Teff Rust

Integrating Teff into Livestock Operations

Teff [Eragrostis tef (Zucc.) Trotter] is a relatively new forage crop that is attracting much interest among hay growers in the United States and Utah (Creech, et al., 2012). Teff plants have fine stems, shallow roots and are not frost tolerant. This annual, warm-season grass grows best during the hottest months of the year when cool-season grasses suffer their “summer slump.” Since Teff does n...

Additions to the rust mycobiota of Iran

In the present study, two species of rosaceous rust fungi are reported from Iran. Ochropsora ariae is newly reported for Iranian rust mycobiota. This is the first report of a member of the genus Ochropsora from Iran. Kuehneola uredinis is reported for the second time from Iran since its first report in 1958 under the name K. albida. Pyrus boissieriana</em...

Fighting Asian Soybean Rust

Phakopsora pachyrhizi is a biotrophic fungus provoking SBR disease. SBR poses a major threat to global soybean production. Though several R genes provided soybean immunity to certain P. pachyrhizi races, the pathogen swiftly overcame this resistance. Therefore, fungicides are the only current means to control SBR. However, insensitivity to fungicides is soaring in P. pachyrhizi and, therefore, ...

Biotrophy and rust haustoria

Haustoria produced by biotrophic fungi and Oomycetes are extensions into living host cells. However, they are not truly intracellular. They breach the cell wall only and a newly formed host plasma membrane (the extrahaustorial membrane) surrounds them, resulting in a close association of fungal and plant membranes only separated by a thin fungal wall and an extrahaustorial matrix. The extrahaus...
