Identification and Genetic Characterization of a New d10 Mutated <i>Indica</i> Rice Germplasm
Bibliographic record
Abstract
Plant architecture is a determining factor for yield of cereal crop rice. Multi-tiller and dwarf mutants are useful germplasms for the study of rice plant architecture. In this research, we investigated a new multi-tiller and dwarf mutant, Jiahecong’ai (JHCA), and compared its genetic characteristics with 6 other rice varieties or lines. Two F 2 populations were developed by crossing JHCA with Gaoliangdao 1 (GLD1) and Guangchang 13 (GC13), which were used for further studies. Our results showed that the extreme dwarf and multitiller phenotype of JHCA was controlled by a recessive locus named xmd(t) . The xmd(t) locus was fine mapped to an interval between XMd-SSR4 and XMd-SSR25 marker on chromosome 2, which spans 190 kb in length including 28 annotated genes. Allelic sequence analysis revealed that the xmd(t) of JHCA has a 40-bp deletion in D10 gene, which encodes a carotenoid cleavage dioxygenase 8 (OsCCD8) involved in strigolactone (SL) biosynthesis pathway. Further genetic analysis suggested that JHCA should be a good rice germplasm for studying plant architecture in rice as well as metabolism interactions between gibberellin and strigolactone based on the reinforcement of dwarfing effect by d10 and sd1 .

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.
