“…Seed can become stained by grass, leaves or dirt during harvest, or become discolored due to pathogens or pests (Figure 4). Bean pod mottle virus (BPMV) and Soybean mosaic virus (SMV) are viral pathogens that cause dark blotches on seed coats [54]. BPMV is transmitted by Cerotoma trifurcate, the bean leaf beetle; SMV is transmitted by the soybean aphid as well as other aphids [55].…”

Organically Grown Soybean Production in the USA: Constraints and Management of Pathogens and Insect Pests

Soybean is the most produced and consumed oil seed crop worldwide. In 2013, 226 million metric tons were produced in over 70 countries. Organically produced soybean represents less than 0.1% of total world production. In the USA, the certified organic soybean crop was grown on 53 thousand ha or 0.17% of the total soybean acreage in the USA (32 million ha) in 2011. A gradual increase in production of organically grown soybean has occurred since the inception of organic labeling due to increased human consumption of soy products and increased demand for organic soybean meal to produce organic animal products. Production constraints caused by pathogens and insect pests are often similar in organic and non-organic soybean production, but management between the two systems often differs. In general, the non-organic, grain-type soybean crop are genetically modified higher-yielding cultivars, often with disease and pest resistance, and are grown with the use of synthetic pesticides. The higher value of organically produced soybean makes production of the crop an attractive option to some farmers. This article reviews production and uses of organically grown soybean in the USA, potential constraints to production caused by pathogens and insect pests, and management practices used to reduce the impact of these constraints.

“…In many crops, co-infection of potyviruses with taxonomically diverse plant viruses results in disease synergism and elevation in the level of the nonpotyviruses involved (2,15,24,27). The elevation in the level of the nonpotyviruses has been attributed to suppression of gene silencing activity of helpercomponent proteinase (HC-Pro) of potyviruses (17,23).…”

“…In soybean, synergistic interaction of Bean pod mottle virus (BPMV) and Cowpea mosaic virus (CPMV), both belonging to the genus Comovirus, family Comoviridae, with SMV has been reported (2,3,15,24). Recently, however, this was attributed to the ability of HC-Pro cistron of SMV in suppressing virus-induced gene silencing (32).…”

Co-infection of Soybean withSoybean mosaic virusandAlfalfa mosaic virusResults in Disease Synergism and Alteration in Accumulation Level of Both Viruses

Co-infection of potyviruses with taxonomically diverse plant viruses results in disease synergism and elevation in the level of accumulation of non-potyviruses involved. In the majority of cases, however, the accumulation level of potyviruses remains essentially unaltered. A few potyviruses, such as Soybean mosaic virus (SMV), naturally infect soybean (Glycine max). Soybean is also a natural host to a number of non-potyviruses including Alfalfa mosaic virus (AMV), which causes mild symptoms often associated with symptom remission. We have now studied the interactions between AMV and SMV on symptom severity and accumulation level of each of the two viruses in soybean. Co-infection of soybean with AMV and SMV was established following mechanical inoculation, irrespective of simultaneous or sequential introduction of the two viruses. In multiple experiments, co-infection of soybean resulted in severe symptoms in doubly infected plants in a strain-independent manner, with enhancement in the level of AMV indicating that the interaction of AMV with SMV is synergistic. Conversely, the level of SMV accumulation was reduced. This suggests that in co-infection with AMV, SMV interacts antagonistically. The observation that co-infection of AMV and SMV results in disease synergism suggests enhancement of potential that AMV may become a serious viral disease of soybean.

“…Soybean mosaic virus (SMV) is an aphid-and seed-transmitted member of the Potyviridae that infects soybean (Glycine max L.) plants and causes significant losses in the amount and quality of seeds harvested (18,20). Since SMV rarely infects alternative host species, seedborne infections are the primary sources of inoculum for SMV infections (18).…”

Soybean mosaic virus (SMV) is an aphid- and seed-transmitted virus that infects soybean (Glycine max) plants and causes significant yield losses. Seed-borne infections are the primary sources of inoculum for SMV infections. The strain specificity of SMV transmission through seed and SMV-induced seed-coat mottling were investigated in field experiments. Six soybean plant introductions (PIs) were inoculated with eight SMV strains and isolates. Transmission of SMV through seed ranged from 0 to 43%, and isolate-by-soybean line interactions occurred in both transmission rates and percentages of mottled seeds. For example, SMV 746 was transmitted through 43% of seed in PI 229324, but was not transmitted through seed of PIs 68522, 68671, or 86449. In contrast, SMV 413 was transmitted through seed from all PIs. SMVs that were transmitted poorly by the Asian soybean aphid, Aphis glycines, also were transmitted poorly through seed. No predicted amino acid sequences within the helper-component protease or coat protein coding regions differentiated the two groups of SMV strains. The loss of aphid and seed transmissibility by repeated mechanical transmission suggests that constant selection pressure is needed to maintain the regions of the SMV genome controlling the two phenotypes from genetic drift and loss of function.
