| Sumario: | Laccase (LAC) plays important roles in different plant development and defense processes. In this study, we identified laccase genes (<i>CsLAC</i>s) in <i>Camellia sinensis</i> cv ‘Longjing43′ cultivars, which were classified into six subclades. The expression patterns of <i>CsLAC</i>s displayed significant spatiotemporal variations across different tissues and developmental stages. Most members in subclades II, IV and subclade I exhibited contrasting expression patterns during leaf development, consistent with a trade-off model for preferential expression in the early and late developmental stages. The extensive transcriptional changes of <i>CsLAC</i>s under different phytohormone and herbivore treatment were observed and compared, with the expression of most genes in subclades I, II and III being downregulated but genes in subclades IV, V and VI being upregulated, suggesting a growth and defense trade-off model between these subclades. Taken together, our research reveal that <i>CsLAC</i>s mediate multi-perspective trade-offs during tea plant development and defense processes and are involved in herbivore resistance in tea plants. More in-depth research of <i>CsLAC</i>s upstream regulation and downstream targets mediating herbivore defense should be conducted in the future. |
