CP1 — Solanum tuberosum

Summary

StCP1 (PGSC0003DMG400001204) on potato chromosome 1 encodes a centrin/CML-like protein with EF-hand domains and calcium ion binding activity, and is annotated as an enzyme modulator. The gene is associated with a wide range of biological processes including the GABA shunt, hormone metabolism, sucrose anabolism, fermentation, and responses to water and host organisms. It is linked to plastid and cytosol localisation. Agronomically, StCP1 has been connected to drought tolerance, photosynthetic rate, stomatal resistance and opening, relative chlorophyll content, nitrogen and proline content, shoot fresh weight, root length, and rhizome formation. Studies of related genes in other species link the family to salt stress tolerance, and sequence similarity connections further associate the family with traits such as seedling vigor, leaf water potential, fruit firmness, and water use efficiency.
