Outline of Final Research Achievements

ProA is a transcription factor necessary for maintaining a symbiotic relationship with the host grass plants in Epichloe festucae. To identify ProA-binding sequences across the genome, we used a gSELEX method and collected the genomic DNA pools after gSELEX selection. The genomic DNA pools were sequenced using a Miseq platform. The direct target sequences were identified by mapping the reads to a reference sequence. Functional analysis of the potential new targets for ProA revealed 4 genes are encoding the proteins that contribute to maintaining the proper symbiotic interaction between E. festucae and the host ryegrass plants.
