摘要
目前已报道的造成玉米粗缩病的病原有3种，分别是玉米粗缩病毒 （ Maize rough dwarf virus, MRDV），水稻黑条矮缩病毒（ Rice black-streaked dwarf virus, RBSDV ） 和南方水稻黑条矮缩病毒（Southern rice black-streaked dwarf virus, SRBS- DV）。我国于1954年在新疆和甘肃发现该病，
Rice black-streaked dwarf virus （RBSDV） is the main pathogen that causes maize rough dwarf, rice black-streaked dwarf and wheat green dwarf in China, leading to severe damage of crop yield and quality. In this study RBSDV infected maize leaves were collected from eight areas in Henan province. RT-PCR was conducted to amplify the full-length s10 gene for sequencing. The results showed that the s10 of all the eight isolates were 1 801 bp in length which encoded a protein of 558 amino acids （aa）. The nucleotide and amino acid homology among the eight isolates were 93.0%-99.88% and 98.20% ~ 99.80%, respectively, indicating that the variation of nucleotides was more obvious than that of amino acids.
