Natural population of oat crown rust in Tunisia
Phytopathologia Mediterranea, 2010 Oat crown rust, caused by Puccinia coronata f. sp. avenae, is considered the most widespread and damaging disease of oat (Avena sativa) in Tunisia. The virulence structure of the natural oat rust population in Tunisia was studied in four areas from 2002 ...

Applications of response surface methodology approach to determine the effect of temperature, time of incubation and light conditions on germination and germ tube growth of Puccinia coronata f.sp. avenae urediosopores [PDF]
, 2013 Crown rust caused by Puccinia coronata f.sp. avenae is the most damaging disease on oat. This work analyzed the effects of temperature and illumination regime during different time of incubation on both spore germination and germ tube growth, using both ...

Axenic culture of two rust fungi, Puccinia coronata f. sp. avenae and P. recondita f. sp. tritici.
Japanese Journal of Phytopathology, 1978 Urediniospores of Puccinia coronata f. sp. avenae race 367 and P. recondite f. sp. tritici race 45 were respectively cultured on an artificial medium. Urediniospores free of contaminating microorganisms were obtained by aseptic leaf culture. After the urediniospores were separately seeded on the medium, both rust fungi grew well and then formed white ...

Mapping crown rust resistance at multiple time points in elite oat germplasm
The Plant Genome, Volume 13, Issue 1, March 2020., 2020 Abstract Crown rust, caused by Puccinia coronata f. sp. avenae Erikss., is the most important disease impacting cultivated oat (Avena sativa L.). Genetic resistance is the most desirable management strategy. The genetic architecture of crown rust resistance is not fully understood, and previous mapping investigations have mostly ignored temporal ...

Apoptotic Cell Death is a Common Response to Pathogen Attack in Oats
Molecular Plant-Microbe Interactions, 2002 We have examined the characteristics of cell death induced by pathogen infection in oats with respect to following hallmark apoptotic features: DNA laddering, chromatin condensation, and electron microscopic-bterminal deoxynucleotidyl transferase ...

Characterization of the cytochrome [beta] gene in plant pathogenic, basidiomycetes and consequences for QoI resistance [PDF]
, 2005 Strobilurins are one of the most important classes of agricultural fungicides, which are also known as Qo inhibitors (QoIs) because they inhibit mitochondrial respiration by binding to the Qo (‘Quinone outside’) site of the cytochrome b.
