Abstract
Recombinant DNA coding for an insecticidally active form of the Bacillus thuringiensis endotoxin which DNA is derived from the chromosome plasmids of the A20 strain of Bacillus thuringiensis. The recombinant genes may be of the 6.6, 5.3 or 4.5 types. Further discloses a truncated chimetic endotoxin-producing gene derived from the 5.3 and 4.5-type genes of strain A20.
