Abstract
Rust fungi are important and destructive plant pathogens. These fungi are obligatory parasites and their life cycle depends on their host plants. This study was conducted to identify these fungi on vegetation in Sistan region based on morphological characteristics of different spore stages including teliospore (shape, color, dimensions, presence or absence of pedicel, number of septum, wall thickness), urdiniospore (shape, color, dimensions, number of germ pores, spore surface ornamentation), and esiospore, if present (shape, color, dimensions, surface ornamentation). With data obtained from morphological and morphometric characteristics, Pileolaria terebinthi, Puccinia aeluropodis, P. bromina, P. calcitrapae, P. carthami, P. cynodontis, P. isiacae, P. polypogonis, Uromyces lineolatus, U. polygoni- avicularis, U. rumicis and were identified. Polypogon monspeliensis and Polypogon maritimus for P. polypogonis, Carthamus lanatus, P. carthami, Bromus gedrosianus, for P. bromina, Centaurea iberica, for P. calcitrapae, U. polygoni- avicularis for Polygong argyrocoleon, Rumex sanguineus for U. rumicis, and Bolboschoenus glaucus for Uromyces lineolatus are new hosts for rust fungi in Iran. On Anagallis arvensis, Cardaria draba, Conyza bonariensis, Cyperus rotundus, Madicago sativa, Taraxacum officinale and Portulaca oleracea, stages of uridiniuum (II) or telium (III) were observed with 2-celled theliospore similar to Puccinia. Except of Cardaria draba and Comyza bonariensis, available literature review showed that no Puccinia species have been reported on above mentioned plants. It also appears that the fungus on Launaea procumbens, is an undescribed new species of Puccinia that needs more examination to confirm it. Aecidium sp. on Euphorbia falcata, aecial stage is observed, seems to be aecial stage of Uryomyces striatus.
