Genome-wide analysis of gene expression profiles during ear development of maize.
Article in Plant molecular biology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
In order to unravel the molecular mechanism of maize ear development, a microarray containing approximately 56,000 probes was used to monitor the gene expression profiles of ears at four developmental stages. The results showed that 2,794 genes, accounting for 5.0% of the total probes, changed significantly during ear development. Among the 2,794 genes, 1,844 genes differentially expressed during the spikelet differentiation phase, 836 genes during the floret primordium differentiation phase and 645 genes during the floret organ differentiation phase. Hierarchical clustering revealed that the differentially expressed genes had 9 major expression patterns. Based on Mips Functional Catalogue, 684 differentially expressed genes were grouped into at least one functional category, including metabolism (30.4%), protein related function (29.2%), biogenesis of cellular components (15.4%) and transcription (13.7%). The analysis revealed that the auxin signaling pathway play an important role in ear development. Moreover, regulation of some transcription factors may play a key role during ear development. RT-PCR and in situ hybridization for some selected genes validated our microarray data and supplied additional information on ear developmental processes.
