Cell dedifferentiation and organogenesis in vitro require more snRNA than does seedling development in Arabidopsis thaliana.
Article in Journal of plant research, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Small nuclear RNA (snRNA) is a class of non-coding RNAs that processes pre-mRNA and rRNA. Transcription of abundant snRNA species is regulated by the snRNA activating protein complex (SNAPc), which is conserved among multicellular organisms including plants. SRD2, a putative subunit of SNAPc in Arabidopsis thaliana, is essential for development, and the point mutation srd2-1 causes severe defects in hypocotyl dedifferentiation and de novo meristem formation. Based on phenotypic analysis of srd2-1 mutant plants, we previously proposed that snRNA content is a limiting factor in dedifferentiation in plant cells. Here, we performed functional complementation analysis of srd2-1 using transgenic srd2-1 Arabidopsis plants harboring SRD2 homologs from Populus trichocarpa (poplar), Nicotiana tabacum (tobacco), Oryza sativa (rice), the moss Physcomitrella patens, and Homo sapiens (human) under the control of the Arabidopsis SRD2 promoter. Only rice SRD2 suppressed the faulty tissue culture responses of srd2-1, and restore the snRNA levels; however, interestingly, all SRD2 homologs except poplar SRD2 rescued the srd2-1 defects in seedling development. These findings demonstrated that cell dedifferentiation and organogenesis induced during tissue culture require higher snRNA levels than does seedling development.
