| 摘 要： | 根据Gen Bank中Cry1A类基因序列设计一对特异性引物，以苏云金芽孢杆茵猝倒亚种质粒DNA为模板，应用PCR扩增技术得到一大小约为3．6kb的DNA片段(Cry1Aa13)．通过引物步行法测定该片段长3598bp，其中开放阅读框(ORF)长3540bp，编码1180个氨基酸，分子量为133．49kD，等电点pI=5．0．序列比较表明该基因与Cry1Aa类基因高度同源(达95％以上)，该基因已在GenBank中登录，登录号为AF510713，并被Btδ-内毒素基因国际命名委员会正式命名为Cry1Aa13。

| Abstract: | Cry1Aa13 gene had been cloned by PCR procedure from Bacillus thuringiensis subsp sotto plasmids with the primers designed according to the Cry1A sequence in the GenBank. Sequencing was done to the fragments using primer walking method and its length is 3598bp. Cry1Aa13 contained an 3540bp ORF that predicted a protein of 1180 amino acid with Mr=133.49kD and pI=5.0. The amino acid sequence of Cry1Aa13 gene shows more than 95% identity to other Cry1Aa, and the sequence was registered in GenBank(Accession Number is AF510713) which was designated Cry1Aa13 gene as a novel gene by Bt delta-endotoxin nomenclature committee. |
