| evidence for a reversible drought induced shift in the species composition of mycotoxin producing fusarium head blight pathogens isolated from symptomatic wheat heads. | fusarium species are fungal plant pathogens producing toxic secondary metabolites such as deoxynivalenol (don), 15-acetyl-deoxynivalenol (15acdon) and nivalenol (niv). in luxembourg, the fusarium species composition isolated from symptomatic winter wheat heads was dominated by fusarium graminearum sensu stricto strains (genetic 15acdon chemotype) between the years 2009 and 2012, except for 2011, when fusarium culmorum strains (genetic niv chemotype) dominated the pathogen complex. previous repor ... | 2014 | 24859190 |
