Current status and future prospects of grapevine anthracnose caused by <i>Elsinoe ampelina</i>: An important disease in humid grape‐growing regions
Bibliographic record
Abstract
Anthracnose, caused by Elsinoe ampelina, is one of the most destructive diseases of grapevines worldwide, especially in humid areas. E. ampelina mainly infects young tissues starting from shoots to berries and affects vine vigour and berry yield. The occurrence and the role of the sexual stage in the disease cycle and the grapevine-E. ampelina interaction remain poorly understood. However, the recent genome sequence data of E. ampelina provides the basis for further studies to understand its evolution, pathogenicity mechanisms, and effector repertoire. New studies on E. ampelina have been conducted in recent years. In this pathogen profile, we present a comprehensive literature review of E. ampelina to summarize the findings on its aetiology, infection mechanisms, genome, pathogenicity, and host resistance. TAXONOMY: Elsinoe ampelina Shear; Kingdom Fungi; Phylum Ascomycota; Subphylum Pezizomycotina; Class Dothideomycetes; Subclass Dothideomycetidae; Order Myriangiales Starbäck; Family Elsinoaceae Höhnel; Genus Elsinoe Racib. HOST RANGE: E. ampelina only infects Vitis species and hybrids. DISTRIBUTION: The grapevine anthracnose is distributed worldwide but is most prevalent in Argentina, Australia, Brazil, Canada, China, India, Japan, Korea, New Zealand, South Africa, Thailand, USA, and Uruguay. DISEASE SYMPTOMS: E. ampelina causes slightly abundant depressed spots on young leaves, petioles, stems, tendrils, rachises, and berries. Under severe infection conditions, early defoliation, berry dropping, and delayed berry development and ripening may occur. GENOME: The genomes of two E. ampelina isolates, YL-1 and CECT 20119, are publicly released with 8,057 and 10,207 predicted genes, respectively.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
