Culture collections as a source of historic strains for genomic studies in plant pathology
Bibliographic record
Abstract
Abstract The first microbial culture collection was established in 1890, and subsequently, over the course of the twentieth century, the number of culture collections grew substantially. One such collection was the CABI-IMI Genetic Resources Collection, informally initiated at the origins of the Commonwealth Mycological Institute in 1920 and established as a UK National Collection in 1947. Its holdings reflect the activities of CABI in agriculture and the environment. Like many collections, it was originally established as a taxonomic reference resource. Over the years, deposits have included strains isolated from disease outbreaks in major crops from all parts of the world. Recent developments in genome sequencing technology and bioinformatic analysis have opened up the potential to characterise historic strains to shed more insights on their biology and evolution. In this paper we describe how the resources held within the CABI-IMI culture collection have helped track the emergence and divergence of Fusarium xylarioides , the coffee wilt pathogen, with a specific focus on the evolution of pathogenicity. Such studies illustrate the value held within the world’s culture collections—their importance in underpinning science and developing our understanding and evolution of plant diseases as well as how the impact of disease can be mitigated in response to climate change, in order to increase yields and feed the world’s burgeoning population.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
