A systemic proteomic analysis of Populus chloroplast by using shotgun method.

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
The chloroplast is one of the most important organelles in plants. Proteomic investigations of chloroplasts have been undertaken for many herb plant species, but to date no such investigation has been reported for woody plant chloroplasts. In the present study we initiated a systematic proteomic study of Populus chloroplasts using a shotgun proteomic method. After isolation of chloroplasts and tryptic digestion of the proteins, the protein fragments were separated via HPLC using an SCX column, and the peptides were analyzed by LC-MS/MS; 119 proteins were successfully identified. Based on annotation information in the UniProtKB/Swiss-Prot database, these proteins were identified as being localized in the chloroplast thylakoid membrane, chloroplast stroma, chloroplast thylakoid lumen, and plastoglobules. Over 50% of all identified proteins were confirmed as chloroplast thylakoid proteins, and 85 are encoded by the chloroplast genome with the remaining proteins encoded by the nuclear genome. Based on functional annotation, these proteins were classified into four functional categories, including photosynthesis, redox regulation and stress, primary and secondary metabolism, transport and signaling. These data provide a valuable basis for further studies on photosynthesis in poplar species.
