Genome-wide characterization and expression analyses of the auxin/indole-3-acetic acid (Aux/IAA) gene family in barley (Hordeum vulgare L.).
Article in Scientific reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Aux/IAA genes are early auxin-responsive genes and essential for auxin signaling transduction. There is little information about Aux/IAAs in the agriculturally important cereal, barley. Using in silico method, we identified and subsequently characterized 36 Aux/IAAs from the barley genome. Based on their genomic sequences and the phylogenic relationship with Arabidopsis and rice Aux/IAA, the 36 HvIAAs were categorized into two major groups and 14 subgroups. The indication of the presence or absence of these domains for the biological functions and acting mechanisms was discussed. The cis-element distributions in HvIAA promoters suggests that the HvIAAs expressions may not only regulated by auxin (the presence of AuxREs and TGA-element) but also by other hormones and developmental and environmental cues. We then studied the HvIAAs expression in response to NAA (1-Naphthaleneacetic acid) using quantitative real-time PCR (qRT-PCR). Like the promoter analysis, only 14 HvIAAs were upregulated by NAA over two-fold at 4 h. HvIAAs were clustered into three groups based on the spatiotemporal expression data. We confirmed by qRT-PCR that most HvIAAs, especially HvIAA3, HvIAA7, HvIAA8, HvIAA18, HvIAA24 and HvIAA34, are expressed in the developing barley spike compared within seedling, suggesting their roles in regulating spike development. Taken together, our data provide a foundation for further revealing the biological function of these HvIAAs.
