Changes in chloroplast ultrastructure in some high-alpine plants: adaptation to metabolic demands and climate?
Article in Protoplasma, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
The cytology of leaf cells from five different high-alpine plants was studied and compared with structures in chloroplasts from the typical high-alpine plant Ranunculus glacialis previously described as having frequent envelope plus stroma protrusions. The plants under investigation ranged from subalpine/alpine Geum montanum through alpine Geum reptans, Poa alpina var. vivipara, and Oxyria digyna to nival Cerastium uniflorum and R. glacialis. The general leaf structure (by light microscopy) and leaf mesophyll cell ultrastructure (by transmission electron microscopy [TEM]) did not show any specialized structures unique to these mountain species. However, chloroplast protrusion formation could be found in G. reptans and, to a greater extent, in O. digyna. The other species exhibited only a low percentage of such chloroplast structural changes. Occurrence of protrusions in samples of G. montanum and O. digyna growing in a mild climate at about 50 m above sea level was drastically reduced. Serial TEM sections of O. digyna cells showed that the protrusions can appear as rather broad and long appendices of plastids, often forming pocketlike structures where mitochondria and microbodies are in close vicinity to the plastid and to each other. It is suggested that some high-alpine plants may form such protrusions to facilitate fast exchange of molecules between cytoplasm and plastid as an adaptation to the short, often unfavorable vegetation period in the Alps, while other species may have developed different types of adaptation that are not expressed in ultrastructural changes of the plastids.
