Salicylic acid prevents T richoderma harzianum from entering the vascular system of roots
Molecular Plant Pathology - Tập 15 Số 8 - Trang 823-831 - 2014
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...
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
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...
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
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)...
Next‐generation sequencing and metagenomic analysis: a universal diagnostic tool in plant virology
Molecular Plant Pathology - Tập 10 Số 4 - Trang 537-545 - 2009
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...
The target gene of tae‐miR164 , a novel NAC transcription factor from the NAM subfamily, negatively regulates resistance of wheat to stripe rust
Molecular Plant Pathology - Tập 15 Số 3 - Trang 284-296 - 2014
SummarymicroRNA (miRNA) participates in various physiological and biochemical
processes in plants by regulating corresponding target genes. NAC [NAM (no
apical meristem), ATAF (Arabidopsis transcription activation factor) and CUC
(cup‐shaped cotyledon)] transcription factors, usually as the targets of miR164,
play important roles in the regulation of plant development and responses to
abiotic and ...
Overview and analysis of the polyprotein cleavage sites in the family Potyviridae
Molecular Plant Pathology - Tập 6 Số 4 - Trang 471-487 - 2005
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...
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
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...
Citrus tristeza virus: a pathogen that changed the course of the citrus industry
Molecular Plant Pathology - Tập 9 Số 2 - Trang 251-268 - 2008
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...
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
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...
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
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...
