摘要
用AcMNPVegt基因中的保守区部分片段为探针,通过Southern杂交确定SlMN-PVegt基因的位置在PstⅠ4970bp和XbaⅠ2600bp的片段上.采用双链DNA序列分析方法测序,在2600bp片段上的EcoRⅠ位点两侧得到594bpDNA碱基序列,用计算机DNASIS和PROSIS软件,将594bpDNA碱基序列所推测的氨基酸序列与AcMNPV和SliMNPV的egt基因氨基酸序列进行同源比较,其同源性分别为45%和86.5%.
The ecdysteroid UDP glucosyltransferase (EGT) gene of Spodoptera litura multinucleocapsid nuclear polyhedrosis virus ( Sl MNPV),which located within a Pst Ⅰ 4 970 bp region, was cloned using Autographa californica multinucleocapsid nuclear polyhedrosis virus ( Ac MNPV) egt gene as a probe and southern hybridization method. Partially, 594 nucleotides(nt) of Xba Ⅰ2 600 bp fragment within Pst Ⅰ 4 970 bp region was sequenced. The predicted peptide of the 594 nt exhibited a 45% and 86 5% amino acid identity with the egt polypeptides from Ac MNPV and Spodoptera littoralis multinucleocapsid nuclear polyhedrosis virus ( Sli MNPV) , respectively.
