| 6. | When the adults entered a new potontial distribution pattern , they formed aggregating groups with different sizes , and dispersed all around 在光肩星天牛虫道内,花绒坚甲位于食物链最后环节,其数量占食物链中昆虫总数的15 . 9 % 。 |
| 7. | 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 以该菌株为材料,克隆出了对光肩星天牛( anoplophralabripennis ( motsch . ) )具有毒杀作用的cry3aa同源基因,并且对该基因进行了人工改造、人工合成、大肠杆菌表达、生物活性测定、双元表达载体的构建以及对杨树的转化等一系列研究,主要结果如下: ( 1 )显微观察该菌株所形成的伴孢晶体为方形。 |
| 8. | Further sequence analysis show that only 6 base pairs of nucleotide and 2 amino acids are different between them . the homological cry3aa gene was expressed in escherichia coli . . and the expressed products which contain a fused peptide of 66 - 97 kilo - dalton was observed by means of sds - page 生物活性测定结果表明该菌株对榆蓝叶甲( pyrrhaltaaenescens ( fairmaire ) )和光肩星天牛等鞘翅目昆虫具有较高的毒力,因此初步确认该菌株属于cry3类; ( 2 )发现该菌株中编码毒蛋白的基因位于质粒上,并且已经成功地克隆到该基因。 |
