Genome-Wide Analysis of Tomato SlCCD Genes and the Role of SlCCD11 in Enhancing Salt Tolerance.

ABSTRACT: Tomato (Solanum lycopersicum L.) is an important horticultural crop. Carotenoid cyclase dioxygenase (CCD) is an enzyme responsible for cleaving carotenoids, which is involved in regulating plant growth and response to abiotic stresses. However, the role of SlCCDs in tomato stress resistance remains unclear. This study used the tomato variety 'Micro-Tom' as the material to investigate the function of SlCCDs in stress responses. Through whole-genome analysis, a total of 12 SlCCDs members (SlCCD1-SlCCD12) were identified. Systematic evolutionary analysis classified them into four branches, and members within the same branch maintained a conserved structure. The promoter analysis revealed that SlCCDs contain multiple hormones and stress response
