summary

CsPETE, encoded by the cucumber gene CSA_3G875430 on chromosome 3, produces a plastocyanin family protein with copper-binding and electron transfer activity, localised to the chloroplast thylakoid lumen and membrane. The gene is associated with photosynthetic electron transport, copper ion homeostasis, and responses to copper and UV light. It has been linked to chlorophyll fluorescence, meristem growth and structural organisation, phyllome and root cap development, cell wall organisation, and both male and female gamete generation. Associations with agronomic traits include photosynthetic rate, quantum yield, herbicide sensitivity, disease tolerance, zinc sensitivity, and various aspects of root, leaf, inflorescence, and meristem development. Studies of related genes in other species connect the family to photosynthetic electron transport, seed yield, salt tolerance, and zinc deficiency tolerance.
