Fuente: WIPO "biotechnology" Novel delta-endotoxin genes cry26Aa1 and cry28Aa1 isolated from Bacillus thuringiensis ssp. finitimus, whose expression results in novel delta-endotoxins, are disclosed herein. The invention also discloses compositions and formulations containing the toxins that are capable of controlling insect pests. The invention is further drawn to methods of making the toxins and to methods of using the genes, for example in microorganisms to control insect pests or in transgenic plants to confer insect resistance.
