[Cloning of ACC oxidase gene and inhibition of endogenous gene expression with RNAi in cauliflower].
Bibliographic record
Abstract
A fragment of 1202 bp of the candidate ACO gene was amplified from the cauliflower (brassica oleracea Var. botrytis) genome using the degenerated primers which were designed according to the consensus sequence of ACO amino acids among various plant species. The result of BLAST showed the sequence presented a very high match with the ACO genes from other plants; the homologue was from 83% to 99%. Three exons and two introns were identified in this sequence. The spliced length of mRNA was 756 nt and encoded 252 amino acids. The putative new gene was denominated BoACO, and submitted to GenBank (AY676466). Using the sequence, we constructed an RNA interference (RNAi) transformation vector through the way of BP cloning. The transformation into cauliflower was performed. Five regenerated plants with kanamycin resistance were obtained. And the transgene integrated into cauliflower genome was proved with PCR and Southern blotting. The expression of this ACO gene is down-regulated based on the Northern blotting in the transgenic plants. The activity of ACO enzyme was depressed significantly.
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.
