Expression of the Cry10Aa toxin in transgenic tomato confers tolerance to the tomato leafminer (Tuta absoluta)

•This work reports for the first time the expression of the cry10aa toxin in tomato plants.•This study presents the successful development of a GM tomato resistant to leafminer (Tuta absoluta).•ELISA revealed a higher accumulation of cry10aa protein.•The bioassay performed with T. absoluta showed a statistically significant difference between the emergence of adults for one line when compared to the wild type.•Data suggests a reduction of up to 50% in the emergence of adults for the line L10, which presented the highest toxin level in leaves.
