Microevolution of the VQ gene family in six species of <i>Fragaria</i>
Bibliographic record
Abstract
VQ motif-containing proteins play crucial roles in plant growth, development, and stress responses. However, no information of VQ motif-containing proteins has been studied at the microevolutionary level in species of Fragaria. In this study, a total of 19, 21, 23, 23, 23, and 25 genes containing the VQ motif were identified from the genomes of F. nipponica, F. iinumae, F. orientalis, F. vesca, F. nubicola, and F. x ananassa, respectively. We classified the VQ genes into 15 clades with grapevine VQ genes, which indicated that at least 15 ancient VQ genes existed before the divergence of the six studied species of Fragaria. Phylogenetic analysis indicated that 28 gene duplication events have occurred in the evolutionary process of the six species of Fragaria. Structural analysis showed that most of the VQ genes have no introns and that VQ proteins in each clade have a similar motif composition. The majority of gene pairs had K a /K s ratios less than 1, which illustrated that most of the VQ genes underwent purifying selection in the six species of Fragaria. Four types of cis-elements in promoters of VQ genes were detected, which is an important basis for further studies about plant stress responses. Furthermore, the expression analysis of FvVQ genes indicated that these genes are expressed differentially in the examined organs and tissues. The identification of VQ genes and the analysis of VQ gene duplication and polyploidization events in the six species of Fragaria provide important information on the evolutionary fate of VQ genes during the divergence of the six species of Fragaria.

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.
