Occurrence and Genetic Diversity of Winona-Like Plum pox virus Isolates in Russia

Occurrence and Genetic Diversity of Winona-Like Plum pox virus Isolates in Russia | Plant health | Scoop.it

In studying the distribution and genetic diversity of Plum pox virus (PPV) in Russia, over a dozen new PPV isolates belonging to the strain Winona (PPV-W) were identified by immunocapture reverse-transcription polymerase chain reaction. The data obtained indicate wide dissemination of PPV-W isolate in stone fruit in the European part of the former USSR.

Research examines virus infection's differing effects on plants, insects - PhysOrg.com | Plant health | Scoop.it

Tyler Sharp: Kansas State University plant pathologist Dorith Rotenberg and two students research why virus infection has differing effects on plants and insects.

 

Tomato spotted wilt virus is classified as a persistently propagative virus, which allows the virus to replicate inside the plant and insect. Thrips spreads the disease to plants by feeding on the leafy surfaces. The virus enters through the digestive tract of the insect and then replicates inside epithelial cells, which absorb nutrients.

Distribution of Viruses Infecting Cucurbit Crops and Isolation of Potential New Virus-Like Sequences from Weeds in Oklahoma

Samples were tested against seven viruses, including Cucumber mosaic virus (CMV), Cucumber green mottle mosaic virus (CGMMV), Melon necrotic spot virus (MNSV), Papaya ringspot virus-watermelon strain (PRSV-W, formerly known as Watermelon mosaic virus-1), Squash mosaic virus (SqMV), Watermelon mosaic virus-2 (WMV-2), and Zucchini yellow mosaic virus (ZYMV), using dot-immunobinding assay (DIBA).

New weed host species were found to be infected with PRSV. Some weed species contained possible new viruses.
