قارچها ی مولد زنگ (Pucciniales (از منطقه سیستان، جنوب شرق ایران. (Persian)

Rust fungi (Pucciniales) from Sistan region, southeast of Iran. (English)

Rust fungi are belong to biotrophic fungi and are destructive plant pathogens. Due to the lack of consistent research related to rust fungi in the southeast of Iran, especially in the Sistan region, the present research was conducted in order to identify these fungi on vegetation based on the morphological characteristics of teliospore (shape, color, dimensions, presence or absence of pedicel, number of septum, surface ornamentation), urediniospore (shape, color, dimensions, number and position of germ pores, surface ornamentation) and aeciospore (shape, dimensions, surface ornamentation). Based on the results, Melampsora euphorbiae, Puccinia aeluropodis, P. bromina, P. carthami, P. cynodontis, P. isiacae, P. polypogonis, U. polygoni-avicularis, and U. rumicis were reported from Sistan region. Moreover, seven new host species including Bromus gedrosianus, Carthamus lanatus, Polypogon maritimus, Polypogon monspeliensis, Launaea procumbens, Polygonum argyrocoleon, and Rumex sanguineus were recognized for rusts fungi in Iran. The fungus isolated from Launaea procumbens belongs to the genus Puccinia, but its characteristics are different from the previously reported species on this host plant in other countries, including P. butleri and P. launaeae, and more investigations are required to determine the species.
