MusaSAP1, a A20/AN1 zinc finger gene from banana functions as a positive regulator in different stress responses.

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
A20/AN1 zinc finger domain containing Stress Associated Proteins (SAP) are involved in diverse stress response pathways in plants. In the present study, a novel banana SAP gene, MusaSAP1, was identified from banana EST database and was subsequently characterized by overexpression in transgenic banana plants. Expression profiling in native banana plants showed that MusaSAP1 was up-regulated by drought, salt, cold, heat and oxidative stress as well as by treatment with abscisic acid. Cellular localization assay carried out by making a MusaSAP1::GFP fusion protein indicated that MusaSAP1 is incompletely translocated to nucleus. Copy number analysis performed using real time PCR and Southern blotting indicated that MusaSAP1 occurs in the banana genome in a single copy per 11 chromosome set. Transgenic banana plants constitutively overexpressing MusaSAP1 displayed better stress endurance characteristics as compared to controls in both in vitro and ex vivo assays. Lesser membrane damage as indicated by reduced malondialdehyde levels in transgenic leaves subjected to drought, salt or oxidative stress pointed towards significant role for MusaSAP1 in stress amelioration pathways of banana. Strong up-regulation of a polyphenol oxidase (PPO) coding transcript in MusaSAP1 overexpressing plants together with induction of MusaSAP1 by wounding and methyl jasmonate treatment indicated possible involvement of MusaSAP1 in biotic stress responses where PPOs perform major functions in multiple defense pathways.
