This paper reports sequencing of cryIA gene fragment encoding toxin domain isolated from Btk isolates of B. thuringiensis using PCR technique and cloned with pGEM-T vector. To determine the full sequence of the 2-kb gene fragment, a series of mutants unidirectionally deleted at the 5'-end were constructed. Mutation was done using Erase-a Base-System kit. Three DNA mutants with appropriate degree of deletion and the un-mutated DNA were chosen for sequencing.
