Role of mitochondrial complex I genes in host plant expansion of Bactrocera tau (Tephritidae: Diptera) by CRISPR/Cas9 system

open access: yesInsect Science, EarlyView.
The role of 3 mitochondrial complex I gene in host expansion of Bactrocera tau was verified by CRISPR/Cas9 gene editing system. A stable homogenous strain (Btndufa7‐/‐) of B.tau was established after silencing Ndufa7. The reduced size of larvae and pupae of Ndufa7 knockout strain was first found.Then different levels of fitness and relative expression ...
