| abstract |
The subject invention concerns Bacillus thuringiensis isolates designated B.t. PS157C1, B.t. PS86A1, and B.t. PS75J1, which are active against aphid pests. Thus, these isolates, or variants thereof, can be used to control such pests. Further, genes encoding novel delta -endotoxins can be removed from these isolates and transferred to other host microbes, or plants. Expression of the delta -endotoxins in microbe hosts results in the control of aphid pests, whereas transformed plants become resistant to aphid pests. |
