Thermotolerance of isolated mitochondria associated with heat shock proteins.
Article in Plant physiology, 1989. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Mitochondria isolated from 2-day-old etiolated soybean (Glycine max) seedlings which had been subjected to various heat shock treatments, i.e. (A) 28 degrees C (2 h), (B) 38 degrees C (2 h), (C) 38 degrees C (2 h)-42.5 degrees C (0.5 h), and (D) 38 degrees C (2 h)-42.5 degrees C (0.5 h)-28 degrees C (4 h), were monitored for O(2) uptake using an oxygen electrode. Mitochondria isolated after all four heat shock treatments were active in O(2) consumption at 28 degrees C in response to succinate and ADP (derived P/O ratios were 1.6, 1.7, 1.3, and 1.3, respectively.) The mitochondria from all four treatments were also active in O(2) uptake at 42.5 degrees C. However, only mitochondria isolated after treatment (C) were tightly coupling at 42.5 degrees C (derived ADP/O ratio was about 1.4). Combined with our earlier findings on the subcellular localization of heat shock proteins, our present data demonstrate that association of heat shock proteins with mitochondria by treatment (C) enables them to phosphorylate at 42.5 degrees C (i.e. they become thermotolerant). Isolated mitochondria from treatment (C) and treatment (A) were compared by electron microscopy. They appeared to be very similar and no significant ultrastructural differences were noted.
