Novel spatial expression of soybean WUSCHEL in the incipient floral primordia.
Article in Planta, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The homeobox transcription factor WUSCHEL (WUS) is known to play a critical role in the maintenance of the stem cell population in shoot and floral meristems of Arabidopsis thaliana. The corresponding gene is yet to be characterized in soybean, a vital legume crop. In this study, we isolated the soybean ortholog of WUS (GmWUS) and explored its possible conserved function by in situ hybridization analysis and ectopic expression in Arabidopsis. GmWUS is expressed in the centre of soybean vegetative shoot apical meristem and floral meristem. Intriguingly, GmWUS is also found to be expressed in the incipient floral primordia before the formation of distinct floral meristem. This novel spatial expression pattern implicates GmWUS playing a role in the floral initiation process; it also raises the question of the molecular mechanism underlying the activation of GmWUS in these cells that have adopted the floral fate. Meanwhile, ectopic expression of GmWUS in Arabidopsis results in adventitious shoot and floral meristems' formation, and the disruption in floral organ patterning. These phenotypic alterations are largely consistent with the ectopic expression of Arabidopsis WUS, indicating similar function of GmWUS with its Arabidopsis counterpart. Nevertheless, our in situ hybridization analysis has revealed its spatial expression in the incipient floral primordia indicating an additional role of GmWUS in the floral initiation process.
