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 ...

Jasmonates enhance plants tolerance grown in Cd‐contaminated environments: A comprehensive overview

open access: yesAnnals of Applied Biology, EarlyView.
Jasmonates (JAs) enhance plant tolerance to cadmium (Cd) stress by activating antioxidant defences but may reduce Cd uptake, limiting their effectiveness for phytoremediation. This review compiles studies that evaluated the effects of JA application on plants grown in Cd‐contaminated environments. Abstract Cadmium (Cd) is a toxic heavy metal and one of
