Lignin is a plant component that is of great importance in many industrial and agricultural disciplines. However, how WRKYs regulate plant lignin synthesis pathways and defense against insects is largely unknown. Here, we investigate WRKYs in Nicotiana benthamiana, a model plant and biofactory widely used worldwide, elucidating their responses to the Bemisia tabaci whitefly, a globally significant agricultural pest, and their functions in regulating plant defense by regulating lignin synthesis. Firstly, we identified a total of 118 NbWRKYs in the N. benthamiana genome and performed necessary bioinformatics analyses. Then, we studied nine whitefly-inducible NbWRKYs and found that they were localized in the nucleus, significantly expressed in leaf tissues, and affected the phytohormone pathways. Meanwhile, NbWRKY21, NbWRKY45, NbWRKY81, and NbWRKY117 were proved to be involved in defense against whiteflies. Additionally, through DNA-TFs interaction experiments, we demonstrated that the WRKYs activated the expression of key genes—Cinnamate-4-hydroxymate (C4H), 4-coumarate-CoA ligase (4CL), and Cinnamoyl-CoA reductase (CCR)—in the lignin synthesis pathway. Specifically, NbWRKY81 activated the NbC4H and Nb4CL, while NbWRKY45 promoted NbCCR, by binding to their promoters, affecting whitefly feeding behavior, and therefore enhancing whitefly defense.

Methyleugenol content in the essential oil from Melaleuca bracteata leaves is 90.46 %, making it an excellent material for assessing methyleugenol’s biosynthetic pathway. Eugenol synthase (EGS) and eugenol-o-methyltransferase (EOMT) represent key genes in methyleugenol’s biosynthetic pathway but their respective functions are unclear. In this study, overexpression and virus-induced gene silencing (VIGS) techniques were applied to investigate the major regulatory gene among MbEGS1, MbEGS2, MbEGS3, and MbEGS4 in the biosynthesis pathway of methyleugenol. We also aimed to examine the coordination mechanism between EGS and EOMT in methyleugenol production by M. bracteata. The data revealed MbEGS4 transcription and methyleugenol content were most significantly increased after overexpression of the MbEGS1–4 gene in M. bracteata and Fragaria vesca. Conversely, MbEGS4 transcription and methyleugenol content were most significantly reduced after MbEGS1–4 gene silencing by VIGS in M. bracteata. These results underscore a major regulatory role for the MbEGS4 gene in the biosynthetic pathway of methyleugenol in M. bracteata. Remarkably, upon overexpression and silencing of MbEOMTs, the transcription levels of MbEGSs were notably upregulated, with MbEGS4 showing the highest increase.
