Technical Abstract: Gibberella zeae (anamorph: Fusarium graminearum) causes head scab or head blight of wheat, barley, and oats, and foot and crown rot of corn. Recent scab outbreaks in Asia, Canada, Europe, South America and the United States highlight the increased threat this disease poses to food supplies worldwide. A better understanding of the biology of the scab organism is warranted to develop new control strategies. Our long term goals are: (1) to understand the genetic basis for inoculum development, mycotoxin production, and pathogenicity and (2) to use genomics to develop a biology- based control program for scab, using the genomics programs of wheat and corn to enhance this program. We have sequenced and analyzed a cohort of over 12,000 ESTs from 3 cDNA libraries representing different culture conditions and developmental stages. We will present the functional categorization of the genes in these libraries and a comparative analysis of gene expression.
