Integrative Pathogenicity Assay and Operational Taxonomy-Based Detection of New Forma Specialis of Causing Datepalm Wilt.

Pathogenicity-associated genes are highly host-specific and contribute to host-specific virulence. We tailored the traditional Koch's postulates with integrative omics by hypothesizing that the effector genes associated with host-pathogenicity are determinant markers for virulence, and developed Integrative Pathogenicity (IP) postulates for authenticated pathogenicity testing in plants. To set the criteria, we experimented on datepalm () for the vascular wilt pathogen and confirmed the pathogen based on secreted in xylem genes (effectors genes) using genomic and transcriptomic approaches, and found it a reliable solution when pathogenicity is in question.

First report of causing wood necrosis in European hazelnut in Chile.

In Chile, the planted area of European hazelnut ( L.) reaches around 30,000 hectares, mainly concentrated in the central and southern area of the country where climate and soil provide a natural environment well suited to growing this species. Only a few diseases affect this nut tree in Chile.

spp. Genes Involved in the Biocontrol Activity Against .

is a pathogen that causes considerable harm to plants worldwide. In the absence of hosts, survives in the soil by forming sclerotia, and management methods, such as cultivar breeding, crop rotations, and fungicide sprays, are insufficient and/or inefficient in controlling . One of the most challenging problems facing agriculture in the twenty-first century besides with the impact of global warming.

Antagonistic Activity of Chilean Strains of Against Fungi Causing Crown and Root Rot of Wheat ( L.).

Seed treatments with antagonistic bacteria could reduce the severity of crown and root rot diseases in wheat crops. The objective of this study was to evaluate the potential antagonistic activity of a bacterial consortium of three Chilean strains of against the wheat crown and root rot pathogens var. , , and .

Population Dynamics Between Fusarium pseudograminearum and Bipolaris sorokiniana in Wheat Stems Using Real-Time qPCR.

Fusarium pseudograminearum and Bipolaris sorokiniana are causal agents of Fusarium crown rot and common root rot, respectively, of wheat and cause significant losses worldwide. Understanding the population dynamics between these two pathogens at late stages of wheat development is needed. The effect of F.

Distribution and Prevalence of Fusarium Crown Rot and Common Root Rot Pathogens of Wheat in Montana.

Distribution of Fusarium crown rot (FCR) and common root rot (CRR) pathogens associated with wheat (Triticum aestivum) in 91 fields in Montana were determined during the 2008 and 2009 crop seasons using real-time quantitative polymerase chain reaction (qPCR) and conventional isolation methods. Correlations (P < 0.001) were found between detection methods for both diseases.
