Overlapping functions of the four class XI myosins in Arabidopsis growth, root hair elongation, and organelle motility.

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
Flowering plants have evolved multigene families of the class XI myosin motors, the functions of which remain poorly understood. Here, we investigated functional profiles of the Arabidopsis myosins that belong to two paralogous pairs, XI-K/XI-1 and XI-2/XI-B, using single and double gene-knockout mutants. It was found that the myosins XI-K, XI-2, and XI-B, but not XI-1 have overlapping and additive roles in the root hair elongation. A nonidentical set of the three myosins, XI-K, XI-1, and XI-2, exhibited partially redundant and additive roles in the transport of Golgi stacks, peroxisomes, and mitochondria. Conspicuously, the double xi-k/1 knockout plants that showed the largest cumulative reduction of the organelle velocities also exhibited a stunted plant growth and reduced fecundity phenotype. Collectively, these results suggest that the rapid, myosin-powered organelle trafficking is required for the optimal plant growth, whereas a distinct myosin function, presumably the vesicular transport, is involved in elongation of the root hairs. In addition, our data imply that the myosin gene duplication in plants has been followed by a gradual functional specialization of the resulting pairs of myosin paralogs.
