... Re-examination of this specimen revealed that it was heavily infected by uredinia and telia of P. striiformoides. During the author's intensive research on the taxonomy of P. graminis in Iran (Abbasi et al. 2002) no D. glomerata specimen infected by P. graminis was found. The plant species is a type host for P. gramimis subsp. ...
Five new species and a new variety of rust fungi (Pucciniales) are described from Iran: Uromyces matinii on Gagea dubia, Uromyces arasbaranensis on Silene italica, Uromyces taleshensis on Colchicum sp., Uromyces kaviriae on Kaviria gossypina, Uromyces iranensis on Hordeum vulgare, and Puccinia calcitrapae var. cirsii-rhizocephali on Cirsium rhizocephalum. Puccinia suaveolens var. karajensis is proposed as a new combination for Puccinia punctiformis var. karajensis on Cirsium arvense. The following new names are made: Peristemma sonchicola and Uromyces liboschitzii. Several new synonyms (syn. nov.) for already-known rust species are proposed. Several new hosts (matrix nov.) for different rust fungi are also reported. Puccinia aristidae on Stipagrostis plumosa, Puccinia hibisci-trioni on Abelmoschus esculentus and Alcea sp., Puccinia marrubii on Marrubium crassidens, and Puccinia tatarica on Mulgedium tataricum are reported as new members for Iranian rust mycobiota. The aecial state of Puccinia kopetdaghensis is newly
described. Identification keys for world-known Uromyces species on the genera Gagea and Silene are provided.

So far, 39 Puccinia species have been reported on Poaceous plants in Iran (Abbasi, unpublished data). ...

Puccinia taeniatheri sp. nov., is newly described from Iran on Taeniatherum asperum (Poaceae) based on morphological study and rDNA ITS sequencing. An identification key for Puccinia species known on the genus Taeniatherum is provided. Re-examination of herbarium material of P. hordei on T. crinitum collected from Iraq revealed that specimen also belongs to P. taeniatheri sp. nov.
... For light microscopy, we used methods mentioned by ABBASI et al. (2002). (Figs 1 & 2). ...
Morphological studies and phylogenetic analysis based on the ITS sequence data showed that there is considerable differences within the Puccinia striiformis complex on members of Triticeae (Triticum and Hordeum), Dactylis glomerata and Poa pratensis. Based on the above molecular and morphological data, we suggest dividing P. striiformis as follows:
- P. striiformis s. str. mainly on Triticeae.
- P. pseudostriiformis sp. nov. on Poa pratensis (Poeae)
- P. striiformoides nom. et stat. nov. on Dactylis glomerata (Poeae)
... Urban's [3] morphological species concept is generally acknowledged as definitive. For example, Abbasi et al. [4] classified specimens according to urediniospore length and also found differences in number of germ pores. Urban further divided P. graminis into two subspecies, P. graminis subsp. ...

(2002) classified specimens according to urediniospore length and also found differences in the number of germ pores. Urban further divides P. graminis into the two subspecies P. graminis subsp. ...
... Morphological analysis of the specimens and their identification to subspecies and variety according to the criteria of Urban (1967) were published previously (Abbasi et al. 2002). Infraspecific classification could not be determined for sequences downloaded from GenBank because the original specimens were not available for examination. ...
... The subspecific taxa delimited mainly using morphological data as proposed by Urban (1967) and Abbasi et al. (2002) are not natural groups and, consequently, do not reflect the phylogeny of the rust. Although information on the subspecific placement of eight specimens was not available, Figs. 1 and 2 provide sufficient evidence for a polyphyletic origin (all three taxa occur in at least two different clades). ...
Puccinia graminis (Uredinales) is an economically important and common host-alternating rust species on Berberidaceae/Poaceae (subfamilies Pooideae and Panicoideae) that has been spread globally by human activities from an unknown center of origin. To evaluate the taxonomic implications, phylogenetic relationships, and distribution/spread of this complex species, we sequenced and cladistically analyzed the ITS1, 5.8S, and ITS2 regions from herbarium specimens on various host plants from Iran (17), Europe (1), and North America (4). The ITS region plus the 5.8S gene ranged from 686 to 701 bp, including the flanking partial sequences of the 18S and 28S rDNA. Our phylogenetic analysis included 54 bp of the 18S sequence, the entire ITS1 + 5.8S + ITS2, and 58 bp of the 28S sequence. A second analysis used only the last 42 bp of ITS1, and all the 5.8S and ITS2, to incorporate data from additional sequences downloaded from GenBank. In addition to variation in sequence length, there was variation in sequence content. The analysis does not support classical morphology-based taxonomic concepts of the P. graminis complex. Also, host range, host taxonomy, and geographic origin provide minor information on taxonomic relationships. Puccinia graminis is most probably monophyletic. Coevolutionary aspects can hardly be discussed because of lack of sequence data from alternate host specimens. The occurrence of unrelated fungal taxa on the same host species suggests that, besides coevolution with the host, host jumps and hybridization may have played an important role in the evolution of P. graminis. From rDNA data we conclude that the pathogen was introduced to North America at least twice independently. For a new taxonomic concept, we think the complex has to be split into at least two species. New morphological features and further features other than sequence data, however, must be checked for taxonomic value first and, if necessary, be considered.
