Tomato Production under Mesh Reduces Crop Loss to Tomato Spotted Wilt Virus in Some Cultivars

Tomato spotted wilt virus

Tomato spotted wilt virus.

Growers in Georgia first noted problems in their peppers and onions during the last week of March 1989. Thrips populations combined with further field symptoms and the verification of the disease triggered a massive insecticide spray program in Georgia. Monitor was first used in early May followed by combinations of Orthene, Cygon and Thiodan. Most fields had less than 1% infection prompting a ...

Tomato Spotted Wilt Virus on Peanuts

I the last decade, tomato spotted wilt virus (TSWV) has become widely distributed across Alabama on many field, vegetable, and floral crops. About 300 plant species, mainly broadleafs, are hosts of TSWV. In addition to peanut, other important crops grown in the Southeast that are susceptible to this virus include tomato, pepper, potato, cucurbits, lettuce, eggplant, and tobacco. Chrysanthemum, ...

A System to Explore Tomato Spotted Wilt Virus Gene Function

Tomato spotted wilt virus (TSWV) has one negative sense (L) and two ambisense (M and S) RNAs. The lack of a tractable TSWV reverse genetics system has impeded direct demonstration of gene function and prevented the usual types of pathogen characterization. The TSWV NSm (non-structural) protein has been presumed to be the viral movement protein (MP) based on a few lines of indirect evidence. We ...

Tomato spotted wilt virus particle morphogenesis in plant cells.

A model for the maturation of tomato spotted wilt virus (TSWV) particles is proposed, mainly based on results with a protoplast infection system, in which the chronology of different maturation events could be determined. By using specific monoclonal and polyclonal antisera in immunofluorescence and electron microscopy, the site of TSWV particle morphogenesis was determined to be the Golgi syst...
