Differential expression of the Hsf family in cassava under biotic and abiotic stresses
Bibliographic record
Abstract
Heat shock transcription factors (Hsfs) are important regulators of biotic and abiotic stress responses in plants. Currently, the Hsf gene family is not well understood in cassava, an important tropical crop. In the present study, 32 MeHsf genes were identified from the cassava genome database, which were divided into three types based on functional domain and motif distribution analyses. Analysis of the differential expression of the genes belonging to the Hsf family in cassava was carried out based on published cassava transcriptome data from tissues/organs (leaf blade, leaf midvein, lateral buds, organized embryogenic structures, friable embryogenic callus, fibrous roots, storage roots, stem, petiole, shoot apical meristem, and root apical meristem) under abiotic stress (cold, drought) or biotic stress (mealybugs. cassava brown streak disease, cassava bacterial blight). The results show the expression diversity of cassava Hsfs genes in various tissues/organs. The transcript levels of MeHsfB3a, MeHsfA6a, MeHsfA2a, and MeHsfA9b were upregulated by abiotic and biotic stresses, such as cold, drought, cassava bacterial blight, cassava brown streak disease, and mealybugs, indicating their potential roles in mediating the response of cassava plants to environment stresses. Further interaction network and co-expression analyses suggests that Hsf genes may interact with Hsp70 family members to resist environmental stresses in cassava. These results provide valuable information for future studies of the functional characterization of the MeHsf gene family.

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.
