Project description:The soilborne fungus, Verticillium dahliae, causes Verticillium wilt disease in plants. Verticillium wilt is difficult to control since V. dahliae is capable of persisting in the soil for 10 to15 years as melanized microsclerotia, rendering crop rotation strategies for disease control ineffective. Microsclerotia of V. dahliae overwinter and germinate to produce infectious hyphae that give rise to primary infections. Consequentially, microsclerotia formation, maintenance, and germination are critically important processes in the disease cycle of V. dahliae.

Project description:Verticillium transcription activator of adhesion 3 (Vta3) is required for plant root colonization and pathogenicity of the soil-borne vascular fungus Verticillium dahliae [Bui et al., 2018]. In this study, we discovered that Vta3 contributes to the virulence of V. dahliae on tomato plants by promoting ELV1 gene expression, which is not necessary for vegetative growth or production of conidiospores. Gene expression of the transcription factor Mtf1 is reduced in the presence of an intact VTA3 gene. The presence of an intact MTF1 gene triggers the expression of fungal effector genes and plant immune responses (transcription of tomato pathogenesis-related protein genes, and levels of pipecolic and salicylic acids functioning in tomato defense signaling against (hemi-) biotrophic pathogens), and is required for disease symptoms similar to those seen in tomato plants infected by the V. dahliae wild-type. Mtf1 promotes the formation of resting structures at the end of the infection cycle, which allows the fungus to survive in the soil and later to re-infect host plants. Protein pull-downs were performed with GFP-fused Vta3 to investigate whether there is evidence for a direct interaction of the regulators Vta3 and Mtf1. In this study, ribosomal proteins predominantly co-enriched with Vta3, and our data set did not give evidence that Mtf1 directly interacts with Vta3.

Project description:Verticillium dahliae is a soilborne fungus that causes wilt disease in plants. The microsclerotia of V. dahliae produce infectious hyphae that give rise to primary infections. In this study, RNA-seq libraries were prepared from microsclerotia (MS)-producing cultures of V. dahliae (ave = 52.23 million reads), and those not producing microsclerotia (NoMS, ave = 50.58 million reads) and analyzed for differential gene expression.

Project description:Verticillium dahliae Kleb., a soil-borne fungus that colonizes vascular tissues, induces wilting, chlorosis and early senescence in potato. Difference in senescence timing found in two diploid potato clones, 07506-01 and 12120-03, was studied and genetic variation in response to V. dahliae infection was identified as a causal factor. The clone, 07506-01, was infected with V. dahliae but did not develop symptoms, indicating tolerance to the pathogen. The other diploid clone, 12120-03 had low levels of pathogen with infection and moderate symptoms indicating partial resistance. 07506-01 was found to carry two susceptible alleles of the Ve2 gene and 12120-03 carried one Ve2 resistant and one susceptible allele. Infected leaves of the two clones were compared using gene expression profiling with the Potato Oligonucleotide Chip Initiative (POCI) microrarray. The results provide further evidence for differences in response of the two clones to infection with V. dahliae. Chlorophyll biosynthesis was higher in the tolerant 07506-01 compared to partially resistant 12120-03. On the other hand, expression of fungal defense genes, Ve resistance genes and defense phytohormone biosynthetic enzyme genes was decreased in 07506-01 compared to 12120-03 suggesting defense responses were suppressed in tolerance compared to resistance. Transcription factor gene expression differences pointed to the WRKY family as potential regulators of V. dahliae responses in potato.

Project description:Verticillium wilt which is caused by Verticillium dahliae causes massive annual losses of cotton yield. Control by conventional mechanisms is not possible due to wide host range and longevity of dormant fungi in the soil in case of absence of a suitable host. Plants have developed various mechanisms to boost their immunity against various diseases, and one of which is through the induction of various genes. In this research work, carried out of RNA sequencing and identified the members of the ABC genes are critical in enhancing resistance to V. dahliae infection. A total of 166 ABC genes were identified in Gossypium raimondii with varying physiochemical properties. A novel ABC gene, Gorai.007G244600 was found to be highly upregulated, its homolog in the tetraploid cotton Gh_D11G3432, was then silenced through virus induced gene silencing (VIGS) in tetraploid cotton, the mutant cotton seedlings that have the ability to tolerate V. dahliae infection were significantly reduced. Evaluation of oxidant, hydrogen peroxide (H2O2) and malondialdehyde (MDA) were found to have increased levels in the leaves of the mutant compared to the wild types. In addition, antioxidant enzymes, peroxidase (POD), catalase (CAT) and superoxide dismutase (SOD) concentration levels were significantly reduced in the mutant cotton compared to the wild types. Moreover, expression levels of the biotic stress genes, cotton polyamine oxidase (GhPAO), cotton ribosomal protein L18(GhRPL18) and cotton polygalacturonase-inhibiting protein-1 (GhPGIP1) were all downregulated in the mutant but highly upregulated in the wild cotton tissues. The outcome of this research has shown that ABC genes could be playing an important role in enhancing immunity of cotton to V. dahliae infection and can be explored in developing more resilient cotton genotypes with improved resistance to V. dahliae infection.

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 wilt of potato caused by Verticillium dahliae, also called potato early dying disease, is an important factor limiting potato production in the world. Currently, the poor understanding of the pathogenic mechanism of Verticillium dahliae has led to increasingly severe challenges in the effective control of Verticillium wilt. Many studies have shown that pigment biosynthesis related proteins are virulence factors of Verticillium dahliae, while the regulatory mechanisms are still unknown. In order to elucidate the pathogenic mechanism regulated by the virulence related pigment biosynthesis protein Vayg1 in Verticillium dahliae, proteomic analysis will be used to judge the Vayg1 deletion mutant and the wild-type strain during the infection of potato to explore the Vayg1 involved pathogenic protein network, aiming to identify and understand relevant pathogenic pathways to provide an important support for deeper understanding of the pathogenic mechanism of the pathogen. The key proteins related to virulence and molecular networks that will be obtained in this study could provide new targets for the control of Verticillium wilt and new insights for the improvement of disease management.
