Production of Transgenic Soybean Plants with Two Anti-Fungal Protein Genes Via Agrobacterium and Particle Bombardment
Bibliographic record
Abstract
Utilizing either Agrobacterium-mediated transformation or particle bombardment we obtained transgenic soybean [Glycine max (L.) Merr.] plants expressing the chitinase gene (chi) and the barley ribosome-inactivating protein gene (rip). Six regenerated plants were grown to maturity and set seed. The identification of transgenic soybean plants that co-integrated the two anti-fungal protein genes was determined by polymerase chain reaction (PCR) and Southern blot analysis. Protein detection from the soybean leaves demonstrated the expression of the chitinase (CHI) and the ribosome-inactivating protein (RIP) in the six R0 transformants. Soybean cotyledonary nodes were transformed using the bivalent plant expression vector pBRC containing chi and rip both driven by the CaMV 35S double promoter. Following vacuum (0.06 MPa) infiltration treatment of the tissue for 5 min, Agrobacterium was co-cultivated with the cotyledonary nodes for 3 d on MSB medium (MS salts and B5 vitamins) (pH 5.2), the transformation frequency reached a maximum of 1.33 %. The chi and rip genes were present in all the transgenic plants. Co-bombardment of immature cotyledons with plasmids pBchE (encoding chi) and pARIP (encoding rip) resulted in a maximum transformation frequency of 0.52 % with a 50 % co-integration rate. Our results demonstrate efficient co-transformation of multiple genes in soybean.

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.
