Abstract:Cry toxins produced by Bacillus thuringiensis (Bt) are toxic to Lepidoptera,
Coleoptera, and Diptera, but display very low activity against aphids.
Recently, Cry41-related toxin was found to show moderate toxicity
against Myzus persicae with the 50%
lethal concentration (LC50) of 32.7 μg/mL, and its
mode of action was proposed
to be the acceleration of the apoptosis of aphid cells by enhancing
Cathepsin B activity. This study focused on constructing Cry41-related
mutants against M. persicae based on
its intera… Show more
