Genome-wide identification of Aux/IAA gene family members in grape and functional analysis of VaIAA3 in response to cold stress.
Article in Plant cell reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
key messageTwenty-five VvIAA genes and eighteen VaIAA genes were identified from Pinot Noir and Shanputao, respectively. The overexpression of VaIAA3 in transgenic Arabidopsis increased cold tolerance by regulating auxin, ABA and ethylene signaling. Aux/IAA genes are key genes involved in regulating auxin signal transduction in plants. Although IAA genes have been characterized in various plant species, the role of IAA genes in grape cold resistance is unclear. To further explore the members of the Aux/IAA gene family in grape and their functions, in this study, using genomic data for Pinot Noir (Vitis vinifera cv. 'Pinot Noir') and Shanputao (Vitis amurensis), 25 VvIAA genes and 18 VaIAA genes were identified. The VaIAA genes presented different expression patterns at five different temperatures (28 ± 1 °C, 5 ± 1 °C, 0 ± 1 °C, -5 ± 1 °C, and -10 ± 1 °C) according to qRT‑PCR results. VaIAA3 was selected as a candidate gene for further functional analysis because of its high expression level under low-temperature stress. Subcellular localization experiments revealed that VaIAA3 was localized in the nucleus. Additionally, under 4 °C treatment for 24 h, relative expression level of VaIAA3, antioxidant enzyme activity, survival rate, and cold-responsive gene expression in three transgenic lines (OE-1, OE-2, OE-3) were greater, whereas relative electrolytic conductivity (REC), malondialdehyde (MDA) content and hydrogen peroxide (H
