“…The yield losses due to mosaic disease caused by SbMV range from 8% to 50% under natural field conditions and can reach up to 100% in severe outbreaks (Arif, Stephen, & Hassan, 2002;Cui, Chen, & Wang, 2011;Hill, 2003) and when coinfected with Bean pod mottle virus (BPMV), Cowpea mosaic virus (CPMV), AMV, and TRSV (Cui et al, 2011;Hwang et al, 2011;MalapiNelson, Wen, Ownley, & Hajimorad, 2009). Symptoms induced by SbMV depend on the host genotype, the virus strain, the plant age, and the temperatures at which the plants are grown (Hill, 2003).…”

“…Nine distinct strain groups, G1-G7, G7A, and C14 have been reported based on differential reactions on selected soybean cultivars (Cho & Goodman, 1979;Lim, 1985). SbMV detection is based on ELISA, RT-PCR, real time-PCR, near infrared spectroscopy, and aquaphotomics (Cui et al, 2011;Jinendra et al, 2010). Plants grown from SbMV-infected seed often constitute the primary inoculum source with secondary spread, which occur rapidly, by aphids (Cui et al, 2011).…”

“…SbMV strain G7 overcomes the resistance conferred by Rsv1 and results in systemic necrosis of virus-infected plants. The resistance conferring genes have been deployed in China, the United States, Canada, and other countries for developing SbMV-resistant soybean cultivars (Cui et al, 2011).…”

“…A number of soybean accessions (germplasm) and cultivars carrying resistance to SbMV have been identified and used in the breeding programs (Cui et al, 2011). Since SbMV is genetically variable and continuously evolving via recombination and spontaneous mutations, strong directional breeding line selection can lead to the occurrence of resistance-breaking isolates (Gagarinova, Babu, Stromvik, & Wang, 2008).…”

GmSN1 enhances virus resistance in plants most likely by affecting the expression of signal transduction and immune response genes. Soybean mosaic virus (SMV) infection causes severe symptom and leads to massive yield loss in soybean (Glycine max). By comparative analyzing gene expression in the SMV-resistant soybean cultivar Rsmv1 and the susceptible cultivar Ssmv1 at a transcriptome level, we found that a subgroup of Gibberellic Acid Stimulated Transcript (GAST) genes were down-regulated in SMV inoculated Ssmv1 plants, but not Rsmv1 plants. Sequence alignment and phylogenetic analysis indicated that one of the GAST genes, GmSN1, was closely related to Snakin-1, a well-characterized potato microbial disease resistance gene. When over-expressed in Arabidopsis and soybean, respectively, under the control of the 35S promoter, GmSN1 enhanced turnip mosaic virus resistance in the transgenic Arabidopsis plants, and SMV resistance in the transgenic soybean plants, respectively. Transcriptome analysis results showed that the up-regulated genes in the 35S:GmSN1 transgenic Arabidopsis plants were largely enriched in functional terms including "signal transduction" and "immune response". Real-time PCR assay indicated that the expression of GmAKT2, a potassium channel gene known to enhance SMV resistance when over-expressed in soybean, was elevated in the 35S:GmSN1 transgenic soybean plants. Taken together, our results suggest that GmSN1 enhances virus resistance in plants most likely by affecting the expression of signal transduction and immune response genes.

Pathogens and their vectors have coevolutionary histories that are intricately intertwined with their ecologies, environments, and genetic interactions. The soybean aphid, Aphis glycines, is native to East Asia but has quickly become one of the most important aphid pests in soybean-growing regions of North America. In this study, we used bioassays to examine the effects of feeding on soybean infected with a virus it vectors (Soybean mosaic virus [SMV]) and a virus it does not vector (Bean pod mottle virus [BPMV]) have on A. glycines survival and fecundity. The genetic underpinnings of the observed changes in fitness phenotype were explored using RNA-Seq. Aphids fed on SMV-infected soybean had transcriptome and fitness profiles that were similar to that of aphids fed on healthy control plants. Strikingly, a significant reduction in fecundity was seen in aphids fed on BPMV-infected soybean, concurrent with a large and persistent downregulation of A. glycines transcripts involved in regular cellular activities. Although molecular signatures suggested a small regulatory RNA pathway defense response was repressed in aphids feeding on infected plants, BPMV did not appear to be replicating in the vector. These results suggest that incompatibilities with BPMV or the effects of BPMV infection on soybean caused A. glycines to allot available energy resources to survival rather than reproduction and other core cellular processes. Ultimately, the detrimental impacts to A. glycines may reflect the short tritrophic evolutionary histories between the insect, plant, and virus.
