Spatiotemporal seed development analysis provides insight into primary dormancy induction and evolution of the Lepidium delay of germination1 genes.

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
Seed dormancy is a block to the completion of germination of an intact viable seed under favorable conditions and is an adaptive and agronomically important trait. Thus, elucidating conserved features of dormancy mechanisms is of great interest. The worldwide-distributed genus Lepidium (Brassicaceae) is well suited for cross-species comparisons investigating the origin of common or specific early-life-history traits. We show here that homologs of the seed dormancy-specific gene delay of germination1 (DOG1) from Arabidopsis (Arabidopsis thaliana) are widespread in the genus Lepidium. The highly dormant Lepidium papillosum is a polyploid species and possesses multiple structurally diversified DOG1 genes (LepaDOG1), some being expressed in seeds. We used the largely elongated and well-structured infructescence of L. papillosum for studying primary dormancy induction during seed development and maturation with high temporal resolution. Using simultaneous germination assays and marker protein expression detection, we show that LepaDOG1 proteins are expressed in seeds during maturation prior to dormancy induction. Accumulation of LepaDOG1 takes place in seeds that gain premature germinability before and during the seed-filling stage and declines during the late maturation and desiccation phase when dormancy is induced. These analyses of the Lepidium DOG1 genes and their protein expression patterns highlight similarities and species-specific differences of primary dormancy induction mechanism(s) in the Brassicaceae.
