Phytoplasma Genotypes in Grapevine Disease Vectors and Host Plants

ENVIDAT provides data from a survey investigating the roles of the common alder tree (Alnus glutinosa) and the insect Orientus ishidae in the epidemiology of Flavescence dorée, a grapevine disease. The dataset supports a 2021 publication and contains molecular analysis results from samples collected around a vineyard in the Swiss Southern Alps. It was used to identify and compare phytoplasma genotypes across insects, grapevines, and alder trees.

Use Cases

• Compare map genotypes and sequences of the Flavescence dorée phytoplasma (16SrV-p) across insect vectors, grapevines, and common alder hosts.
• Analyze co-occurrence of Flavescence dorée and Bois Noir phytoplasma (16SrXII-p) infections in samples from the surveyed vineyard ecosystem.
• Study the epidemiological link between the secondary vector Orientus ishidae and the host plant Alnus glutinosa using molecular identification data.
• Correlate insect capture data from sweeping nets and yellow sticky traps with phytoplasma infection status from molecular analyses.

Strengths

• Data is linked to a specific peer-reviewed scientific publication, ensuring research relevance.
• Includes molecular characterization (genotyping and sequencing) for comparative analysis across species.
• Samples were collected using standardized techniques for both insect capture and plant sampling.

Limitations

• The sample size and number of rows are unknown, limiting statistical assessment.
• Geographic coverage is limited to the surroundings of a single vineyard in the Swiss Southern Alps.
• Data is from a 2021 publication and may not reflect current disease dynamics.
