Penicillium and Talaromyces Communities of Sugarcane Soils (Saccharum officinarum L.): Ecological and Phylogenetic Aspects
Bibliographic record
Abstract
Penicillium and Talaromyces are fungal genera with high ecological and biotechnological importance. However, studies on exploration and ecology of these fungi in soils are scarce. The objectives of this study were to evaluate the species diversity of these genera in soils of sugarcane and fallow. Identification of the isolates was performed by morphological examination and partial sequencing of Beta-tubulin. For ecological analyses, indexes were applied and principal component analysis (PCA) was performed. A total of 1,344 isolates were obtained: 1,108 of Penicillium (13 species) and 236 of Talaromyces (three species). Seven isolates did not cluster with any known species. The diversity and equitability indexes were similarly high for the two areas analyzed. Penicillium wotroi and Talaromyces murroi were more abundant. The PCA was significant and showed 2 groups: fallow and cultivated. Soils of sugarcane cultivation present distinct communities of Penicillium and Talaromyces species that are rare and/or not yet described by science.
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.
