Barley Sources of Resistance to the Net Form of Net Blotch (Pyrenophora teres f. teres)

Biology and Life Sciences Forum, 2023
Barley is one of the economically important crop species and the net form of net blotch (NFNB) caused by Pyrenophora teres f. teres has a significant impact on the quantity and quality of grain yield.

High resolution mapping of a novel non-transgressive hybrid susceptibility locus in barley exploited by P. teres f. maculata [PDF]

BMC Plant Biology
Hybrid genotypes can provide significant yield gains over conventional inbred varieties due to heterosis or hybrid vigor. However, hybrids can also display unintended negative attributes or phenotypes such as extreme pathogen susceptibility.

Population Structure of Pyrenophora teres f. teres Barley Pathogens from Different Continents [PDF]

Phytopathology®, 2021
Net form net blotch disease, caused by Pyrenophora teres f. teres, results in significant yield losses to barley industries. Up-to-date knowledge of the genetic diversity and structure of pathogen populations is critical for elucidating the disease epidemiology and unraveling pathogen survival and dispersal mechanisms.

Four Reference Quality Genome Assemblies of Pyrenophora teres f. maculata: A Resource for Studying the Barley Spot Form Net Blotch Interaction

Molecular Plant-Microbe Interactions, 2021
Pyrenophora teres is the causal agent of net blotch, the most devastating foliar disease of barley. In nature, net blotch is seen in two forms, net form net blotch, caused by P. teres f. teres, and spot form net blotch, caused by P. teres f. maculata. To

The Use of an Alternative Differential Set for Determination of Pyrenophora teres f. maculata Pathotypes

Journal of Agricultural Sciences, 2020
Pyrenophora teres f. maculata incites spot form of barley net blotch disease. For determination of Pyrenophora teres f. maculata pathotypes, a differential set consisted of 22 international cultivars and genotypes and a susceptible Turkish barley variety

Expansion and Conservation of Biosynthetic Gene Clusters in Pathogenic Pyrenophora spp.

Toxins, 2020
Pyrenophora is a fungal genus responsible for a number of major cereal diseases. Although fungi produce many specialised or secondary metabolites for defence and interacting with the surrounding environment, the repertoire of specialised metabolites (SM)

Virulence of Icelandic Pyrenophora teres f. teres populations and resistance of Icelandic spring barley lines [PDF]

Journal of Plant Pathology, 2021
AbstractThe causal agent of the barley net blotch disease, Pyrenophora teres, is known for its high level of diversity due to sexual reproduction. Different pathotypes, defined by a virulence combination, even within the same fields are frequently found and virulence between locations can vary considerably.

Turkish barley landraces resistant to net and spot forms of Pyrenophora teres

Phytopathologia Mediterranea, 2017
Pyrenophora teres is an important pathogen of barley. The pathogen has two biotypes: Pyrenophora teres f. teres, which causes the net type of net blotch, and P. teres f. maculata causing the spot type of net blotch.

Pathotypes of Pyrenophora teres on barley in Turkey

Phytopathologia Mediterranea, 2017
Net blotch foliar diseases of barley are important in Turkey, lowering grain yields and quality. There are two forms, the spot form (caused by Pyrenophora teres f. maculata (Ptm)) and the net form (caused by P. teres f. teres (Ptt)).
