Class XI myosins are required for development, cell expansion, and F-Actin organization in Arabidopsis.

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 actomyosin system is conserved throughout eukaryotes. Although F-actin is essential for cell growth and plant development, roles of the associated myosins are poorly understood. Using multiple gene knockouts in Arabidopsis thaliana, we investigated functional profiles of five class XI myosins, XI-K, XI-1, XI-2, XI-B, and XI-I. Plants lacking three myosins XI showed stunted growth and delayed flowering, whereas elimination of four myosins further exacerbated these defects. Loss of myosins led to decreased leaf cell expansion, with the most severe defects observed in the larger leaf cells. Root hair length in myosin-deficient plants was reduced approximately 10-fold, with quadruple knockouts showing morphological abnormalities. It was also found that trafficking of Golgi and peroxisomes was entirely myosin dependent. Surprisingly, myosins were required for proper organization of F-actin and the associated endoplasmic reticulum networks, revealing a novel, architectural function of the class XI myosins. These results establish critical roles of myosin-driven transport and F-actin organization during polarized and diffuse cell growth and indicate that myosins are key factors in plant growth and development.
