Genome-wide identification, classification and expression analysis of laccase family members in Solanum lycopersicum.

ABSTRACT: Laccase, a copper-containing polyphenol oxidase, is integral to plant growth and development, primarily due to its involvement in lignin and flavonoid biosynthesis, as well as its role in mediating plant responses to diverse biotic and abiotic stresses. Despite its importance, a comprehensive and systematic analysis of the laccase gene family in tomato has not been conducted until now. This study identifies eighteen laccase genes, unevenly distributed across seven chromosomes, within the tomato genome. Phylogenetic analysis categorizes these eighteen SlLACs into five distinct groups, corresponding to the established groups in Arabidopsis. Motif analysis indicates the presence of ten conserved motifs within the SlLACs. Gene duplication analysis reveals collinearity between the eighteen SlLA
