The BnALMT1 Protein That is an Aluminum-Activated Malate Transporter is Localized in the Plasma Membrane.
Article in Plant signaling & behavior, 2007. 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
We have previously reported that Al-induces citrate and malate efflux from P-sufficient and P-deficient plants of rape (Brassica napus L.) and that P-deficiency alone could not induce this response. Further investigation showed that the transcript of two genes designated BnALMT1 and BnALMT2 is accumulated in roots by Al-treatment. Transgenic tobacco cells (Nicotiana tabacum) and Xenopus laevis oocytes expressing the BnALMT1 and BnALMT2 proteins released more malate than control cells in the presence of Al, indicating that the BnALMT genes encode an Al-activated malate transporter. The transgenic tobacco cells exposed to toxic level of Al grew better than control cells indicating that the genes can enhance Al-resistance of plant cells. In this study we showed the subcellular localization of BnALMT1 fused to the green fluoresce protein (GFP). The BnALMT1:: GFP construct was transiently expressed in protoplasts prepared from Arabidopsis leaves using the polyethylene glycol (PEG) method. The result showed that the BnALMT1 protein is localized in the plasma membrane. This provides further evidence that the BnALMT proteins facilitate the transport of malate across the plasma membrane (PM).
