Insecticidal toxin in root exudates from Bt corn

Article metrics

Abstract

Bt corn is corn (Zea mays) that has been genetically modified to express insecticidal toxins derived from the bacterium Bacillus thuringiensis to kill lepidopteran pests feeding on these plants. Here we show that Bt toxin is released into the rhizosphere soil in root exudates from Bt corn.
