<p>B. thuringiensis genes encoding toxins active against nematode pests have been cloned from the strains PS80JJ1, PS158D5, PS167P, PS169E, PS177F1, PS177G, PS204G4 and PS204G6. The toxins are active especially against Panagrellus redivivus as examplified in the application. The DNAs encoding the toxins can be used to transform various hosts, such as plants, to express the toxins.</p> |
