DEX1, a novel plant protein, is required for exine pattern formation during pollen development 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
To identify factors that are required for proper pollen wall formation, we have characterized the T-DNA-tagged, dex1 mutation of Arabidopsis, which results in defective pollen wall pattern formation. This study reports the isolation and molecular characterization of DEX1 and morphological and ultrastructural analyses of dex1 plants. DEX1 encodes a novel plant protein that is predicted to be membrane associated and contains several potential calcium-binding domains. Pollen wall development in dex1 plants parallels that of wild-type plants until the early tetrad stage. In dex1 plants, primexine deposition is delayed and significantly reduced. The normal rippling of the plasma membrane and production of spacers observed in wild-type plants is also absent in the mutant. Sporopollenin is produced and randomly deposited on the plasma membrane in dex1 plants. However, it does not appear to be anchored to the microspore and forms large aggregates on the developing microspore and the locule walls. Based on the structure of DEX1 and the phenotype of dex1 plants, several potential roles for the protein are proposed.
