Genes encoding Pir toxins were cloned and sequenced from Photorhabdus luminescens (Enterobacteriaceae) strain Hm. Cultures of Escherichia coli expressing the Pir A and B proteins were highly toxic when fed to larvae of Plutella xylostella L. (Lepidoptera: Plutellidae), as had been reported previously. Histological examination of P. xylostella larvae fed with recombinant E. coli revealed gross abnormalities of the midgut epithelium, with profound swelling and shedding of the apical membranes… CONTINUE READING
