Genome-wide analysis and molecular dissection of the SPL gene family in Fraxinus mandshurica.
Article in BMC plant biology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
backgroundSQUAMOSA promoter binding protein-like (SPL) is a unique family of transcription factors in plants, which is engaged in regulating plant growth and development, physiological and biochemical processes. Fraxinus mandshurica is an excellent timber species with a wide range of uses in northeastern China and enjoys a high reputation in the international market. SPL family analysis has been reported in some plants while SPL family analysis of Fraxinus mandshurica has not been reported.
resultsWe used phylogeny, conserved motifs, gene structure, secondary structure prediction, miR156 binding sites, promoter cis elements and GO annotation to systematically analyze the FmSPLs family. This was followed by expression analysis by subcellular localization, expression patterns at various tissue sites, abiotic stress and hormone induction. Because FmSPL2 is highly expressed in flowers it was selected to describe the SPL gene family of Fraxinus mandshurica by ectopic expression. Among them, 10 FmSPL genes that were highly expressed at different loci were selected for expression analysis under abiotic stress (NaCl and Cold) and hormone induction (IAA and ABA). These 10 FmSPL genes showed corresponding trends in response to both abiotic stress and hormone induction. We showed that overexpression of FmSPL2 in transgenic Nicotiana tabacum L. resulted in taller plants, shorter root length, increased root number, rounded leaves, and earlier flowering time.
conclusionsWe identified 36 SPL genes, which were classified into seven subfamilies based on sequence analysis. FmSPL2 was selected for subsequent heterologous expression by analysis of expression patterns in various tissues and under abiotic stress and hormone induction, and significant phenotypic changes were observed in the transgenic Nicotiana tabacum L. These results provide insight into the evolutionary origin and biological significance of plant SPL. The aim of this study was to lay the foundation for the genetic improvement of Fraxinus mandshurica and the subsequent functional analysis of FmSPL2.
