Overexpression of VaPAT1, a GRAS transcription factor from Vitis amurensis, confers abiotic stress tolerance in Arabidopsis.
Article in Plant cell reports, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 79 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 messageVaPAT1 functions as a stress-inducible GRAS gene and enhanced cold, drought and salt tolerance in transgenic Arabidopsis via modulation of the expression of a series of stress-related genes. The plant-specific GRAS transcription factor family regulates diverse processes involved in plant growth, development and stress responses. In this study, VaPAT1, a GRAS gene from Vitis amurensis was isolated and functionally characterized. Sequence alignment and phylogenetic analysis showed that VaPAT1 has a high sequence identity to CmsGRAS and OsCIGR1, which belong to PAT1 branch of GRAS family and function in stress resistance. The transcription of VaPAT1 was markedly induced by stress-related phytohormone abscisic acid (ABA) and various abiotic stress treatments such as cold, drought and high salinity, however, it was repressed by exogenous gibberellic acid (GA) application. Overexpression of VaPAT1 increased the cold, drought and high salinity tolerance in transgenic Arabidopsis. When compared with wild type (WT) seedlings, the VaPAT1-overexpression lines accumulated higher levels of proline and soluble sugar under these stress treatments. Moreover, stress-related genes such as AtSIZ1, AtCBF1, AtATR1/MYB34, AtMYC2, AtCOR15A, AtRD29A and AtRD29B showed higher expression levels in VaPAT1 transgenic lines than in WT Arabidopsis under normal growth conditions. Together, our results indicated that VaPAT1 functions as a positive transcriptional regulator involved in grapevine abiotic stress responses.
