Development of diamondback moth resistant transgenic cabbage and cauliflower by stacking Cry1B and Cry1C Bt genes

Abstract

Cabbage and cauliflower are extensively cultivated Cole vegetables all around the world. These are highly prone to the most notorious insect pest Plutella xylostella (diamondback moth), causing huge yield losses to the growers. Conventional breeding for host plant resistance against this pest is limited due to lack of resistance source in the available germplasm. The chemical control measures are cumbersome, costly, health hazardous and environment unfriendly. Therefore, using quaternary gene pool for incorporation of resistance genes from unrelated sources such as bacterial derived insecticidal Bt toxins through genetic engineering is a viable option. Genetic manipulation of plants through ..
