PtoJAZ gene family analysis in Poplar 741 and insect resistance identification for PtoJAZ10
This study comprehensively characterizes the 39-member PtoJAZ gene family in *Populus tomentosa* 741 and demonstrates that the overexpression of the MeJA- and herbivory-responsive PtoJAZ10 enhances insect resistance in transgenic tobacco by modulating jasmonic acid/abscisic acid levels, antioxidant enzyme activities, lignin accumulation, and key defense-related signaling pathways.
