The fungal pathogen Bipolaris sorokiniana (Sacc.) Shoem. (teleomorph: Cochliobolus sativus (Ito &Kurib.) Drechs. ex Dastur) is present in all cereal growing regions with warm and humid conditions, but its importance is also increasing in the Americas and Europe (Gupta et al., 2018). Bipolaris sorokiniana is the causal agent of a number of diseases such as common root rot, seedling blight, black point and spot blotch (Kumar et al., 2002). This hemi-biotrophic fungus has a wide host range and is pathogenic on a number of plant species, such as bread and durum wheat (Triticum aestivum and T. durum), barley (Hordeum vulgare), triticale (x Triticosecale), rye (Secale cereal), maize (Zea mays), rice (Oryza sativa), pearl and fox millet (Pennisetum glaucum and Setaria italica) and several other wild grasses (Acharya, Dutta, & Pradhan, 2011; Gupta et al., 2018; Kumar et al., 2002). First reported in 1914, it became an important pathogen mainly with the beginning of the Green Revolution when semi-dwarf wheat cultivars turned out to be highly susceptible

“…The Rpt5 locus has been reported by multiple studies and is considered to be a complex locus that is highly important in the P. teres f. teres– barley interaction (Abu Qamar et al , ; Adawy et al , ; Adhikari et al , ; Cakir et al , , ; Dontsova et al , ; Emebiri et al , ; Friesen et al , ; Grewal et al , , ; Gupta et al , , ; Koladia et al , ; Liu et al , ; Ma et al , ; Manninen et al , , ; Martin et al , ; Molnar et al , ; Novakazi et al , ; O’Boyle et al , ; Raman et al , ; Rau et al , ; Richards et al , ; Richter et al , ; Rozanova et al , ; Spaner et al , ; St. Pierre et al , ; Steffenson et al , ; Wonneberger et al , , ).

“…A total of seven conventional genome‐wide association studies (GWAS) have been performed to investigate P. teres f. teres resistance in barley (Adhikari et al , ; Amezrou et al , ; Daba et al , ; Novakazi et al , ; Richards et al , ; Rozanova et al , ; Wonneberger et al , ). Investigation of resistance to a set of diverse global isolates was performed on the Barley Core Collection (Muñoz‐Amatriaín et al , ; Richards et al , ), Nordic Barley Panel (Wonneberger et al , ), ICARDA AM‐2014 Panel (Amezrou et al , ), Ethiopian, ICARDA and NDSU Barley Panel (Daba et al , ), Siberian Barley Panel (Rozanova et al , ), Ethiopian and Eritrean Barley Collection (Adhikari et al , ) and Vavilov Research Institute Collection (Novakazi et al , ). Between 7 and 31 unique genomic loci were identified in each GWAS (Fig.…”

Summary Pyrenophora teres f. teres and P. teres f. maculata are significant pathogens that cause net blotch of barley. An increased number of loci involved in P. teres resistance or susceptibility responses of barley as well as interacting P. teres virulence effector loci have recently been identified through biparental and association mapping studies of both the pathogen and host. Characterization of the resistance/susceptibility loci in the host and the interacting effector loci in the pathogen will provide a path for targeted gene validation for better‐informed release of resistant barley cultivars. This review assembles concise consensus maps for all loci published for both the host and pathogen, providing a useful resource for the community to be used in pathogen characterization and barley breeding for resistance to both forms of P. teres.

“…At present, researches on peanut web blotch mainly focus on the classification status of the pathogen asexual generation, the pathogen molecular biology, chemical control and epidemic rules [6][7][8][9][14][15]. A similar disease called net blotch, caused by Pyrenophora teres is also one of the major diseases in barley [19]. Many studies have identified a large region of chromosome 6H responsible for resistance to net blotch in barley [20][21][22][23] and a region in chromosome 3H harbors two predicted genes from the NBS-LRR gene family [24].…”

Background: Web blotch is one of the most important foliar diseases worldwide in peanut (Arachis hypogaea L.). The identification of quantitative trait loci (QTLs) for peanut web blotch resistance represents the basis for gene mining and the application of molecular breeding technologies.Results: In this study, a peanut recombinant inbred line (RIL) population was used to map QTLs for web blotch resistance based on high-throughput genome-wide sequencing. Frequency distributions of disease grade and disease index in five environments indicated wide phenotypic variations in response to web blotch among RILs. A high-density genetic map was constructed, containing 3,634 bin markers distributed on 20 peanut linkage groups (LGs) with an average genetic distance of 0.5 cM. In total, eight QTLs were detected for peanut web blotch resistance in at least two environments, explaining from 2.8% to 15.1% of phenotypic variance. Two major QTLs qWBRA04 and qWBRA14 were detected in all five environments and were linked to 40 candidate genes encoding nucleotide-binding site leucine-rich repeat (NBS-LRR) or other proteins related to disease resistances. Conclusions: The results of this study provide a basis for breeding peanut cultivars with web blotch resistance.
