Rusts are economically important diseases of switchgrass (Panicum virgatum) and other Paniceae grasses. Phylogenetic analyses based on sequences of the nuc rDNA 5.8S internal transcribed spacer 2 region (ITS2), partial 28S region, and intergenic spacer region (IGS) of nuc rDNA showed that species of rust fungi infecting switchgrass are closely related ...

SummaryRust fungi are important components of ecological communities and in ecosystem function. Their unique life strategies as biotrophic pathogens with complicated life cycles could make them vulnerable to global environmental change. While there are gaps in our knowledge, especially in natural plant–rust systems, this review of the exposure of rust ...

Rust fungi (Basidiomycota; Order Uredinales) belong to the largest groups of fungi, with more than 6000 recognized species. Rust diseases have accompanied human history from the beginning of agriculture in the Fertile Crescent and Central America, by threatening the health and productivity of the earliest cereal (wheat, barley, maize) and legume (pea ...

Phylogenetics and Phylogenomics of Rust Fungi
2017Rust fungi (Pucciniales) are the most speciose and the most complex group of plant pathogens. Historically, rust taxonomy was largely influenced by host and phenotypic characters, which are potentially plastic. Molecular systematic studies suggest that the extant diversity of this group was largely shaped by host jumps and subsequent shifts.

Aecidium fragiforme &A. balansae, parasites ofAgathis spp. in the Malay Archipelago and New Caledonia, respectively, are similar but separate species. They differ from all other confier-infecting rust fungi in having intra-epidermal spermogonia, and from nearly all others in having cupulate aecia.Caeoma sanctae-crucis onAraucaria in Chile has unique ...

Limb rust is a killing disease of hard pines caused by Peridermium spp. Study of tissue sections shows that growth of limb rust fungi differs from growth of other plant rusts: (1) longitudinal spread is mainly by hyphal growth within host tracheids; (2) hyphae grow radially in mature xylem, deep in host sapwood; (3) in larger stems mycelia avoid ...

Bulletin of the Torrey Botanical Club, 1940
The writer has been interested in the Uredinales ever since he came to Alaska 25 years ago. During the earlier years specimens were sent to Dr. J. C. Arthur at Purdue University for determination, and reports of these were included in his work on the group in North Aminerican Flora, Vol. 7, and his Manual of the Rusts of United States and' Canada.

Some Scottish mountain rust fungi
Transactions of the British Mycological Society, 1953Infection experiments were performed with Melampsora epitea from Saxifraga hypnoides , and with Melampsora epitea var. reticulata from Saxifraga aizoides to ascertain the uredo-, and the teleutospore hosts. The experiments showed that the rust on S. hypnoides infects Salix herbacea and some of its hybrids.
