1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

One putative quantitative trait locus (QTL) for seeds per silique (SS), cqSS.A8, was identified using a double haploid (DH) population in Brassica napus, and near-isogenic lines (NILs; BC(3)F(1)) for cqSS.A8 were developed. However, the flanking markers from cqSS.A8 showed no significant difference using single-marker analysis, even though the frequency distribution of SS in the BC(3)F(1) was bimodal, suggesting that one novel locus existed. In this study, we characterized the effects of this locus in the NILs and used a published linkage map to determine its location. A three-step approach was designed for mapping the locus in the NILs (BC(3)F(2)): (1) determining the individual BC(3)F(2) genotype at the locus using a progeny test; (2) identifying amplified fragment length polymorphism (AFLP) markers linked to the locus using a combination of AFLP and bulked segregant analysis; and (3) determining the location and effects of this locus. QTL analysis in the BC(3)F(2) revealed that this locus explained 85.8 and 55.7 % of phenotypic variance for SS and SL, respectively. Its additive and dominant effects on SS were 6.1 and 5.7, respectively. The locus was validated using a DH population by composite interval mapping and located to linkage group C9 (designated as qSS.C9). Mapping qSS.C9 was undertaken using 230 extremely low-SS plants of a BC(4)F(1) population containing 807 plants. We found that qSS.C9 delimited a 1.005-Mb interval including 218 predicted genes in the reference Brassica rapa (Chiifu-401). These results will greatly facilitate map-based cloning of qSS.C9 and seed yield improvement in rapeseed.
