First Report of Tomato Spotted Wilt Virus Isolated from Nasturtium (Tropaeolum majus) with a Serious Leaf Mosaic Disease in China

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 ...

Effect of Gibberellic Acid on the Senescence of Leaf Discs of Nasturtium (Tropaeolum majus).

Aging in leaves is characterized by a decrease in chlorophyll content and an accompanying loss of protein and ribonucleic acid. It is well known that these symptoms of senescence occur at an accelerated rate in excised mature leaves and in leaf discs floated on water. In recent years it has been established that several chemical substances retard the senescence of leaves. Among the compounds wh...

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 ...
