| Research Abstract |
1. Screening of a scarab-cidal B.thuringiensis (1999)
In order to find of a scarab-cidal B.thuringiensis, we were screening our B.thuringiensis stocks.
2. Analysis of the scarab-cidal B.thuringiensis strain (gallariae BBT2-8)(2000)
We found the scarab-cidal Bt.BBT2-8, then we cloned the crystal protein genes (cryB28 gene) have a scarab-cidal activity. This cryB28 gene was expressed in E.coli and acrystariferous B.thuringiensis strain (BT51). The expression products had a highly activity against scarabe.
3. Screening of a nematoda-cidal B.thuringiensis (1999-2000)
In order to find of a nematoda-cidal B.thuringiensis, we were screening our B.thuringiensis stocks by using PCR.We could not find nematodacidal B.thuringiensis strains.
4. Screening of novel lepidopteran-cidal B.thuringiensis (1999)
In order to find of novel lepidopteran-cidal B.thuringiensis, we were screening our B.thuringiensis stocks. We picked up the novel lepidopteran acitive Bt strain (wuhanensis), then we cloned the novel cry1 gene (cry1Db1) from wuhanensis have insecticidal activities against Spodoptera litura, Plutella xylostella and Bombyx mori.
