Disease severities in seven transgenic wheat lines. Transgenic lines and three control wheat varieties were spray-inoculated with a conidial suspension of F. graminearum. Disease severity was calculated as percent of infection in the sprayed heads. Six of the seven transgenic lines showed significant FHB resistance compared to two commercial wheat varieties, Wheaton and ND 2710, and a transgenic Bobwhite control carrying an empty vector. BLFW, transgenic wheat lines; BW, wheat cultivar Bobwhite carrying an empty vector; Wheaton and ND2710, susceptible and tolerant wheat breeding lines, respectively. Error bars represent standard errors of mean. All BLFW lines are significantly different from BW at P < 0.01 by Student's t-tests.
