Abstract

fetched live from OpenAlex

<title>Abstract</title> The reference strain of '<italic>Ca.</italic> Phytoplasma trifolii' is the causative agent of clover proliferation (CP) disease of alsike clover (<italic>Trifolium hybridum</italic>). The CP disease was first reported in Canada in the early 1960s when the aetiological agent was mistakenly presumed to be a yellows-type virus (Chiykowski, 1965). Subsequent investigations revealed that the disease was associated with infection by a mycoplasma-like organism (Chen and Hiruki, 1975&gt;; Hiruki and Chen, 1984), now termed phytoplasma, strain CP<sup>R</sup> (Hiruki and Wang, 2004). Later, phytoplasmas of the same lineage (subgroup 16SrVI-A) were found in the USA, Mexico, and many countries in Europe and Asia, causing diseases in diverse leguminous and vegetable crops, responsible for significant yield losses and quality reductions. Phytoplasmas of the same lineage also caused disease in elm trees in the USA. Phytoplasmas of closely-related lineages (various subgroups of group 16SrVI) also have wide distributions around the world.

Full frame distilled prediction

Teacher imitation

Not 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.
