Potato expressing <scp> <i>Cry1C</i> </scp> and <scp> <i>Cry2A</i> </scp> confers resistance to <scp> <i>Phthorimaea operculella</i> </scp> (Lepidoptera: Gelechiidae)
This study is the first to demonstrate that Cry2A expression in potato confers resistance to PTM. It provides novel genetic resources for insect-resistant potato breeding and proposes a gene pyramiding strategy to delay the onset of resistance evolution in pest populations. Future research should focus on evaluating field resistance durability and investigating potential synergistic effects between Cry1C/Cry2A and other Bt proteins to develop multi-target pest management systems. © 2025 Society of Chemical Industry.
