Fine mapping of BH1, a gene controlling lemma and palea development in rice.
Article in Plant cell reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
key messageA new rice floral organ mutant bh1 , had a negative effect on grain yield. BH1 was fine mapped to 87.5 kb on chr2. A 55 kb chromosome segment was deleted in bh1. The cereal spikelet is enclosed by the lemma and palea. The lemma and palea of the floral mutant designated bh1, a selection from a T-DNA library generated from the rice cultivar Asominori, takes on an abnormal curve-shaped appearance only late in floral development, finally forming a beak-shaped hull. The mutation had a negative effect on thousand grain weight, seed set rate and germination rate. Genetic analysis indicated that the mutant phenotype was determined by a single recessive gene. Through map-based approach, BH1 gene was finally located to a ~87.5-kbp region on the long arm of chromosome 2. An analysis of the gene content of this region indicated that the mutation involves the loss of a 55-kbp stretch, harboring four open reading frames. Transcription profiling based on qRT-PCR revealed that the genes OsMADS1, OsMADS14, OsMADS15, OsMADS18, REP1, CFO1, and DL, all of which are also involved in lemma and palea development and identity specification, were down-regulated in the bh1 mutant. BH1 is therefore an important floral organ development gene.
