CP1 — Solanum lycopersicum

Summary

SlCP1 (SOLYC01G058720.4) on tomato chromosome 1 encodes a protein containing EF-hand domains, with calcium ion binding confirmed as its molecular function. The gene is associated with a wide range of biological processes including regulation of localization, phototransduction, nitrogen fixation, zeaxanthin anabolism, and the GABA shunt. It has been linked to numerous agronomically important traits such as fruit weight, fruit firmness, fruit shape and size, plant height, stem diameter, leaf number, chlorophyll content, net photosynthetic rate, quantum yield, water use efficiency, sugar and amino acid content, proline content, germination ratio, seedling vigor, and drought tolerance. The protein localizes to plastids and the cytosol. Studies of related genes in other species link the family to salt stress tolerance.
