TAXONOMY OF PUCCINIA STRIIFORMIS s. l. IN IRAN

Abstract

Morphological studies and phylogenetic analysis based on the ITS sequence data showed that there is considerable differences within the <em>Puccinia striiformis</em> complex on members of Triticeae(<em>Triticum </em>and <em>Hordeum</em>), <em>Dactylis glomerata</em> and <em>Poa pratensis</em>. Based on the above molecular and morphological data, we suggest dividing <em>P. striiformis</em> as follows: - <em>P. striiformis</em> s. str. mainly on Triticeae. - <em>P. pseudostriiformis</em> sp. nov. on <em>Poa pratensis</em> (Poeae) - <em>P. striiformoides</em> nom. et stat. nov. on <em>Dactylis glomerata</em> (Poeae)
