Reduced plant nutrition under elevated CO2 depresses the immunocompetence of cotton bollworm against its endoparasite
Estimating the immunocompetence of herbivore insects under elevated CO2 is an important step in understanding the effects of elevated CO2 on crop-herbivore-natural enemy interactions. Current study determined the effect of elevated CO2 on the immune response of Helicoverpa armigera against its parasitoid Microplitis mediator. H. armigera were reared in growth chambers with ambient or elevated C...
متن کاملCross-resistance and interactions between Bt toxins Cry1Ac and Cry2Ab against the cotton bollworm
To delay evolution of pest resistance to transgenic crops producing insecticidal proteins from Bacillus thuringiensis (Bt), the "pyramid" strategy uses plants that produce two or more toxins that kill the same pest. We conducted laboratory diet experiments with the cotton bollworm, Helicoverpa armigera, to evaluate cross-resistance and interactions between two toxins in pyramided Bt cotton (Cry...
متن کاملDelayed resistance to transgenic cotton in pink bollworm.
Transgenic crops producing Bacillus thuringiensis (Bt) toxins kill some key insect pests and thus can reduce reliance on insecticides. Widespread planting of such Bt crops increased concerns that their usefulness would be cut short by rapid evolution of resistance to Bt toxins by pests. Pink bollworm (Pectinophora gossypiella) is a major pest that has experienced intense selection for resistanc...
متن کاملEndophytic bacteria in the rice plant.
Endophytic bacteria are defined as bacteria detected inside surface-sterilized plants or extracted from inside plants and having no visibly harmful effects on the plants. Various kinds of endophytic bacteria, such as Pantoea, Methylobacterium, Azospirillum, Herbaspirillum, Burkholderia and Rhizobium etc., have been found inside rice plants. This minireview summarizes and discusses recent studie...
متن کاملScreening methods and enzyme profile of agricultural plant-endophytic bacteria
Nowadays plant endophytic bacteria have found diverse and useful applications in biotechnology; therefore, much attention has been paid to the isolation, identification, and evaluation of these microorganisms. Since the sterilizing plant tissue surfaces from epiphytic bacteria is difficulty, the efficacy of three different screening methods for endophytic bacteria including 1- HClO sterilizatio...
