This thesis studied on bacillus thuringiensis strain bt886 which was separated and selected by researchers of our laboratory. according to the observation of crystal shape and the bioassay of motschulsky and fairmaire, bacillus thuringiensis strain bt886 was identified as cry3 type, and the conclusion was assured by the further study on molecular level. the 1956 base pairs full lengrh homological cry3aa gene which was toxic to motschulsky was cloned and sequenced
以該菌株為材料，克隆出了對光肩星天牛（ anoplophralabripennis （ motsch . ） ）具有毒殺作用的cry3aa同源基因，並且對該基因進行了人工改造、人工合成、大腸桿菌表達、生物活性測定、雙元表達載體的構建以及對楊樹的轉化等一系列研究，主要結果如下： （ 1 ）顯微觀察該菌株所形成的伴孢晶體為方形。Is toxic to tenebrio molitor l. the homological cry3aa gene was modified according to the characters of poplus genes and the other features of eukaryotic gene, and was artificially synthesized. the original and modified homological c / y3aa gene were cloned into binary vector pb121 and pbin438 respectively, and transplanted into 84k clone ( p. tomentos x p. glandulossa ) to breed new anti - insects tree species
通過對氨基酸密碼子的偏好、使用頻率、多聚腺苷酸信號序列（ ppss ） 、 mrna不穩定序列（ dst ）以及kozak等結構的優化改造，人工設計、合成了預期能在楊樹中高效表達的毒蛋白基因modifiedcry3aa同源基因； （ 4 ）利用強啟動子表達載體pet30 - b完成了cry3aa同源基因在大腸桿菌中的表達。Suqian is the hometown of poplar and has a wood accumulation volume of 7, 000, 000 cubic meters
