Project description:Verticillium dahliae is a soil-borne fungus with a broad host range, including the model plants Nicotiana benthamiana and Arabidopsis thaliana. The plant immunity can be activated by Vd-derived patterns while V. dahliae secreted effectors. We report here the RNAseq analyses of samples from N. benthamiana infected by V. dahliae strains 592 and 171 at different time points. The data showed dynamic expression patterns of genes not only from plant defense signaling but also plant developmental signaling.

Project description:Verticillium dahliae is a soil-borne vascular pathogen that causes severe wilt symptoms in a wide range of plants. Co-culture of the fungus with Arabidopsis roots for 24 hours induces many changes in the gene expression profiles of both partners, even before defense-related phytohormone levels are induced in the plant. Both partners reprogram sugar and amino acid metabolism, activate genes for signal perception and transduction, and induce defense and stress responsive genes. Furthermore, analysis of Arabidopsis expression profiles suggests a redirection from growth to defense. The plant and fungal genes that rapidly respond to the presence of the partner might be crucial for early recognition steps and the future development of the interaction. Thus they are potential targets for the control of V. dahliae-induced wilt diseases.

Project description:Phytophthora cinnamomi is a devastating soil-borne oomycete with a very broad host range however there remains a major gap in the understanding of plant resistance responses to the pathogen, furthermore, necrotrophic plant-pathogen interactions, particularly those of root pathogens, remain poorly understood. Zea mays exhibits non-host resistance to the pathogen and has been well characterised as a model species. Using the maize Affymetrix GeneChip array we conducted genome-wide gene expression profiling to elucidate the defence genes and pathways which are induced in the root tissue of a resistant plant species to the pathogen.

Project description:Communication between interacting organisms via bioactive molecules is widespread in nature and plays key roles in diverse biological processes. Small RNAs (sRNAs) can travel between host plants and filamentous pathogens to trigger trans-kingdom RNA interference (RNAi) in recipient cells and modulate plant defense and pathogen virulence. However, how trans-kingdom RNAi is regulated has rarely been reported. Here, we show that the secretory protein VdSSR1 (secretory silencing repressor 1) from Verticillium dahliae, a soil-borne phytopathogenic fungus that causes wilt diseases in a wide range of plant hosts, is required for fungal virulence in plants through the suppression of trans-kingdom RNAi.

Project description:The soil-borne ascomycete Verticillium dahliae which causes wilt disease in many important crops results a severe reduction in crop yield and quality. During infection, the V.dahliae will secrete a lot of secondary metabolites which act as toxic factors to promote the infection process. However, the mechanism underlying how V.dahliae secondary metabolites regulate cotton infection remains largely unexplored. BRE1 is a highly conserved ubiquitin ligase (E3) enzymes and regulate expression of specific genes related to the production of secondary metabolites. To get an insight into the genes regulated by VdBre1, the comparative transcriptomic analysis was conducted between VdBre1 deletion mutant and the wild type V592. The conidia of wilde type and mutant were collected and total RNA was extracted using fungal RNA kit, sequencing was performed on an BGISEQ-500 platform.

Project description:Plant roots secrete secondary metabolites to sense the enviroment around them. Among them, terpenes play a prominent role. Terpenes can have either fungistatic or fungicide action. However, their exact role in plant-host interactions is not fully understood. Verticillium longisporum is a soilborne pathogen causing disease in Brasicacae plants. In this project we investigated the transcriptomic changes of this species upon exposure to the β-pinene monoterpene in different time points 0hpi, 8hpi, 24hpi and 24hpi.

Project description:Tandem Mass Tag (TMT)-based quantitative proteomic analysis of tomato soil borne pathogen Fusarium oxysporum f. sp. radicis-lycopersici growth, and metabolism when treated with plant natural volatile organic compounds linalool. The Forl strain was cultured on PDA supplied with 0.8 mL/L linalool for 6 days at 25°C. The fungal strain on PDA supplied with only 0.1% Tween80 was cultured as the control. Three biological replicates were established for each treatment.

Project description:Understanding the mechanisms underlying the establishment of invasive plants is critical in community ecology. According to a widely accepted theory, plant-soil-microbe interactions mediate the effects of invasive plants on native species, thereby affecting invasion success. However, the roles and molecular mechanisms associated with such microbes remain elusive. Using high throughput sequencing and a functional gene microarray, we found that soil taxonomic and functional microbial communities in plots dominated by Ageratina adenophora developed to benefit the invasive plant. There were increases in nitrogen-fixing bacteria and labile carbon degraders, as well as soil-borne pathogens in bulk soil, which potentially suppressed native plant growth. Meanwhile, there was an increase of microbial antagonism in the A. adenophora rhizosphere, which could inhibit pathogenicity against plant invader. These results suggest that the invasive plant A. adenophora establishes a self-reinforcing soil environment by changing the soil microbial community. It could be defined as a ‘bodyguard/mercenary army’ strategy for invasive plants, which has important insights for the mitigation of plant invasion.

Project description:Cropping soils vary in extent of natural suppression of soil-borne plant diseases. However, it is unknown whether similar variation occurs across pastoral agricultural systems. We examined soil microbial community properties known to be associated with disease suppression across 50 pastoral fields varying in management intensity. The composition and abundance of the disease-suppressive community were assessed from both taxonomic and functional perspectives.

Project description:As a broad group, hemibiotrophic pathogens cause significant losses within agriculture threatening the sustainability of food systems globally. The complex manner in which these microbes colonize their hosts, including an initial biotrophic phase of colonization followed by a biotrophic-to-necrotrophic switch (BNS) phase and ending with a necrotrophic mode of nutritional acquisition, renders their management more complex than pathogens which display a single nutritional strategy. Within model plant systems, typically each of these phases is characterized by both common and discrete transcriptional responses as the host modulates physiological processes in concert with changes in pathogen biology. Plant hormones also play an important role in these stages with classic models showing that salicylic acid accumulates during the biotrophic phase and jasmonic acid/ethylene responses occur during the necrotrophic phase. In this study, we use the interaction between the hemibiotroph Phytophthora medicaginis and the roots of its host Cicer arietinum (chickpea) to define the duration of the different life stages of P. medicaginis during the pathogenesis of chickpea. Using transcriptional profiling across all three stages of infection we demonstrate that chickpea displayed some similarities in response to P. medicaginis as has been previously documented in other model plant-pathogen hemibiotrophic interactions. However, our transcriptomic results suggest that chickpea does not conform to the phytohormone response model observed in leaf colonization, nor to that observed for roots of other plant species being colonised by soil-borne hemibiotrophs. We confirm these findings using targeted quantification of salicylic acid and jasmonic acid. The findings from this study demonstrate that a wider spectrum of plant species should be investigated in future to understand the physiological changes in plants during the different stages of colonization by hemibiotrophic soil-borne pathogens before we can better manage these economically important microbes in agronomically relevant conditions.
