Salicylic acid prevents Trichoderma harzianum from entering the vascular system of roots
Molecular Plant Pathology - Tập 15 Số 8 - Trang 823-831 - 2014
Ana Alonso‐Ramírez, Jorge Poveda, Ignacio Martín, Rosa Hermosa, Enrique Monte, Carlos Nicolás
SummaryTrichoderma is a soil‐borne fungal genus that includes species with a significant impact on agriculture and industrial processes. Some Trichoderma strains exert beneficial effects in plants through root colonization, although little is known about how this interaction takes place. To better understand this process, the root colonization of wild‐type Arabidopsis and the salicylic acid (SA)‐i... hiện toàn bộ
Expression of coordinately regulated defence response genes and analysis of their role in disease resistance in Medicago truncatula
Molecular Plant Pathology - Tập 12 Số 8 - Trang 786-798 - 2011
Deborah A. Samac, Silvia Peñuela, Judy A. Schnurr, E Nicole Hunt, Dawn Foster‐Hartnett, Kathryn A. VandenBosch, J. Stephen Gantt
SUMMARYMicroarray technology was used to identify the genes associated with disease defence responses in the model legume Medicago truncatula. Transcript profiles from M. truncatula cv. Jemalong genotype A17 leaves inoculated with Colletotrichum trifolii and Erysiphe pisi and roots infected with Phytophthora medicaginis were compared to identify the genes expressed in response to all three pathoge... hiện toàn bộ
Involvement of salicylic acid, ethylene and jasmonic acid signalling pathways in the susceptibility of tomato to Fusarium oxysporum
Molecular Plant Pathology - Tập 18 Số 7 - Trang 1024-1035 - 2017
Xiaotang Di, J. Gomila, Frank L. W. Takken
SummaryPhytohormones, such as salicylic acid (SA), ethylene (ET) and jasmonic acid (JA), play key roles in plant defence following pathogen attack. The involvement of these hormones in susceptibility following Fusarium oxysporum (Fo) infection has mostly been studied in Arabidopsis thaliana. However, Fo causes vascular wilt disease in a broad range of crops, including tomato (Solanum lycopersicum)... hiện toàn bộ
Next‐generation sequencing and metagenomic analysis: a universal diagnostic tool in plant virology
Molecular Plant Pathology - Tập 10 Số 4 - Trang 537-545 - 2009
Ian P. Adams, R. Glover, W. Monger, R. A. Mumford, E. Jackevičienė, M. Navalinskienė, M. Samuitienė, Neil Boonham
SUMMARYA novel, unbiased approach to plant viral disease diagnosis has been developed which requires no a priori knowledge of the host or pathogen. Next‐generation sequencing coupled with metagenomic analysis was used to produce large quantities of cDNA sequence in a model system of tomato infected with Pepino mosaic virus. The method was then applied to a sample of Gomphrena globosa infected with... hiện toàn bộ
Overview and analysis of the polyprotein cleavage sites in the family Potyviridae
Molecular Plant Pathology - Tập 6 Số 4 - Trang 471-487 - 2005
Michael J. Studdert, J. F. Antoniw, Frédéric Beaudoin
SUMMARYThe genomes of plant viruses in the family Potyviridae encode large polyproteins that are cut by virus‐encoded proteases into ten mature proteins. Three different types of protease have been identified, each of which cuts at sites with a distinctive sequence pattern. The experimental evidence for this specificity is reviewed and the cleavage site patterns are compiled for all sequenced spec... hiện toàn bộ
Large‐scale molecular genetic analysis in plant‐pathogenic fungi: a decade of genome‐wide functional analysis
Molecular Plant Pathology - Tập 18 Số 5 - Trang 754-764 - 2017
Thabiso Motaung, Hiromasa Saitoh, Toi J. Tsilo
SummaryPlant‐pathogenic fungi cause diseases to all major crop plants world‐wide and threaten global food security. Underpinning fungal diseases are virulence genes facilitating plant host colonization that often marks pathogenesis and crop failures, as well as an increase in staple food prices. Fungal molecular genetics is therefore the cornerstone to the sustainable prevention of disease outbrea... hiện toàn bộ
Citrus tristeza virus: a pathogen that changed the course of the citrus industry
Molecular Plant Pathology - Tập 9 Số 2 - Trang 251-268 - 2008
Pedro Moreno, Silvia Ambrós, Marı́a R. Albiach-Martı́, J. Guerri, Leandro Peña
SUMMARY Citrus tristeza virus (CTV) (genus Closterovirus, family Closteroviridae) is the causal agent of devastating epidemics that changed the course of the citrus industry. Adapted to replicate in phloem cells of a few species within the family Rutaceae and to transmission by a few aphid species, CTV and citrus probably coevolved for centuries at the site of origin of citrus plants. CTV dispersa... hiện toàn bộ
Arabidopsis HIPP27 is a host susceptibility gene for the beet cyst nematode Heterodera schachtii
Molecular Plant Pathology - Tập 19 Số 8 - Trang 1917-1928 - 2018
Zoran S. Radaković, Muhammad Shahzad Anjam, Elizabeth Escobar, Divykriti Chopra, Javier Cabrera, Ana Cláudia Silva, Carolina Escobar, Mirosław Sobczak, Florian M. W. Grundler, Shahid Siddique
SummarySedentary plant‐parasitic cyst nematodes are obligate biotrophs that infect the roots of their host plant. Their parasitism is based on the modification of root cells to form a hypermetabolic syncytium from which the nematodes draw their nutrients. The aim of this study was to identify nematode susceptibility genes in Arabidopsis thaliana and to characterize their roles in supporting the pa... hiện toàn bộ
The cotton MAPK kinase GhMPK20 negatively regulates resistance to Fusarium oxysporum by mediating the MKK4–MPK20–WRKY40 cascade
Molecular Plant Pathology - Tập 19 Số 7 - Trang 1624-1638 - 2018
Chen Wang, Xiaowen He, Yuzhen Li, Lijun Wang, Xulei Guo, Xingqi Guo
SummaryFusarium wilt is one of the most serious diseases affecting cotton. However, the pathogenesis and mechanism by which Fusarium oxysporum overcomes plant defence responses are unclear. Here, a new group D mitogen‐activated protein kinase (MAPK) gene, GhMPK20, was identified and functionally analysed in cotton. GhMPK20 expression was significantly induced by F. oxysporum. Virus‐induced gene si... hiện toàn bộ
Wheat transcription factor TaWRKY70 is positively involved in high‐temperature seedling plant resistance to Puccinia striiformis f. sp. tritici
Molecular Plant Pathology - Tập 18 Số 5 - Trang 649-661 - 2017
Junjuan Wang, Fei Tao, Fei An, Yiping Zou, Wei Tian, Xianming Chen, Xiangming Xu, Xiaoping Hu
SummaryStripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a devastating disease of wheat (Triticum aestivum) worldwide. Wheat high‐temperature seedling plant (HTSP) resistance to Pst is non‐race‐specific and durable. WRKY transcription factors have been proven to play important roles in plant defence responses to attacks by several pathogens. However, there is no direct evidence ... hiện toàn bộ
