Abstract
The pathogens causing white blister rusts on members of Brassicaceae, Asteridae and Caryophyllales are classified in three genera including Albugo, Pustula and Wilsoniana (Albuginales, Oomycota), respectively. The current study contributes to our knowledge on Albuginales in Iran. An extensive survey for sampling white blister rust specimens was performed during the 2018-2020 growing season in some regions in Eastern and Northern Iran. Based on morphological and molecular (cox2 and ITS) data. As the result Albugo lepidii on Lepidium sativum, Albugo koreana on Camelina transcaspica, Pustula junggarensis on Takhtajaniantha pusilla, Albugo arenosa on Strigosella africana, A. candida on various hosts, Albugo occidentalis on spinach and Wilsoniana portulacae on Portulaca sp. were identified. This is the first report that morphologically and molecularly verify A. candida on Goldbachia laevigata, Raphanus sativus, Eruca sativa from Iran and on Sinapis arvensis, Savignya parviflora, Isatis leuconeura and Sisymbrium altissimum worldwide. Sisymbrium septulatum and Strigosella grandiflora are reported as Matrix nova for A. candida and A. arenosa, respectively. White blister rust caused by A. candida is reported for the first time on a member of the genus Savignya in Iran. Albugo lepidii, A. koreana and Pustula junggarensis are new records for Iranian mycobiota. Detailed descriptions and illustrations along with phylogenetic placement here are provided for Wilsoniana amaranthi, Wilsoniana portulacae and Albugo occidentalis. Based on morphological and molecular data, two new lineages of Albugo on Lepdium sativum and S. africana are reported and several undescribrd species belonging to the genus Pustula on Lactuca undulata, Senecio spp., Xeranthemum inapertum, Steptorhamphus sp. and Steptorhamphus persicus and from the genus Albugo on Chorispora tenella were identified.
