Suppressive subtractive hybridization and differential screening identified genes differentially expressed in yeast and mycelial forms of<i>Ophiostoma piceae</i>
Bibliographic record
Abstract
Ophiostoma piceae is a sap-staining fungus that colonizes and discolours wood. It has been established that the mycelium form but not the yeast form becomes pigmented in vitro. Suppressive subtractive hybridization PCR was used to isolate transcripts specifically upregulated in either the yeast or mycelial forms of O. piceae. Subtracted cDNAs were cloned and transformed into Escherichia coli. The yeast and mycelium specific clones were then screened by differential screening to reduce the possibility of isolating false positive clones and the differential expression of the two sets of cDNAs was confirmed by reverse Northern hybridization. Numerous genes appear to be specifically expressed in either the yeast or mycelial forms. Sequence analysis identified several cDNAs similar to known genes. However, a few cDNAs showed no similarity to sequences in the public databases.
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.
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.
