Development of transient expression assay for <i>Cannabis sativa</i> which revealed differential <i>Agrobacterium</i> susceptibility among cannabis cultivars
Bibliographic record
Abstract
Abstract In plant biology, transient expression analysis plays a vital role to provide a fast method to study the gene of interest and subsequently leads the path to develop an improved crop variety with better agronomic traits. In this study, we have reported a rapid and efficient method for transient expression in Cannabis sativa seedlings using Agrobacterium tumefaciens -mediated transformation. A. tumefaciens strain EHA105 carrying the pCAMBIA1301 construct with uid A gene was used to transform cannabis seedlings and the GUS assay was used to detect the uid A expression. A 1% hydrogen peroxide (H 2 O 2 ) solution was used for both seed sterilization and rapid germination steps. Transient transformation revealed that both cotyledons and young true leaves are amenable to transformation. Comparison to Nicotiana tabacum (tobacco) showed that cannabis seedlings were less susceptible to transformation with Agrobacterium tumefaciens . The susceptibility to Agrobacterium infection also varied with the different cannabis cultivars. The method established in this study has potential to be an important tool for gene-function studies and genetic improvement in cannabis.

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.
