Analysis of genetic diversity of <i>Zymoseptoria tritici</i> populations in central and south-eastern Ethiopia.

ABSTRACT: Septoria tritici blotch (STB), caused by the hemibiotrophic fungus Zymoseptoria tritici, is a serious threat to global wheat production, and a major bottleneck to wheat production in Ethiopia. Accurate identification and analysis of the pathogen's genetic structure helps to develop robust STB management strategies. This study aimed at molecular identification and genetic structure analysis of 200 isolates of Z. tritici representing six populations in central and south-eastern regions of Ethiopia. A total of 165 isolates were confirmed by Sanger sequencing of the internal transcribed spacer (ITS) region of nuclear DNA (rDNA) region. The pathogen's genetic structure was further examined using 12 simple sequence repeat (SSR) markers. The microsatellite markers were highly polymo
