Identification of novel candidate of brown planthopper resistance gene <i>Bph44</i> in rice (<i>Oryza sativa</i> L.)
Bibliographic record
Abstract
The brown planthopper (BPH, Nilaparvata lugens Stål) is still considered a major threat to rice farmers. Exploring novel resistance genes that relate to the BPH population in the targeted rice-growing area might be a suitable solution. We identified and mapped the gene locus using 175 lines of F 2:3 populations derived from Balamawee × PD601. Genomic analysis was then used to identify the candidate gene governing the resistance toward BPH. We discovered a novel genetic locus for BPH resistance in the long arm of chromosome 4 linked to markers Q31 and RM17007 at 4.76 and 5.42 cM, respectively, with total phenotypic variation reaching 52.21% at LOD 29.68. The tolerance mechanism influences the nature of this resistance, as shown by the Functional Plant Loss Index. The resistance level, mechanism of resistance, and physical mapping reveal that the resistance genes in this study differ from the previous study, therefore, we propose this novel gene as Bph44.

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.
