| trichothecene profiling and population genetic analysis of gibberella zeae from barley in north dakota and minnesota. | 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 states. trichothecene biosynthesis gene (tri)-based polymerase chain reaction (pcr) assays and 10 variable n ... | 2011 | 21244225 |
| temporal dynamics and population genetic structure of fusarium graminearum in the upper midwestern united states. | fusarium graminearum sensu stricto causes fusarium head blight (fhb) in wheat and barley, and contaminates grains with several trichothecene mycotoxins, causing destructive yield losses and economic impact in the united states. recently, a f. graminearum strain collected from minnesota (mn) was determined to produce a novel trichothecene toxin, called nx-2. in order to determine the spatial and temporal dynamics of nx-2 producing strains in mn, north dakota (nd) and south dakota (sd), a total of ... | 2014 | 25312860 |
| analysis of deoxynivalenol and deoxynivalenol-3-glucoside in hard red spring wheat inoculated with fusarium graminearum. | deoxynivalenol (don) is a mycotoxin affecting wheat quality. the formation of the "masked" mycotoxin deoxinyvalenol-3-glucoside (d3g) results from a defense mechanism the plant uses for detoxification. both mycotoxins are important from a food safety point of view. the aim of this work was to analyze don and d3g content in inoculated near-isogenic wheat lines grown at two locations in minnesota, usa during three different years. regression analysis showed positive correlation between don content ... | 2013 | 24351715 |
