Transient increase in the levels of γ-tubulin complex and katanin are responsible for reorientation by ethylene and hypergravity of cortical microtubules.

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 body shape of a plant is primarily regulated by orientation of cortical microtubules. γ-Tubulin complex and katanin are required for the nucleation and the severing of microtubules, respectively. Here we discuss the role of γ-tubulin complex and katanin during reorientation of cortical microtubules. 1-Aminocyclopropane-1-carboxylic acid (ACC), the immediate precursor of ethylene, modifies growth anisotropy of azuki bean epicotyls; it inhibits elongation growth and promotes lateral growth. The ACC-induced reorientation of cortical microtubules from transverse to longitudinal directions preceded the modification of growth anisotropy. The transcript level of γ-tubulin complex (VaTUG and VaGCP3) and katanin (VaKTN1) was increased transiently by ACC treatment. During reorientation of cortical microtubules by hypergravity, which also modifies growth anisotropy of shoots, the expression levels of both γ-tubulin complex and katanin genes were increased transiently. The increase in the number of the nucleated microtubule branch as well as the microtubule-severing activity via upregulation of γ-tubulin complex genes and katanin genes may be involved in the reorientation of cortical microtubules, and contribute to the regulation of the shape of plant body.
