摘 要: | 为了更科学、合理地检测、检疫马铃薯Y病毒(PVY)株系,和全面掌握侵染中国大田马铃薯的PVY株系情况,总结了PVY株系的分类方法,分析了中国大田马铃薯感染的PVY株系谱。认为目前广泛使用的血清型划分法、基因组重组与否划分法、PTNRD效应划分法、过敏反应互作基因划分法,以及Singh等提出的株系群划分法都无法对PVY株系予以完全合理的划分。提出有必要鉴定PVY基因组中决定马铃薯病理效应的基序并通过对基序测序来鉴定PVY株系,通过对株系间基因组差异区段的短序列测序来鉴定PVY株系是目前最接近基序测序分类法的思路。指出感染中国大田马铃薯的PVY目前有PVYO、PVYN、PVYNTN、PVYN:O、PVYN-Wi和PVYNW这6种株系,隶属于2个株系群PVYO和PVYN,其中PVYN株系和PVYN株系群病样占绝大多数,以非重组株系为主,但重组株系已占一定比例,其发展趋势值得关注。

Progress of Potato virus Y Strain Classification and Analysis of Profile of Potato virus Y Strains Infecting Potato in China |

Abstract: | In order to better understand the progress of Potato virus Y (PVY) strain classification and know the profile of PVY strains infecting potato in China, the current PVY strain classification methods are reviewed, and all the reported PVY isolates from infected potato samples in China are counted. So far PVY strains can be classified by the following five methods: classification by serotypes, classification based on genome recombination, classification based on potato tuber necrotic ringspot disease (PTNRD), classification based on hypersensitive resistance genes, classification by strain groups. But all these methods can not fully and well classify the reported PVY strains. Therefore, more studies are still in need on PVY strain classification. According to our statistical results of all the reported PVY isolates from infected potato samples in China, six PVY strains (PVYO, PVYN, PVYNTN, PVYN:O, PVYN-Wi and PVYNW) have successfully infected the potato plants grown in the fields in China. PVYN is the predominant one of them. These six PVY strains can be sorted into two strain groups (PVYO and PVYN) and PVYN group is the predominant one. Among the reported PVY isolates most are non-recombinant strains. But as recombinant strains have also accounted for a certain proportion their development trend should be worthy of attention. |
