Fig. 1From: Population structure of Stemphylium lycopersici associated with leaf spot of tomato in a single fieldA neighbor-joining tree derived from a ClustalW sequence alignment of combined dataset of the ITS and gpd regions of 79 isolates used in this study (SQU pop01–SQU pop79) and other reference Stemphylium species. The distances were determined according to Kimura’s two-parameter model. Bootstrap values (>50 %, 1000 replicates) are positioned alongside the branches. Alternaria alternata was used as an out-groupBack to article page
