Robust expression and association of ZmCCA1 with circadian rhythms in maize.
Article in Plant cell reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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 plants, the circadian clock is an endogenous mechanism that controls a wide range of biological processes. To date, as one of the key world crops, little is known about the molecular mechanism and components of the circadian clock in maize (Zea mays). In this study, we characterized the CIRCADIAN CLOCK ASSOCIATED1 gene of maize (ZmCCA1), an ortholog of CCA1 in Arabidopsis thaliana (AtCCA1). Quantitative real-time PCR analysis revealed that ZmCCA1 was expressed in leaves and stem apex meristems in a rhythmic pattern under long day and short day conditions, and its peak gene expression appeared during the morning. ZmCCA1 transcripts accumulated in all tissues evaluated, with higher levels in tassels and ears. Additionally, the expression of another photoperiod gene ZmTOC1 peaked 12 h after dawn on long days and at 10 h after dawn on short days. Subcellular localization analysis revealed that the ZmCCA1 protein is directed to the cell nucleus. Overexpression of ZmCCA1 in Arabidopsis reduced the expression levels of downstream genes, including GIGANTEA (AtGI), CONSTANS (AtCO), and FLOWERING LOCUST (AtFT), and resulted in longer hypocotyls and delayed flowering. Taken together, our data suggest that ZmCCA1 may be a core component of the circadian clock in maize.
