Septoria nodorum blotch (SNB), a disease caused by the necrotrophic fungal pathogen Parastagonospora nodorum, is threat to wheat (Triticum aestivum) production worldwide. Multiple inverse gene-for-gene interactions involving recognition of effectors (NEs) sensitivity genes play major roles in causing SNB. One interaction involves gene Snn3 and P. NE SnTox3. Here, we used map-based strategy clone Snn3-D1 from Aegilops tauschii, D-genome progenitor common wheat. contained protein kinase sperm...
The wheat-Parastagonospora nodorum pathosystem has emerged as a model system for plant-necrotrophic fungal pathogen interactions. In this system, necrotrophic effectors (NEs) are recognized by specific host genes in an inverse gene-for-gene manner to induce programmed cell death (PCD) and other responses, which leads disease. We previously cloned wheat gene (Snn3-D1) encoding protein kinase (PK) major sperm (MSP) domains that recognizes the P. NE SnTox3. Here, we identified Snn3-D1 homoeolog...
<title>Abstract</title> The wheat <italic>Tsn1</italic> gene recognizes the necrotrophic effector ToxA, which is produced by three different fungal pathogens. A compatible <italic>Tsn1</italic>-ToxA interaction leads to host-induced responses that result in development of disease. Therefore, marker-assisted elimination functional alleles an effective strategy for disease resistant varieties. To develop such markers, available genome assemblies were used compare and transposable element...
ABSTRACT Fusarium head blight (FHB) is a destructive wheat ( Triticum aestivum L.) disease of global importance. The widely used dwarfing allele Rht‐D1b has recently been shown to compromise FHB resistance. objectives this study were investigate the impact in segregating population with major resistance quantitative trait loci (QTL) derived from ‘Sumai‐3’ and Nobeokabozu, determine how many QTL are needed counteract its negative effect. was evaluated four field trials spray inoculation two...
The USDA–ARS National Small Grains Collection (NSGC) maintains germplasm representing global diversity of small grains and their wild relatives. To evaluate the utility NSGC durum wheat ( Triticum turgidum L. ssp. ) accessions, we assessed genetic linkage disequilibrium (LD) patterns in a core subset containing 429 lines with spring growth habit originating from 64 countries worldwide. Genetic estimated using single‐nucleotide polymorphism (SNP) markers showed considerable captured this...
Tan spot, caused by the necrotrophic fungal pathogen Pyrenophora tritici-repentis (Ptr), is an important disease of durum and common wheat worldwide. Compared with wheat, less known about genetics molecular basis tan spot resistance in wheat. We evaluated 510 lines from Global Durum Wheat Panel (GDP) for sensitivity to effectors (NEs) Ptr ToxA ToxB reaction isolates representing races 1 5. Overall, susceptible were most prevalent South Asia, Middle East, North Africa. Genome-wide association...
Abstract Septoria nodorum blotch (SNB), caused by Parastagonospora nodorum, is a disease of durum and common wheat initiated the recognition pathogen-produced necrotrophic effectors (NEs) specific genes. The gene Snn1 encodes wall-associated kinase that directly interacts with NE SnTox1 leading to development SNB. Here, sequence analysis from 114 accessions including diploid, tetraploid hexaploid species revealed some lines possess two copies (designated Snn1-B1 Snn1-B2 ) approximately 120...
SUMMARY Septoria nodorum blotch (SNB), caused by Parastagonospora nodorum, is a disease of durum and common wheat initiated the recognition pathogen‐produced necrotrophic effectors (NEs) specific genes. The gene Snn1 was previously cloned, it encodes wall‐associated kinase that directly interacts with NE SnTox1 leading to programmed cell death ultimately development SNB. Here, sequence analysis from 114 accessions including diploid, tetraploid, hexaploid species revealed some lines possess...
Abstract Septoria nodorum blotch (SNB) and tan spot, caused by the necrotrophic fungal pathogens Parastagonospora Pyrenophora tritici-repentis , respectively, often occur together as a leaf spotting disease complex on wheat ( Triticum aestivum L.). Both produce effectors (NEs) that contribute to development of disease. Here, genome-wide association analysis diverse panel 264 winter lines revealed novel loci chromosomes 5A 5B associated with sensitivity NEs SnTox3 SnTox5 in addition known...
Abstract Drought stress is one of the major abiotic factors that significantly reduces wheat grain yield. Improving drought tolerance a challenge plant breeders are facing nowadays. In this study, our goal was to identify quantitative trait loci (QTL) in Plainsman V./Cappelle Desprez doubled haploid (DH) population under induced as decreased irrigation (ds) and well-watered (ww) conditions glasshouse. total, 54 QTL were detected across three years two water regimes linked 10...
