The aim of the present research was to test the transferability of simple sequence repeat (SSR) markers developed in two Uredinales species to Hemileia vastatrix, coffee rust. The development of efficient techniques for the identification of H. vastatrix isolates is imperative, given the continuous development of new races. The transferability of 25 SSR markers developed in the related Uredinal...

Uromyces fabae on Vicia faba is a model system for obligate biotrophic interactions. Searching for potential effector proteins we investigated the haustorial secretome of U. fabae (biotrophic stage) and compared it with the secretome of in vitro grown infection structures, which represent the pre-biotrophic stage. Using the yeast signal sequence trap method we identified 62 genes encoding prote...

Interactive identification keys for Australian smut fungi (Ustilaginomycotina and Pucciniomycotina, Microbotryales) and rust fungi (Pucciniomycotina, Pucciniales) are available online at http://collections.daff.qld.gov.au. The keys were built using Lucid software, and facilitate the identification of all known Australian smut fungi (317 species in 37 genera) and 100 rust fungi (from approximate...

Caeoma cassiopae sp. nov. (Uredinales) is described on the arctic-alpine shrub Cassiope tetragona. It was found in three locations in the Rocky Mountains of west-central Alberta, and is the first rust reported on the genus Cassiope. The sori resemble the uredinia of species in the genus Chrysomyxa. The host in the Ericaceae also suggests affinity with that genus. However, the spore morphology, ...
