- Abstract
The genus Xenodidymellaincludes eight species that are mainly plant pathogens causing different diseases worldwide. During a survey on plant diseases in Khuzestan province in southwestern Iran, seven isolates of Xenodidymellawere obtained from symptomatic plants, including Brassica oleraceavar. capitata, Callistemon citrinus, Corchorus olitorius, Coriandrum sativum, Glycyrrhiza lepidota, and Ziziphus mauritiana. A multi-locus phylogenetic analysis based on the internal transcribed spacer regions 1 and 2 including the 5.8S nuclear ribosomal DNA (ITS), partial β-tubulin (tub2), and RNA polymerase II second largest subunit (rpb2), combined with morphology, was used to identify the isolates. Accordingly, the novel species Xenodidymella iranicais introduced and characterized here along with five new hosts for X. glycyrrhizicola. In pathogenicity tests, X. iranicaand three strains of X. glycyrrhizicolaare known as pathogenic on host plants from where they were originally isolated.
