<i>Rhizoctonia</i> fungi enhance the growth of the endangered orchid <i>Cymbidium goeringii</i>
Bibliographic record
Abstract
Orchids are among the most prized ornamental plants in many societies throughout the world. As a result, consumer demands have created a significant pressure on wild populations of many species, including Cymbidium goeringii Rchb. f., a rare terrestrial orchid endemic in China, Korea, and Japan. To help conserve natural populations of C. goeringii, we recently started investigating methods to cultivate these orchids. Here we fulfilled Koch’s postulates and demonstrated that fungal strains isolated from the roots of natural Cymbidium plants increased fresh mass, plant height, number of leaves, and root length of C. goeringii, and that the two fungal strains originally isolated from C. goeringii showed overall greater effects on growth than two other strains from other Cymbidium species. Internal transcribed spacer sequence analyses revealed that the four fungal strains likely represented at least two new taxonomic groups, both belonging to the family Ceratobasidiaceae of the Rhizoctonia fungi. Our study demonstrated that these fungal strains could potentially help the commercial cultivation of the increasingly rare and endangered orchid C. goeringii.

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.
