The floral inoculating protocol: a simplified Arabidopsis thaliana transformation method modified from floral dipping
Bibliographic record
Abstract
The floral dip protocol mediated by Agrobacterium tumefaciens is the most widely used transformation method for Arabidopsis thaliana. The “floral dip” process in which A. thaliana flower buds are dipped in an Agrobacterium cell suspension requires large volumes of bacterial cultures grown in liquid media, large shakers and centrifuges, and experimental space for them. These factors limit the number of transformations that can occur at once. We established that A. thaliana can be transformed by inoculating 5 μl of Agrobacterium cell suspension in flower buds, thus avoiding the use of large volumes of Agrobacterium culture. Using this modified protocol, we obtained 15–50 transgenic plants per transformation from each pot containing 3 A. thaliana plants. The protocol is satisfactory to be used for subsequent analyses. This simplified method, without floral dipping, which requires large volumes of Agrobacterim culture, offers as efficient a transformation as previously reported protocols. This method reduces the required workload, cost, time, and space. Furthermore, an important aspect of this modified protocol is that it allows many independent transformations to be performed at once.

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.
