Response of Calcineurin B-like Protein Kinase Gene in Tomato to Various Abiotic Stresses

다국어 초록 (Multilingual Abstract)

This study describes the expression patterns of the CBL interacting protein kinase (SlCIPK) gene in Solanum lycopersicum after treatment with various abiotic stresses, such as salt, dehydration and mechanical wounding. The cDNA of the SlCIPK gene from the tomato leaf encodes 446 amino acids and shows significant homology with other plant CIPK proteins. SlCIPK is a single copy gene in the tomato genome. The organ-specific expression pattern of the SlCIPK gene revealed that the transcript of this gene was present in all tissues examined (roots, stems, leaves and flowers), with strong expression being observed in the roots. Additionally, the SlCIPK gene was upregulated in response to salt, dehydration and wounding. Moreover, SlCIPK was regulated by abscisic acid (ABA) and calcium. Taken together, these results indicate that SlCIPK gene may play a role in the response to abiotic stresses via ABA-mediated calcium signaling.
