Exogenous double‐stranded RNA inhibits the infection physiology of rust fungi to reduce symptoms in planta

Molecular Plant Pathology, Volume 24, Issue 3, Page 191-207, March 2023., 2023
RNA interference genes are present in the Pucciniales and double‐stranded RNA targeting essential genes inhibits urediniospore germination and reduces disease symptoms. Abstract Rust fungi (Pucciniales) are a diverse group of plant pathogens in natural and agricultural systems. They pose ongoing threats to the diversity of native flora and cause annual

Detection of Maternal and Cytoplasmic Effects on Resistance to Zymoseptoria tritici in Durum Wheat

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
Septoria tritici blotch (STB) is a major disease problem of wheat worldwide. To optimize the introgression of resistance genes in elite genotypes throughout traditional or molecular breeding programs, a full understanding of the quantitative inheritance of resistance to Zymoseptoria tritici, plant height (PH), and thousand kernel weight (TKW) is needed.

Oat mega‐environments in Canada

Crop Science, Volume 61, Issue 2, Page 1141-1153, March/April 2021., 2021
Abstract Genotype × environment interaction (GE) is a perennial problem in plant breeding and must be dealt with. Dealing with GE starts with differentiation of repeatable GE from unrepeatable GE in a target region. Repeatable GE can be used by dividing the target region into mega‐environments (MEs) and breeding ME‐specific cultivars, and unrepeatable ...

Pathogenic Variability of Puccinia coronata f. sp. avenae and P. graminis f. sp. avenae on Oat in South Africa [PDF]

Plant Disease, 2001
Although crown rust (caused by Puccinia coronata f. sp. avenae) and stem rust (caused by Puccinia graminis f. sp. avenae) are generally considered to be the most widespread and damaging diseases of oat (Avena spp.) in South Africa, pathogenic variability has never been studied.

Inheritance of resistance to oat crown rust in recombinant inbred lines Herança da resistência à ferrugem da folha da aveia em linhagens recombinantes

Scientia Agricola, 2010
Crown rust is the main disease affecting oats (Avena sativa L.), and genetic resistance has been the chief method utilized to control this disease. A population composed of 135 recombinant inbred lines, F5:6, generated by crossing the oat cultivar UFRGS ...

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 ...
