Genomic and molecular analysis of conserved and unique features of soybean PIF4.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Phytochrome-interacting factor 4 (PIF4) participates in light signaling by interacting with photoreceptors, phytochromes, and cryptochromes. Although well characterized in Arabidopsis, PIF4's role in crop plants is unknown. Here we performed the first integrated genomics, transcriptomics, and molecular characterization of PIF4 in soybean (Glycine max) plants. Fifteen identified Glycine max PIFs (GmPIFs) grouped into PIF3, PIF4, and PIF8 subfamilies based on their phylogenetic relationships. The GmPIF4 subfamily formed two distinct clades (GmPIF4 I and GmPIF4 II) with different amino acid sequences in the conserved bHLH region. Quantitative transcriptional analysis of soybean plants exposed to different photoperiods and temperatures indicated that all PIF4 I clade GmPIF4s conserved PIF4-like expression. Three out of four GmPIF4 transcripts of the GmPIF4 I clade increased at 35 °C compared to 25 °C under short day conditions. RNA sequencing of soybeans undergoing floral transition showed differential regulation of GmPIF4b, and ectopic GmPIF4b expression in wild type Arabidopsis resulted in an early flowering phenotype. Complementation of GmPIF4b in Arabidopsis pif4-101 mutants partially rescued the mutant phenotype. PIF4 protein levels peaked before dawn, and a GmPIF4b protein variant was observed in soybean plants treated at high temperatures.
