Conover (1948) first recognized that soybean
mosaic disease was caused by more than one strain
of SMV.Since then,pathogenic variability among
SMV isolates has been widely reported in the US

and Japan (Cho & Goodman,1979; Takahashi
et al.,1980),and several SMV resistance genes
have been identified.So far,there are three independent
loci reported for SMV resistance,Rsv1
(Kiihl & Hartwig,1979),Rsv3 (Buzzell & Tu,
1989) and Rsv4 (Ma et al.,1995).In addition,
mapping of these resistance genes has been reported.
Yu et al.(1994) found that two RFLP
markers (PA186 and PK644a) and one SSR marker
(SM176) were closely linked to Rsv1,on the
molecular linkage group (MLG) F.Subsequently,
Rsv3 and Rsv4 were mapped to MLG B2 (Jeong
et al.,2002) and MLG D1b+W (Hayes et al.,
2000),respectively.These molecular markers
identified for SMV resistance genes could have the
potential to facilitate both marker-assisted selection
(MAS) and map-based cloning of resistance
genes.In China,Pu et al.(1982) and Chen et al.
(1986) isolated and identified eight SMV strains
(Sa-Sh) in the regions of Jiangsu and Heilongjiang
provinces of China on the basis of symptoms induced
on eight different soybean cultivars.Luo
et al.(1990) also reported six SMV strains (sd1–
sd6) in Shandong province of China.Recently,our
group has isolated and identified nine SMV strains
in Huang-Huai and in the middle and lower
Changjiang river valleys,two main soybean production
regions in China,on the basis of symptoms
induced on a set of 25 different soybean
cultivars.These SMV strains were named SC-1,
SC-2,SC-3,SC-4,SC-5,SC-6,SC-7,SC-8 and SC-
9,respectively (Wang,2000; Yang,2002).

Conover (1948)首先认识到大豆花叶病是由不止一个SMV株系引起的.自此之后,SMV分离株的病原的可变性在美国（Genetica (2006) 128:63–69 \1 Springer 2006 DOI 10.1007/s10709-005-5535-9 （这个应该是个什么杂志吧?你写得不清楚我也不太知道怎么翻,一般是不翻的直接写上就行了））和日本（Cho &Goodman,1979; Takahashi et al.,1980）被广泛的报道,并且几个SMV抗性基因被发现.到目前为止,有3个独立的SMV抗性位点被报道,分别是Rsv1 （Kiihl & Hartwig,1979),Rsv3 (Buzzell & Tu,1989) 和 Rsv4 (Ma et al.,1995).另外,这些抗性基因的图谱已经被报道了.Yu et al.(1994)在分子连锁群（MLG）F上发现2个RFLP标记(PA186 and PK644a) 和1个SSR标记(SM176)与Rsv1有紧密的连锁.随后,Rsv3 和 Rsv4 被分别定位于MLG B2 (Jeong et al.,2002)和MLG D1b+W (Hayes et al.,2000)上.这些被发现的SMV的抗性基因分子标记在标记辅助选择（MAS）和抗性基因的图位克隆技术上有潜力.在中国,Pu et al.(1982) 和Chen et al.(1986) 分离并鉴定了8个SMV株系在江苏地区和黑龙江省根据8个不同大豆品种上的诱导症状.Luo et al.(1990)也报道了山东省的6个SMV株系.最近,我们组根据一组25个不同的大豆品种上的诱导症状分离并鉴定了黄淮和长江中下游流域这2个中国大豆主产区的9个SMV株系.这些SMV株系分别被命名为SC-1,SC-2,SC-3,SC-4,SC-5,SC-6,SC-7,SC-8 和 SC- 9(Wang,2000; Yang,2002).
仅供参考,挺简单的翻译,其实你自己好好看一遍就知道什么意思了,根本不用拿到这来问啊!
