Soybean mosaic virus (SMV) is seed and aphid transmitted and can cause significant reductions in yield and seed quality in soybean (Glycine max). The roles in seed and aphid transmission of selected SMV-encoded proteins were investigated by constructing mutants in and chimeric recombinants between SMV 413 (efficiently aphid and seed transmitted) and an isolate of SMV G2 (not aphid or seed transmitted). As previously reported, the DAG amino acid sequence motif near the amino terminus of the coat protein (CP) was the major determinant in differences in aphid transmissibility of the two SMV isolates, and helper component proteinase (HC-Pro) played a secondary role. Seed transmission of SMV was influenced by P1, HC-Pro, and CP. Replacement of the P1 coding region of SMV 413 with that of SMV G2 significantly enhanced seed transmissibility of SMV 413. Substitution in SMV 413 of the two amino acids that varied in the CPs of the two isolates with those from SMV G2, G to D in the DAG motif and Q to P near the carboxyl terminus, significantly reduced seed transmission. The Q-to-P substitution in SMV 413 also abolished virus-induced seed-coat mottling in plant introduction 68671. This is the first report associating P1, CP, and the DAG motif with seed transmission of a potyvirus and suggests that HC-Pro interactions with CP are important for multiple functions in the virus infection cycle.

Differential Cultivars

A new Soybean mosaic virus (SMV) strain was isolated in Korea and designated as G7H. Its virulence on eight differentials and 42 Korean soybean cultivars was compared with existing SMV strains. G7H caused the same symptoms as G7 did on the eight differential cultivars. However, it caused different symptoms on the G7-immune Korean soybean cultivars; G7H caused necrosis in Suwon 97 (Hwangkeumkong) and Suwon 181 (Daewonkong), and a mosaic symptom in Miryang 41 (Duyoukong), while G7 caused only local lesions on those varieties. The nucleotide sequence of the cylindrical inclusion region of G7H was determined and compared with other SMV strains. G7H shared 96.3 and 91.3% nucleotide similarities with G2 and G7, respectively; whereas G7 shared 95.6% nucleotide similarity with G5H.

The leaves of soybean cv. ZheA8901 show various symptoms (necrosis, mosaic and symptomless) when infected with different strains of Soybean mosaic virus (SMV). Based on a proteomic analysis performed with tandem mass tags (TMT), 736 proteins were differentially expressed from soybean samples that showed asymptomatic, mosaic and necrosis symptoms induced by SMV strains SC3, SC7, and SC15, respectively. Among these, GmGSTU13 and APX (ascorbate peroxidase) were only upregulated in mosaic and symptomless leaves, respectively. The protein level of GmGSTU13 determined by Western blot was consistent with TMT analysis, qRT-PCR analysis showed that GmGSTU13 mRNA levels in mosaic plants was 5.26- and 3.75-fold higher than that in necrotic and symptomless plants, respectively. Additionally, the expression of viral coat protein (CP) gene was increased, and serious mosaic symptoms were observed in GmGSTU13-overexpressing plants inoculated with all three SMV strains. These results showed that GmGSTU13 is associated with the development of SMV-induced mosaic symptoms in soybean and that APX is upregulated in symptomless leaves at both the transcriptional and protein levels. In APX gene-silenced soybean plants, the relative expression of the viral CP gene was 1.50, 7.59 and 1.30 times higher than in positive control plants inoculated with the three SMV strains, suggesting that the upregulation of APX may be associated with lack of symptoms in soybean infected with SMV. This work provides a useful dataset for identifying key proteins responsible for symptom development in soybean infected with different SMV strains.

Infection of soybean plants with Soybean mosaic virus (SMV), which is transmitted by aphids and through seed, can cause significant reductions in seed production and quality. Because seedborne infections are the primary sources of inoculum for SMV infections in North America, host-plant resistance to seed transmission can limit the pool of plants that can serve as sources of inoculum. To examine the inheritance of SMV seed transmission in soybean, crosses were made between plant introductions (PIs) with high (PI88799), moderate (PI60279), and low (PI548391) rates of transmission of SMV through seed. In four F2 populations, SMV seed transmission segregated as if conditioned by two or more genes. Consequently, a recombinant inbred line population was derived from a cross between PIs 88799 and 548391 and evaluated for segregation of SMV seed transmission, seed coat mottling, and simple sequence repeat markers. Chromosomal regions on linkage groups C1 and C2 were significantly associated with both transmission of isolate SMV 413 through seed and SMV-induced seed coat mottling, and explained ≈42.8 and 46.4% of the variability in these two traits, respectively. Chromosomal regions associated with seed transmission and seed coat mottling contained homologues of Arabidopsis genes DCL3 and RDR6, which encode enzymes involved in RNA-mediated transcriptional and posttranscriptional gene silencing.
