Genome-wide identification, structural analysis and expression profiles of GRAS gene family in orchardgrass.
Article in Molecular biology reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 GRAS gene family is a family of transcription factors that regulates plant growth and development. Despite being well-studied in many plant species, little is known about this gene family in orchardgrass (Dactylis glomerata L.), one of the top four economically important perennial forage grasses cultivated worldwide. We identified 46 GRAS genes in orchardgrass and analyzed their characteristics by phylogenetic, gene structural, motifs and expression patterns analysis. The phylogenetic analysis of eight species revealed that DgGRAS family had the evolutional conservation and closer homology relationship with the GRAS family of rice, barley and Brachypodium distachyon. Moreover, 46 DgGRAS proteins were divided into eight subfamilies based on the tree topology and rice or Arabidopsis classification, and LISCL subfamily was the largest one. Besides, we found that the motif 15 may be unique to the orchardgrass LISCL subfamily, and the motif 6 and motif 17 had indispensable functions in the orchardgrass LISCL subfamily. We further analyzed the expression profiles of DgGRAS genes at mature and seeding stage. And we found that DgGRAS17 played an important role in the growth and development no matter what stage it was at. DgGRAS5, DgGRAS28, DgGRAS31, DgGRAS42 and DgGRAS44 got involved in processes of the growth and development at seeding stage instead of mature stage. These results indicated that the major expression patterns and detailed functions of the DgGRAS genes varied with developmental stages. Taken together, this is the first systematic analysis of the GRAS gene family in the orchardgrass genome and the results provide insights into the potential functions of GRAS genes.
