Drought response of tuber genes in processing potatoes (Solanum tuberosum L.) in Japan.
Article in Molecular biology reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundLimited crop production due to lower rainfall has a major impact on the supply and demand of food for the human population. In potato (Solanum tuberosum L.), one of the major crops, there is also concern about a lack of production due to drought stress. Especially the cultivar "Toyoshiro" suitable for processing, has significant reduction in drought yield. Therefore, it is necessary to understand the mechanism of gene expression changes that occur in potato "Toyoshiro" plants and tubers during drought. METHODS AND
resultsSeed potatoes were split in half and one was used as a control plant (CT), and the other was used as a drought-stressed plant (DS). CT was watered daily, and DS watered off to mimic the weather conditions of the Tokachi-Obihiro region in 2021. These tubers were harvested at week 14 and the transcriptome was analyzed. DS plants showed 423 downregulated genes and 197 upregulated genes compared to CT. Factors related to cell wall modification, heat stress response, and phytosterol metabolism were detected among the genes whose expression changed. Moreover, the expression of "Abscisic acid and environmental stress-inducible protein TAS14 like (TAS14)," a molecule reported to be upregulated under drought stress, was also upregulated, and was upregulated expression in all strains that reproduced drought. The localization of this molecule in the nucleus and plasma membrane was confirmed in a mCherry-tagged TAS14 mutant line.
conclusionsOur findings contribute to understanding the survival strategy system of Japanese processing potatoes in response to drought stress.
