Four different potato cropping systems, designed to address specific management goals of soil conservation, soil improvement, disease suppression, and a status quo standard rotation control, were evaluated for their effects on soilborne diseases of potato and soil microbial community characteristics. The status quo system (SQ) consisted of barley underseeded with red clover followed by po...... hiện toàn bộ
Nivalenol-Type Populations of Fusarium graminearum and F. asiaticum Are Prevalent on Wheat in Southern LouisianaPhytopathology - Tập 101 Số 1 - Trang 124-134 - 2011

U.S. populations of the Fusarium graminearum clade cause head blight on wheat and barley and usually contaminate grain with the trichothecene mycotoxin deoxynivalenol (DON). Recently, however, individual nivalenol (NIV)-type isolates from the United States were described that belonged to either the newly described species F. gerlachii or the genetically distinct Gulf Coast population of F...... hiện toàn bộ
Trichothecene Profiling and Population Genetic Analysis of Gibberella zeae from Barley in North Dakota and MinnesotaPhytopathology - Tập 101 Số 6 - Trang 687-695 - 2011

Gibberella zeae, the principal cause of Fusarium head blight (FHB) of barley, contaminates grains with several mycotoxins, which creates a serious problem for the malting barley industry in the United States, China, and Europe. However, limited studies have been conducted on the trichothecene profiles and population genetic structure of G. zeae isolates collected from barley in the United...... hiện toàn bộ
Population Subdivision of Fusarium graminearum Sensu Stricto in the Upper Midwestern United StatesPhytopathology - Tập 97 Số 11 - Trang 1434-1439 - 2007
Liane Rosewich Gale, Todd J. Ward, Virgilio Balmas, Harold Kistler
A collection of 712 Fusarium graminearum sensu stricto (s.s.) strains, predominantly gathered between 1999 and 2000 from nine states within the United States, was examined for population structure and polymerase chain reaction-based trichothecene type. Most strains belonged to a cohesive genetic population characterized by a 15-acetyldeoxynivalenol (15ADON) trichothecene type. However, us...... hiện toàn bộ
Fusarium Populations on Chinese Barley Show a Dramatic Gradient in Mycotoxin ProfilesPhytopathology - Tập 98 Số 6 - Trang 719-727 - 2008

We report on a large gene bank of Fusarium isolates established by a broad survey conducted in 2005 in which infected barley ears were collected in 23 counties of seven provinces and two municipalities along the Yangtze River in China. In total, 1,894 single spore isolates were obtained. The isolates were characterized at the species level by a newly developed and robust set of diagnostic...... hiện toàn bộ
Population Analysis of Fusarium graminearum from Wheat Fields in Eastern ChinaPhytopathology - Tập 92 Số 12 - Trang 1315-1322 - 2002

Wheat heads showing symptoms of Fusarium head blight were collected from four commercial fields in Zhejiang Province, China, an area where epidemics occur regularly. A total of 225 isolates were subjected to population-level analyses using restriction fragment length polymorphism (RFLP) as markers. Diagnostic RFLP markers established that all isolates belonged to Fusarium graminearum line...... hiện toàn bộ
Genetic Relationships Among Populations of Gibberella zeae from Barley, Wheat, Potato, and Sugar Beet in the Upper Midwest of the United StatesPhytopathology - Tập 98 Số 9 - Trang 969-976 - 2008

Gibberella zeae, a causal agent of Fusarium head blight (FHB) in wheat and barley, is one of the most economically harmful pathogens of cereals in the United States. In recent years, the known host range of G. zeae has also expanded to noncereal crops. However, there is a lack of information on the population genetic structure of G. zeae associated with noncereal crops and across wheat cu...... hiện toàn bộ
