Motif based identification of pathogenic patterns for filamentous fungi

摘要

Identifying the unique pathogenic patterns underlying the phytopathogenic fungi is important for plant disease control. This paper presents a novel method for identifying the specific conserved patterns for the pathogenic species. By employing a feature selection technique, the specific patterns that best discriminate the pathogenic species from non-pathogenic ones are identified,which are assumed to be the potential pathogenic patterns that cause pathogenesis. In particular, the specific patterns for Fusarium graminearum (F. graminearum) were found, which can discriminate F.graminearum from other pathogenic species. The identified patterns covered a set of pathogenic genes that have been determined experimentally, which demonstrates the effectiveness of the proposed method.
