甘蔗黄叶病毒基因型研究进展

Research Progress of Sugarcane Yellow Leaf Virus Genotypes

综述了世界甘蔗黄叶病毒(Sugarcane yellow leaf virus,ScYLV)基因型的研究进展,研究表明,ScYLV为正单链RNA病毒,全基因组由5895～5899个核苷酸组成。目前基于ScYLV基因组核苷酸序列的对比可将ScYLV划分为7种基因型,其中BRA基因型为主要基因型。不同基因型的ScYLV存在致病性差异。

This paper summarized a brief review about the recent research progress of ScYLV. The genome of sugarcane yellow leaf virus （ScYLV） is consists of a positive-sense single stranded RNA of 5895-5899 nucleotides. At present, the SeYLV based on genomic nucleotide sequence alignment can be divided into seven genotypes, and BRA genotype is as the main genotype. There are pathogenic differences between the different SeYLV genotypes.
