The interactions of SMV with soybean genotypes containing different dominant R genes and an understanding of the functional role(s) of SMV-encoded proteins in virulence, transmission and pathogenicity have been investigated intensively. The SMV-soybean pathosystem has become an excellent model for the examination of the genetics and genomics of a uniquely complex gene-for-gene resistance model in a crop of worldwide importance.

“…Therefore, the chance for the occurrence of a superior SMV isolate that can overcome all resistance genes is extremely low, and pyramiding R genes may be a sound option. Indeed, the pyramiding of three R-genes using marker-assisted selection (MAS) has been reported, and potential lines may be released to support breeding programs [61,64,89,113].…”

This review summarizes the history and current state of the known genetic basis for soybean resistance to Soybean mosaic virus (SMV), and examines how the integration of molecular markers has been utilized in breeding for crop improvement. SVM causes yield loss and seed quality reduction in soybean based on the SMV strain and the host genotype. Understanding the molecular underpinnings of SMV–soybean interactions and the genes conferring resistance to SMV has been a focus of intense research interest for decades. Soybean reactions are classified into three main responses: resistant, necrotic, or susceptible. Significant progress has been achieved that has greatly increased the understanding of soybean germplasm diversity, differential reactions to SMV strains, genotype–strain interactions, genes/alleles conferring specific reactions, and interactions among resistance genes and alleles. Many studies that aimed to uncover the physical position of resistance genes have been published in recent decades, collectively proposing different candidate genes. The studies on SMV resistance loci revealed that the resistance genes are mainly distributed on three chromosomes. Resistance has been pyramided in various combinations for durable resistance to SMV strains. The causative genes are still elusive despite early successes in identifying resistance alleles in soybean; however, a gene at the Rsv4 locus has been well validated.

“…The Rsv1 locus includes at least ten alleles (Chen et al, 1991, 2001, 2002; Kiihl and Hartwig, 1979; Roane et al, 1983; Shakiba et al, 2013) and generally confers resistance to less virulent strains (G1–G4) and susceptibility or necrosis to more virulent strains (G5–G7) (Table 1) (Chen et al, 1991; Gunduz et al, 2002; Ma et al, 2002; Li et al, 2010). The Rsv3 locus contains at least six alleles (Buzzell and Tu, 1989; Gunduz et al, 2001; Cervantes‐Martinez et al, 2015; Shakiba et al, 2012) and confers resistance to more virulent strains (G5–G7) and susceptibility to less virulent strains (G1–G4) (Table 1). The Rsv4 locus has at least three alleles conferring resistance to all or most strains (G1–G7) (Buss et al, 1997; Ma et al, 2002; Gunduz et al, 2004; Shakiba et al, 2013); however, often shows resistance at early vegetative stage and delayed mild susceptibility at a later stage (Table 1) (Buss et al, 1997; Gunduz et al, 2004)…”

Soybean mosaic virus (SMV) is the most prevalent viral pathogen and economic threat to soybean production worldwide. Three independent genes harboring SMV resistance have been identified: Rsv1, Rsv3, and Rsv4. Although the resistance genes (R‐genes) have been found in some germplasm, usually they provide protection to some, but not all, viral strains. The objective of this research was to identify a new source of SMV resistance in Korean soybean accession PI 438307. The soybean genotype PI 438307 was crossed with susceptible parent ‘Essex’ (rsv), and differential parents PI 96983 (Rsv1), L29 (Rsv3), and V94‐5152 (Rsv4). F2 plants and F2:3 lines derived from all four cross combinations were screened with SMV‐G7 strain. Additionally, F2 plants obtainSed from PI 438307 (R) × Essex (S) were genotyped with two simple sequence repeat (SSR) markers on chromosome 2 (MLG D1b). Inheritance and allelic studies revealed that resistance to SMV in PI 438307 is controlled by a single dominant gene allelic to the Rsv4 locus. PI 438307 exhibited unique symptomology when compared to reported Rsv4 alleles in V94‐5152, PI 88788 and Beeson. PI 438307 was resistant to SMV‐G1 through G6 and resistant at seedling stages to SMV‐G7. Therefore, it was proposed that the new allele Rsv4‐v might be assigned to the SMV resistance in this soybean accession. Soybean sources carrying Rsv4 alleles are rare among the soybean germplasm and confer resistance to all or most SMV strains; therefore, this allele may be a good choice for breeding programs in the future.
