Purpose Social commerce has brought about a significant transformation in consumer experience due to diverse factors. As result, users often find themselves prone impulsive buying behaviour when exposed such an environment. Prior research was limited demonstrating the expanding influence of celebrities on social media and linkage between engagement impulse context. Furthermore, tendency consumers context celebrity posts yet be validated. This paper aims assess awareness, trust observational...
The development of genetic markers is complex and costly in species with little pre-existing genomic information. Faba bean possesses one the largest least studied genomes among cultivated crop plants no gene-based maps exist. Gene-based orthologous allow chromosomal regions levels synteny to be characterised between species, reveal phylogenetic relationships evolution, enable targeted identification for breeding. In this study codominant cross-species have been deployed produce first...
Summary Fungal effector–host sensitivity gene interactions play a key role in determining the outcome of septoria nodorum blotch disease ( SNB ) caused by Parastagonospora on wheat. The pathosystem is complex and mediated interaction multiple fungal necrotrophic systems. Three effector systems are well characterized this pathosystem; SnToxA– Tsn1 , SnTox1– Snn1 SnTox3– Snn3 . We tested wheat mapping population that segregated for with SN 15, an aggressive P. isolate produces SnToxA, SnTox1...
The fungus Parastagonospora nodorum is the causal agent of Septoria blotch wheat (Triticum aestivum). interaction mediated by multiple fungal necrotrophic effector-dominant host sensitivity gene interactions. three best-characterized effector-sensitivity systems are SnToxA-Tsn1, SnTox1-Snn1 and SnTox3-Snn3. These effector genes highly expressed during early infection, but expression decreases as infection progresses to tissue necrosis sporulation. However, mechanism regulation unknown. We...
We report the first genetic linkage map of white lupin (Lupinus albus L.). An F8 recombinant inbred line population developed from Kiev mutant x P27174 was mapped with 220 amplified fragment length polymorphism and 105 gene-based markers. The consists 28 main groups (LGs) that varied in 22.7 cM to 246.5 spanned a total 2951 cM. There were seven additional pairs 15 unlinked markers, 12.8% markers showed segregation distortion at P < 0.05. Syntenic relationships between Medicago truncatula L....
The fungus Parastagonospora nodorum causes Septoria blotch (SNB) of wheat. A genetically diverse wheat panel was used to dissect the complexity SNB and identify novel sources resistance. is causal agent pathosystem mediated by multiple fungal necrotrophic effector–host sensitivity gene interactions that include SnToxA–Tsn1, SnTox1–Snn1, SnTox3–Snn3. P. strain lacking SnToxA, SnTox1, SnTox3 (toxa13) retained wild-type-like ability infect some modern cultivars, suggesting evidence other...
Parastagonospora nodorum is a necrotrophic fungal pathogen of wheat (Triticum aestivum L.), one the world's most important crops. P. mediates host cell death using proteinaceous effectors, presumably liberating nutrients that allow infection process to continue. The identification effectors has allowed genetic resistance mechanisms be separated into their constituent parts. In nodorum, three have been cloned: SnToxA, SnTox1 and SnTox3. Here, we survey sensitivity all in panel 480 European...
Abstract The fungus Parastagonospora nodorum infects wheat through the use of necrotrophic effector (NE) proteins that cause host-specific tissue necrosis. Zn 2 Cys 6 transcription factor PnPf2 positively regulates NE gene expression and is required for virulence on wheat. Little known about other downstream targets PnPf2. We compared transcriptomes P . wildtype a strain deleted in ( pf2-69 ) during vitro growth host infection to further elucidate signalling. Gene ontology enrichment...
Necrotrophic diseases of wheat cause major losses in most growing areas world. Tan spot (caused by Pyrenophora tritici-repentis) and septoria nodorum blotch (SNB; Parastagonospora nodorum) have been shown to reduce yields 10-20% across entire agri-ecological zones despite the application fungicides a heavy focus over last 30 years on resistance breeding. Efforts breeders improve cultivars has compromised universal finding that was quantitative governed multiple trait loci (QTL). Most QTL had...
Core Ideas First genome‐wide association mapping of adult plant Septoria nodorum blotch resistance. Some resistance loci were shared with seedling loci. Other significant across environments. Resistant haplotypes identified, which can be used for breeding. Parastagonospora is the causal agent leaf (SNB) in wheat ( Triticum aestivum L.). It most important pathogen Norwegian spring wheat. Several quantitative trait (QTL) SNB susceptibility have been identified. these QTL are result underlying...
The fungus Parastagonospora nodorum uses proteinaceous necrotrophic effectors (NEs) to induce tissue necrosis on wheat leaves during infection, leading the symptoms of septoria blotch (SNB). NEs Tox1 and Tox3 possessing dominant susceptibility genes Snn1 Snn3B1/Snn3D1 , respectively. We previously observed that is epistatic expression a quantitative trait locus (QTL) chromosome 2A contributes SNB resistance/susceptibility. significantly higher in Australian strain SN15 compared American SN4....
ToxA is one of the most studied proteinaceous necrotrophic effectors produced by plant pathogens. It has been identified in four pathogens (Pyrenophora tritici-repentis, Parastagonospora nodorum, pseudonodorum [formerly avenaria f. sp. tritici], and Bipolaris sorokiniana) causing leaf spot diseases on cereals worldwide. To date, 24 different haplotypes have identified. Some P. tritici-repentis related species also express ToxB, another small protein effector. We present here a revised...
Septoria nodorum blotch (SNB) is a complex fungal disease of wheat caused by the Dothideomycete pathogen Parastagonospora nodorum. The fungus infects through use necrotrophic effectors (NEs) that cause necrosis on hosts carrying matching dominant susceptibility genes. Western Australia (WA) wheatbelt SNB "hot spot" and experiences as much 50% yield loss under favorable conditions. Consequently, has been major target for breeders in WA many years. In this study, we assembled panel 155 P....
Abstract Background The fungus Parastagonospora nodorum causes septoria blotch (SNB) of wheat ( Triticum aestivum ) and is a model species for necrotrophic plant pathogens. genome assembly reference isolate Sn15 was first reported in 2007. P. infection promoted by its production proteinaceous effectors, three which are characterised – ToxA, Tox1 Tox3. Results A chromosome-scale Australian Sn15, combined long read sequencing, optical mapping manual curation, produced 23 chromosomes with 21...
Orthologous markers transferable between distantly related legume species allow for the rapid generation of genetic maps in where there is little pre-existing genomic or EST information. We are using model Medicago truncatula Gaertn. to develop such legumes importance Australian agriculture. This will enable construction comparative maps, help determine patterns chromosomal evolution family, and characterise syntenic relationships M. cultivated legumes. information can then be used identify...
To date, the only enzyme known to be responsible for hydrolysis of cholesteryl esters and triacylglycerols in lysosome at acidic pH is lysosomal acid lipase (LAL). Lipid malabsorption small intestine (SI), accompanied by macrophage infiltration, one most common pathological features LAL deficiency. However, exact role intestinal lipid metabolism still unknown. We collected three parts SI (duodenum, jejunum, ileum) from mice with a global (LAL KO) or intestine-specific deletion (iLAL...

One hundred thirty-six DArT markers were merged into first composed 220 amplified fragment length polymorphisms (AFLPs) 105 genic markers. The consists 38 groups 441 spans total 2,169 cM, with average interval size 4.6 cM. exhibited good genome...
