摘要
:对引起我国南瓜曲叶病的病毒分离物DNA的克隆和序列分析表明 ,中国南瓜曲叶病毒DNAA由 2 741个核苷酸组成 ,共编码 6个开放阅读框 (ORF) ,其中病毒链有 2个ORF :AV1 (2 56aa)和AV2 (1 40aa) ,AV1为外壳蛋白基因 ;病毒链的互补链有 4个ORF ,AC1 (2 4 3aa)编码复制酶基因 ,AC2 (1 34aa)编码反式激活蛋白 ,AC3(1 36aa)和AC4(1 72aa) ,该病毒属于旧世界Begomoviruses,是一个粉虱传播的联体病毒。
Sequence analysis of virus isolation DNA of Squash leaf curl disease shows that Squash Leaf Curl Virus (SLCV\|CHI) contains 2741nt, which encode six Open Reading Frames (ORFs). Two of them are on virus sense strand:AV1 (256aa) and AV2 (140aa). AV1 encode coat protein. The other of ORFs are on complementary sense strand:AC1 (replicase gene, 243aa), AC2 (transactivtor,134aa), AC3 (136aa) and AC4 (172aa). The virus belongs to one number of begomoviruses from old world.
