Overexpression of Zostera japonica heat shock protein gene ZjHsp70 enhances the thermotolerance of transgenic Arabidopsis.
Article in Molecular biology reports, 2022. 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
backgroundHeat shock protein 70s (Hsp70s) are major members of the heat shock protein family and play a variety of roles to protect plants against stress. Plant Hsp70s are a conserved and widely expressed family of heat shock proteins. They have two main functional regions: N-terminal nucleic acid binding region and C-terminal substrate binding region. METHODS AND
resultsIn this study, we cloned the Hsp70 gene of Zostera japonica (ZjHsp70) based on the sequence obtained by transcriptome sequencing. The transcriptional levels of ZjHsp70 increased significantly at 1 h after heat treatment. ZjHsp70 was located in the cytoplasm and nucleus. The overexpression of ZjHsp70 in Arabidopsis resulted in increased heat tolerance, lower contents of malondialdehyde and higher antioxidant enzyme activity than in the wild type. ZjHsp70 may achieve this goal by maintaining highly active antioxidant enzymes.
conclusionsWe show that ZjHsp70 can improve plant heat tolerance by maintaining high antioxidant enzyme activity under high temperature stress. This study provided a basis to study the role of ZjHsp70 in thermotolerance in more detail.
