centaurea solstitialis/necrosis

Nep1 is an extracellular fungal protein that causes necrosis when applied to many dicotyledonous plants, including invasive weed species. Using transmission electron microscopy, it was determined that application of Nep1 (1.0 micro g mL(-)(1), 0.1% [v/v] Silwet-L77) to Arabidopsis and two invasive

Centaurea solstitialis L. (yellow starthistle), family Asteraceae, an invasive weed in California and the western United States, is targeted for biological control. In the summer of 2003, an epidemic of unknown etiology on dying C. solstitialis plants was observed near Kozani, Greece (40°22'07″N,

Centaurea solstitialis L. (yellow starthistle [YST]), family Asteraceae, an invasive weed in California and the western United States is targeted for biological control. During the spring of 2004, an epidemic of dying YST plants was found near Kozani, Greece (40°22'07″N, 21°52'35″E, 634 m

Phoma exigua Desm. (teleomorph Didymella exigua (Niessl) Sacc.) was isolated from wilted Centaurea solstitialis L. (yellow starthistle) plants displaying necrosis of the crown that were found near Krasnodar, Russia. The fungus was identified using morphological and cultural characteristics (1,2) and

In June and July of 1995, stems of spotted knapweed (Centaurea maculosa) displayed dieback at two field locations near Bozeman, MT. Dieback developed after plant bolting and during apical bud development. Seedlings and plants in the rosette stage were not affected. Symptoms included curling of stems

Macrovipera lebetina obtusa (Dwigubsky, 1832) and Montivipera xanthina (Gray, 1849) (Ottoman Viper) are viper snakes from Viperidae family and found in various locations in Anatolia. Both snakes are responsible for major snake bite cases in Turkey Their venoms cause necrosis, hemorrhage, pain and

Objectives: Natural products originating from plants have been used for many years in the treatment of various diseases, including cancer. Centaurea solstitialis subsp. solstitialis is used in Turkish folk medicine. This study was the first to

The species Asteraceae Centaurea repens (Asteraceae), known as Acroptilon repens, and Talkhe in persian is used in folk medicine as an emetic, anti-epileptic, and anti-malaria herb in many parts of the world but its toxic effects have not determined yet. This study aimed to evaluate the acute and

METHODS Lettuce mosaic virus (LMV) belongs to the genus Potyvirus (type species Potato virus Y) in the family Potyviridae. BACKGROUND The virion is filamentous, flexuous with a length of 750 nm and a width of 15 nm. The particles are made of a genomic RNA of 10 080 nucleotides, covalently linked to
