Two isolates of Capsicum chlorosis virus (CaCV, genus Tospovirus) from tomato (CaCV-To-Ind) and chilli (CaCV-Ch-Pan), collected from Haryana and Uttar Pradesh states of northern India respectively, were compared. A comparison of the amino acid sequences of their N genes revealed more than 96% identity, confirming that the virus isolates in India have a high degree of sequence conservation and are closely related to Australian isolates. Analysis of the host range of CaCV revealed no biological difference between the isolates, but they differed from CaCV-Australia. The nucleotide sequences of S, M and L RNA of CaCV-Ch-Pan were determined. The S RNA contains 3,105 nucleotides (nt), with NSs and N genes of 1,320 and 828 nt, respectively. The M RNA consists of 4,821 nt, with an NSm gene of 927 nt and a Gn/Gc gene of 3,366 nt. The intergenic regions of S and M RNA contain 824 and 425 nt, respectively. The L RNA consists of 8,912 nt, with an RNA-dependent RNA polymerase gene of 8,634 nt.
从印度北部哈里亚纳邦和北方邦采集的番茄(CaCV-To-Ind)和辣椒(CaCV-Ch-Pan)中的两种辣椒褪绿病毒(CaCV,Tospovirus 属)分离株进行了比较。对其 N 基因的氨基酸序列进行比较,发现它们的同源性超过 96%,证实了印度的病毒分离株具有高度的序列保守性,与澳大利亚的分离株密切相关。对 CaCV 的宿主范围进行分析表明,分离株之间没有生物学差异,但与 CaCV-Australia 不同。确定了 CaCV-Ch-Pan 的 S、M 和 L RNA 的核苷酸序列。S RNA 包含 3105 个核苷酸(nt),NSs 和 N 基因分别为 1320 和 828 nt。M RNA 由 4821 nt 组成,其中 NSm 基因 927 nt,Gn/Gc 基因 3366 nt。S 和 M RNA 的内含子区分别为 824 和 425 nt。L RNA 由 8912 nt 组成,其中 RNA 依赖性 RNA 聚合酶基因 8634 nt。
