Response to “On Seed Transmissibility of Soybean vein necrosisassociated virus in Symptomless Soybean Seedlings”

Soybean Response to Drought and Seed Inoculation

Drought is one of the most important factors that limits N fixation, growth and yield of soybean. 2 The aim of this study was to determine the effects of water stress, starter N application and seed inoculation on yield and yield components of soybean (cv. Williams). The experiment was conducted in 2010 at the Islamshahr town that located in 12 km of South-west of Tehran, the capital of Iran. T...

Seed Transmission of Soybean vein necrosis virus: The First Tospovirus Implicated in Seed Transmission

Soybean vein necrosis virus (SVNV; genus Tospovirus; Family Bunyaviridae) is a negative-sense single-stranded RNA virus that has been detected across the United States and in Ontario, Canada. In 2013, a seed lot of a commercial soybean variety (Glycine max) with a high percentage of discolored, deformed and undersized seed was obtained. A random sample of this seed was planted in a growth room ...

Soybean Mosaic Virus : Infection of Soybean Seed Parts and Seed Transmission

BOWERS, G. R., Jr., and R. M. GOODMAN. 1979. Soybean mosaic virus: Infection of soybean seed parts and seed transmission. Phytopathology 69: 569-572. The presence of soybean mosaic virus (SMV) (Illinois severe isolate) in cotyledons, and embryos from immature seeds of both Midwest and Merit. reproductive plant parts was compared in field-grown, manually inoculated In mature seeds, infectious vi...

Response of two soybean cultivars to moisture stress

Soybean Seed Health

Fig. 3. Wrinkled, white, moldy-appearing seed infected by Phomopsis spp. More than 30 fungi are seed-borne on soybeans. Some, such as Phomopsis spp., the cause of pod and stem blight disease, can severely reduce seed viability (fi g. 1). Others cause quality problems, such as purple seed stain, caused by Cercospora kikuchii, but have less severe effects on viability. However, most fungi that ar...
