Arabidopsis thaliana MAP65-1 and MAP65-2 function redundantly with MAP65-3/PLEIADE in cytokinesis downstream of MPK4.
Article in Plant signaling & behavior, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 47 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
Plant cytokinesis occurs by the growth of cell plates from the interior to the periphery of the cell. These dynamic events in cytokinesis are mediated by a plant-specific microtubule (MT) array called the phragmoplast, which consists of bundled antiparallel MTs between the two daughter nuclei. The NACK-PQR pathway, a NACK1 kinesin-like protein and mitogen activated protein kinase (MAPK) cascade, is a key regulator of plant cytokinesis through the regulation of phragmoplast MTs. The MT-associated protein MAP65 has been identified as one of the structural components of MT assays involved in cell division, and we recently showed that Arabidopsis AtMAP65-3/PLEIADE (PLE) is a substrate of MPK4 that is a component of the NACK-PQR pathway in Arabidopsis. Here we show that AtMAP65-1 and AtMAP65-2 are also phosphorylated by MPK4. AtMAP65-1 and AtMAP65-2 that localize to the phragmoplast were phosphorylated by MPK4 in vitro. Although mutants of the Arabidopsis AtMAP65-1 and AtMAP65-2 genes exhibited a wild-type phenotype, double mutations of AtMAP65-3 and AtMAP65-1 or AtMAP65-2 caused more severe growth and cytokinetic defects than the single atmap65-3/ple mutation. These results suggest that AtMAP65-1 and AtMAP65-2 also function in cytokinesis downstream of MPK4.
