Symptoms caused by soybean vein necrosis virus in North Alabama starting early this year. Observed in multiple fields today. Symptoms appear as yellow to reddish-brown lesions that spread along leaf veins. Yield loss unlikely @CropNetwork #Virus #Soybean @VirologyAPS

Tomato spotted wilt (virus) starting to appear across Alabama. Symptoms include distortion of leaves that turn pale green with purplish spots. Fruit often express ringspots. Plants infected early are stunted & yield poorly. Thrips transmit the virus @VirologyAPS @plantdisease

Tomato spotted wilt virus on tomato. TSWV is spread by thrips & has a wide host range. Symptoms include brown necrotic spots on leaves & petioles, plus twisting of terminals and plant stunting. Best control is to use a variety resistant to TSW @VirologyAPS @plantdisease #Tomato

Tomato spotted wilt virus was a problem for tomato growers in Alabama in 2025. Symptoms include distortion of leaves that turn pale green w/t purplish spots. Fruit often express ringspots. Plants infected early are stunted & yield poorly. Thrips transmit the virus @VirologyAPS

Today, with the @VirologyAPS, I led a field trip in #planthealth2025 where attendees learn about tropical plant production and their pests and diseases. Thanks much to the @uhmanoa personnel who guided the tour !

Read the article led by @MWestOrtiz about a new 🦠 in cotton, which is also integrated in its genome and those of related allotetraploid Gossypium species. @VectorBioSpace

While investigating cotton leafroll dwarf virus in Mississippi, @MWestOrtiz et al. identified a novel virus, cotton virus A (CotVA), in Gossypium plants. @HeckLab_USDA Learn more: doi.org/10.1094/PBIOMES-10-2…
Predicted structural comparisons of cotton virus A (CotVA) open reading frames (ORFs) 2 and 4. A, Top: comparison of AlphaFold 3 (AF3) prediction (turquoise) over the Protein Data Bank crystal structure (3K4T, orange) of the cauliflower mosaic virus (CaMV) virion-associated protein (VAP). Bottom: structural alignment of the AF3 prediction of the CaMV VAP (white) with the AF3 prediction of CotVA ORF4 (colored). B, Same as A but seen from the bottom. C, Comparison of hydrophobicity of CaMV VAP (top), and the predicted hydrophobicity of CotVA ORF4 (bottom). D, Structural alignment of AF3 prediction of Cestrum yellow leaf curling virus (CmYLCV) aphid transmission factor (ATF) (white) to CotVA ORF2 (colored). Confidence in the predictions is measured in the B-factor field (temperature factor) colored from low confidence (cold colors) to high confidence (warm colors).

Easy read on characterization of soybean vein necrosis virus (SVNV) proteins. SVNV is a thrips transmitted virus disease of soybean which causes angular lesions on infected soybean leaves. It does not appear to be economically important at this time @CropNetwork #Soybean #Virus
