Abstract
Although many different crop species have been used to produce a wide range of vaccines, antibodies, biopharmaceuticals and industrial enzymes, tobacco has the most established history for the production of recombinant proteins. To further improve the heterologous protein yield of tobacco platforms, transient and stable expression of four recombinant proteins (i.e. human erythropoietin and interleukin-10, an antibody against Pseudomonas aeruginosa, and a hyperthermostable α-amylase) was evaluated in numerous species and cultivars of Nicotiana. Whereas the transient level of recombinant protein accumulation varied significantly amongst the different Nicotiana plant hosts, the variety of Nicotiana had little practical impact on the recombinant protein concentration in stable transgenic plants. In addition, this study examined the growth rate, amount of leaf biomass, total soluble protein levels and the alkaloid content of the various Nicotiana varieties to establish the best plant platform for commercial production of recombinant proteins. Of the 52 Nicotiana varieties evaluated, Nicotiana tabacum (cv. I 64) produced the highest transient concentrations of recombinant proteins, in addition to producing a large amount of biomass and a relatively low quantity of alkaloids, probably making it the most effective plant host for recombinant protein production.

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 it
