Role of phasiRNAs from two distinct phasing frames of GhMYB2 loci in cis- gene regulation in the cotton genome.
Article in BMC plant biology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundPhased small interfering RNA (phasiRNA) is primarily derived from the 22-nt miRNA targeting loci. GhMYB2, a gene with potential roles in cotton fiber cell fate determination, is a target gene of miR828 and miR858 in the generation of phasiRNAs.
resultsIn the presented work, through the evaluation of phasing scores and phasiRNA distribution pattern, we found that phasiRNAs from GhMYB2 were derived from the 3' cleavage fragments of 22-nt miR828 and 21-nt miR858 respectively. These two miRNA targeting sites initiated two phasing frames on transcripts of one locus. By means of RNA ligase-mediated rapid amplification of cDNA ends (RLM-RACE), we further demonstrated that phasiRNAs derived from the two phasing frames played a role in cis-regulation of GhMYB2. The phasiRNAs derived from GhMYB2 were expressed in the somatic tissues, especially in anther and hypocotyl. We further employed our previous small RNA sequencing data as well as the degradome data of cotton fiber bearing ovules, anthers, hypocotyls and embryogenic calli tissues published in public databases, to validate the expression, phasing pattern and functions of phasiRNAs.
conclusionsThe presenting research provide insights of the molecular mechanism of phasiRNAs in regulation of GhMYB2 loci.
