SAPK7 — Cucumis sativus

Summary

CSA_4G515040, designated SAPK7, encodes a non-specific serine/threonine protein kinase with protein serine/threonine kinase activity (EC 2.7.11.1) and ATP binding, belonging to the Ser/Thr kinase family. In cucumber, this gene is associated with ABA signaling, osmotic response, stomatal closure and movement, seed germination, seedling development, fruit development, cell cycle, protein phosphorylation, signal transduction, and defence response to bacteria. It localises to the cytosol, cytoplasm, and nucleus. SAPK7 has been linked to drought tolerance, transpiration rate, water use efficiency, stomatal resistance, stomatal opening, and sugar content. Related genes in other species, such as rice SAPK1, SAPK2, SAPK9, and SAPK10, connect the family to stress signaling pathways.
