The LLA23 protein translocates into nuclei shortly before desiccation in developing pollen grains and regulates gene expression in Arabidopsis.
Article in Protoplasma, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
We have isolated the LLA23 gene in the pollen of Lilium longiflorum. The LLA23 gene encodes an ASR (named after abscisic acid, stress and ripening) protein that has a nuclear localization sequence at the C terminus. The gene is interrupted by one single intron and possesses a long 5'-untranslated region. Southern blots of lily genomic DNA indicated that LLA23 is a member of a small gene family. We examined the link between LLA23 location and the desiccation that naturally occurs in developing anthers using immunogold labeling. When pollen reached maturity, a significant increase in LLA23 labeling was observed in the nuclei of both vegetative and generative cells from 10- to 12-cm buds and thereafter. This clearly demonstrates that a marked increase in LLA23 translocation from the cytoplasm to both nuclei of pollen grains occurs in 12-cm buds, a stage shortly before the commencement of desiccation during anther development. In addition, microarray analysis showed that 410 (206 up-regulated and 204 down-regulated) genes have altered expression in LLA23-overexpressing plants. Quantitative PCR analysis confirmed the changes in mRNA levels observed in our microarray analysis. This genome-wide overview of gene expression supports the theory that LLA23 acts as a regulator.
