Sequence characterization and expression pattern of BcMF21, a novel gene related to pollen development in Brassica campestris ssp. chinensis.
Article in Molecular biology reports, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
In this report a full length cDNA, Brassica campestris Male Fertile 21 (BcMF21) was successfully isolated from one of the cDNA-amplified fragment length polymorphism (cDNA-AFLP) transcript-derived fragments (TDFs), BBP10, that was found down-regulated in the flower buds of sterile plants in Brassica campestris L. ssp. chinensis Makino genic male sterile (GMS) AB line system (Bcajh 97-01A/B). BcMF21 protein structure analysis showed a signal peptide at the N-terminus; two protein kinase C phosphorylation sites, five N-myristoylation sites and one casein kinase II phosphorylation site. The promoter region of BcMF21, a 779 bp upstream of ATG was isolated by thermal asymmetric interlaced-PCR (TAIL-PCR). Bioinformatics analysis revealed that the promoter of BcMF21 contained several classical cis-acting elements and three pollen specific elements. Transient expression analysis showed that the promoter could drive green fluorescence protein (GFP) expression. Quantitative reverse transcript-PCR analysis revealed that BcMF21 was specifically expressed in flower buds. The transcript level of BcMF21 was much lower in the sterile flower buds than in the fertile flower buds in 'Bcajh 97-01A/B' system. In situ hybridization further showed that BcMF21 was only expressed in the tetrads and the microspores at the tetrad stage and the uninucleate stage. In addition, phylogenetic analysis demonstrated that the BcMF21 was relative conserved within family Crucifereae and might be originated from the ancestor diploid B. campestris within genus Brassica according to the Triangle of U theory.
