摘    要: 花生病毒病是影响花生生产的重要病害。近10年来,花生矮化病毒(PSV)、花生条纹病毒(PStV)和番茄斑萎病毒属(Tospovirus)病毒分子生物学研究进展,极大地丰富了对上述病毒基因组结构、遗传变异、进化的认识,以及病毒种、亚组和株系的科学划分。对PSV来说,提出了2个亚组的划分,而我国PSV株系血清学和RNA3全序列的分析,明确它们独自构成第3个新的亚组。对我国和东南亚国家PStV株系CP基因序列同源性的分析,说明在这些国家和地区PStV是单独进化的,形成不同症状类型的株系。Tospovirus属病毒分子生物学研究的深入使得该属病毒从番茄斑萎病毒(TSWV)1种增加到13种,其中侵染花生的病毒达5种,分布于不同的国家和地区。

关 键 词:花生病毒  花生矮化病毒  花生条纹病毒  番茄斑萎病毒属病毒  分子生物学

Abstract:Peanut virus diseases are economically important to peanut production. In recent 10 years, great progress has been made in researches on molecular biology of Peanut stunt virus (PSV), Peanut stripe virus (PStV) and Tospoviruses infecting peanut, which made better understanding of the genome, genetic diversity, evolution and determination of species, subgroup and strain of the viruses. Following molecular characterization of two subgroups of PSV, a third subgroup was established from PSV Chinese strains based on serology and sequence analysis of RNA3. It was demonstrated that PStV strains with symptom diversity were evolved independently in China and some Southeast Asian countries based on comparison of sequence homology of coat protein gene. The progress in molecular biology of Tospovirus has increased the viruses from Tomato spotted wilt virus (TSWV) alone to 13 species in past 10 years, among which 5 species infect peanut.
Keywords:viruses infecting peanut  Peanut stunt virus  Peanut stripe virus  Tospoviruses  molecular biology
