In order to identify the function of Fus3/Kss1-homolog in development and pathogenic process, a StSTE12 gene of Setosphaeria turcica, located downstream in MAPK pathway, was cloned by Genome-walking technology in this reseach. Conservative domain and phylogenetic tree analysis were used to predict possible function of StSte12 by bioinformatics analysis and it was found that StSte12 contained the characteristic of Ste12-like transcription factor and shared highly homologous with other STE12-like genes of pla...
