Population structure and genetic architecture of phenotypic traits in oat (Avena sativa L.) remain relatively under-researched compared to other small grain species. This study explores the historic context of current elite germplasm, including phenotypic and genetic characterization, with a particular focus on identifying under-utilized areas. A diverse panel of cultivated oat accessions was a...

A contribution is made to the rust fungus flora of Argentina: Puccinia baccharidis-boliviensis, P. cordyceps, P. pucarae, and Aecidium hypseocharidicola are described as new species. Cionothrix praelonga, Frommeëlla mexicana var. mexicana, Phakopsora compressa, Prospodium peruvianum, Puccinia amphiospora, P. chaetochloae, P. liabi, P. pappophori, P. sanguinolenta, P. subaquila, Ravenelia havane...

Neotraginops mexicanus n. sp. is described and illustrated based on specimens from Mexico and Belize, representing the second known species for the genus. Additional records for Odinia coronata Sabrosky from Mexico and Nicaragua are provided.

The fungus Cochliobolus victoriae, the causal agent of victoria blight of oats, produces the host-specific toxin victorin. Sensitivity of oats to victorin, and thus susceptibility to the fungus, is controlled by a single dominant gene. This gene is believed to also confer resistance to the crown rust pathogen Puccinia coronata. In the case of victoria blight, the gene has been hypothesized to c...

Crown rust, one of the most destructive diseases oat, regularly occurs worldwide and leads to significant yield losses. The constant evolution Puccinia coronata f. sp. avenae pathogen causes a rapid decline in effectiveness currently used crown rust resistance genes, so new ones are urgently needed. In this study, 39 accessions Avena strigosa Schreb. from ten countries gathered Polish National ...

We describe a 61-year-old man who developed a mild gastrointestinal discomforts including diarrhea associated with feces containing many larvae similar to rhabditiform larvae of Strongyloides stercoralis diagnosed finally as Diploscapter coronata, a free-living nematode. This case is unusual infection in human and there are a few reports of this worm as a real parasite. Microscopically, Diplosc...

Serratula L. and Klasea Cass. are two systematically related genera of the family Asteraceae, which distributed in most Eurasia area used as food colorants traditional medicines a drug. Since 1967, 261 metabolites have been isolated identified from five species 21 species. This review provides information on chemodiversity terpenes, penolics, lipids, other compounds found both their occurrence ...
