Secreted small cysteine-rich proteins (SCPs) play a critical role in modulating host immunity in plant-pathogen interactions. Bioinformatic analyses showed that the fungal pathogen Verticillium dahliae encodes more than 100 VdSCPs, but their roles in host-pathogen interactions have not been fully characterized. Transient expression of 123 VdSCP-encoding genes in Nicotiana benthamiana identified three candidate genes involved in host-pathogen interactions.

Improving genetic resistance is a preferred method to manage Verticillium wilt of cotton and other hosts. Identifying host resistance is difficult because of the dearth of resistance genes against this pathogen. Previously, a novel candidate gene involved in Verticillium wilt resistance was identified by a genome-wide association study using a panel of Gossypium hirsutum accessions.

Article Synopsis
  • Verticillium dahliae is a pathogen causing wilts in plants, leading to severe defoliation, with its underlying mechanisms still not fully understood.
  • Research involved various methods like genome sequencing and gene analysis, revealing the importance of specific genes (VdDf) in the defoliating strains of V. dahliae.
  • Notably, compounds like N-lauroylethanolamine (NAE) are linked to defoliation, suggesting that VdDfs influence the production of secondary metabolites responsible for the defoliation phenotype by affecting hormone sensitivity and plant responses.

Article Synopsis
  • * This study identified 30 CRK genes in cotton's genome, with significant clusters found on chromosomes A06 and D06, indicating that gene expansion may have occurred through tandem duplication.
  • * Examining gene expression showed that nine specific CRK genes were activated in response to VW infection, and silencing these genes reduced resistance to the disease, highlighting their crucial role in cotton's defense mechanisms.

Verticillium wilt caused by results in severe losses in cotton, and is economically the most destructive disease of this crop. Improving genetic resistance is the cleanest and least expensive option to manage Verticillium wilt. Previously, we identified the island cotton NBS-LRR-encoding gene that confers resistance to the highly virulent isolate Vd991.

Verticillium dahliae isolates are most virulent on the host from which they were originally isolated. Mechanisms underlying these dominant host adaptations are currently unknown. We sequenced the genome of V.

Cutinases have been implicated as important enzymes during the process of fungal infection of aerial plant organs. The function of cutinases in the disease cycle of fungal pathogens that invade plants through the roots has been less studied. Here, functional analysis of 13 cutinase (carbohydrate esterase family 5 domain-containing) genes (VdCUTs) in the highly virulent vascular wilt pathogen Verticillium dahliae Vd991 was performed.

Wilt caused by Verticillium dahliae significantly reduces cotton yields, as host resistance in commercially cultivated Gossypium species is lacking. Understanding the molecular basis of disease resistance in non-commercial Gossypium species could galvanize the development of Verticillium wilt resistance in cultivated species. Nucleotide-binding site leucine-rich repeat (NBS-LRR) proteins play a central role in plant defence against pathogens.

Fungal transcription factors (TFs) implicated in the regulation of virulence gene expression have been identified in a number of plant pathogens. In Verticillium dahliae, despite its agricultural importance, few regulators of transcription have been characterized. In this study, a T-DNA insertion mutant with significantly reduced virulence towards cotton was identified.

Glycoside hydrolase 12 (GH12) proteins act as virulence factors and pathogen-associated molecular patterns (PAMPs) in oomycetes. However, the pathogenic mechanisms of fungal GH12 proteins have not been characterized. In this study, we demonstrated that two of the six GH12 proteins produced by the fungus Verticillium dahliae Vd991, VdEG1 and VdEG3 acted as PAMPs to trigger cell death and PAMP-triggered immunity (PTI) independent of their enzymatic activity in Nicotiana benthamiana.

Degradation characteristics of typical organic compounds in landfill leachate were investigated by electrochemical oxidation and anaerobic process combined treatment system in this paper. In electrochemical oxidation system, degradation rate of polyphenolic, polyamide, benzothiazole, benzoquinone, quinoline and naphthalene compounds was higher than that of Exo-2-hydroxycineole and isoquinoline compounds, but that of the former was lower in anaerobic process. After electrochemical oxidation process, content of Volatile Fatty Acids (VFAs) markedly increased from 0.
