Isolation and characterization of hexokinase genes PsHXK1 and PsHXK2 from tree peony (Paeonia suffruticosa Andrews).
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 8 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
Hexokinase (HXK) plays important roles in hexose phosphorylation and sugar signaling. HXK regulates the glucose-induced accumulation of anthocyanin in many species. Little is known about the biological function of the HXK gene family in Paeonia suffruticosa. cDNA sequences of two hexokinase genes PsHXK1 and PsHXK2 were isolated using RACE-PCR and RT-PCR from P. suffruticosa. PsHXK1 encodes 498 amino acids with a 1497-bp open reading frame (ORF), and PsHXK2 contains 493 amino acids with a 1482-bp ORF. Sequence and phylogenetic analyses suggest that PsHXK1 and PsHXK2 belong to type-B HXK and may function as glucose sensors. PsHXK1 and PsHXK2 mRNA were detected in all tested tissues. PsHXK1 is highly expressed in petals and stamens, while PsHXK2 is highly expressed in stamens. At the former stages of flower opening, PsHXK1 and PsHXK2 show higher expression levels in on-tree flowers compared with cut flowers. Overexpressing PsHXK1 and PsHXK2 in Arabidopsis enhances glucose sensitivity, inhibits plant growth in response to glucose, and induces anthocyanin accumulation in response to the high level of glucose. Overall, our results primarily reveal the biological function of PsHXK1 and PsHXK2, especially their involvement in glucose-induced anthocyanin accumulation.
