A Cotton Cyclin-Dependent Kinase E Confers Resistance to Verticillium dahliae Mediated by Jasmonate-Responsive Pathway
Bibliographic record
Abstract
Many subunits of the Mediator transcriptional co-activator complex are multifunctional proteins that regulate plant immunity in Arabidopsis. Cotton cyclin-dependent kinase E (GhCDKE), which is a subunit of the cotton (Gossypium hirsutum) Mediator complex, has been annotated, but the biological functions of this gene associated with regulating disease resistance have not been characterized. Here, we cloned GhCDKE from cotton and confirmed that GhCDKE belonged to the E-type CDK family in the phylogenetic tree, and, as in other eukaryotes, we found that GhCDKE interacted with C-type cyclin (GhCycC) by yeast two-hybrid and luciferase complementation imaging assays. Expression of GhCDKE in cotton was induced by Verticillium dahliae infection and MeJA treatment, and silencing of GhCDKE expression in cotton led to enhanced susceptibility to V. dahliae, while overexpression of GhCDKE in Arabidopsis thaliana enhanced resistance to this pathogen. Transgenic expression assay demonstrated that the transcriptional activity of GhPDF1.2pro:LUC in GhCDKE-silenced cotton was dramatically inhibited. In addition, the expression of jasmonic acid (JA)-regulated pathogen-responsive genes was dramatically up-regulated in GhCDKE-overexpressed plants after inoculation with V. dahliae, and the roots of GhCDKE-overexpressed A. thaliana were more susceptible to MeJA treatment. These results indicated that GhCDKE regulates resistance against V. dahliae and that this resistance is mediated by JA response pathway.

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.
