AI Technical Summary
The development of resistance to single Cry1F proteins in maize plants by Spodoptera frugiperda populations poses a significant challenge, and existing Cry1Da proteins exhibit a narrow spectrum of activity and variable toxicity against lepidopteran pests, limiting their effectiveness.
A transgenic maize event, ME240913, is developed with a truncated Cry1Da protein optimized for expression in maize, providing high toxicity against various Spodoptera frugiperda populations, including those resistant to Cry1F, and includes unique nucleic acid sequences for detection and potential gene pyramiding.
The ME240913 event effectively controls leaf damage caused by Spodoptera frugiperda populations, including resistant ones, with high mortality rates and offers a distinct mechanism of action for enhanced pest control, suitable for pyramiding with other insecticidal genes.
