Analysis of gene expression and histone modification between C4 and non-C4 homologous genes of PPDK and PCK in maize.

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
More efficient photosynthesis has allowed C4 plants to adapt to more diverse ecosystems (such as hot and arid conditions) than C3 plants. To better understand C4 photosynthesis, we investigated the expression patterns of C4 genes (C4PPDK and PCK1) and their non-C4 homologous genes (CyPPDK1, CyPPDK2, and PCK2) in the different organs of maize (Zea mays). Both C4 genes and non-C4 genes showed organ-dependent expression patterns. The mRNA levels of C4 genes were more abundant in leaf organ than in seeds at 25 days after pollination (DAP), while non-C4 genes were mainly expressed in developing seeds. Further, acetylation of histone H3 lysine 9 (H3K9ac) positively correlates with mRNA levels of C4 genes (C4PPDK and PCK1) in roots, stems, leaves, and seeds at 25 DAP, acetylation of histone H4 lysine 5 (H4K5ac) in the promoter regions of both C4 (C4PPDK and PCK1) and non-C4 genes (CyPPDK1, CyPPDK2, and PCK2) correlated well with their transcripts abundance in stems. In photosynthetic organs (stems and leaves), dimethylation of histone H3 lysine 9 (H3K9me2) negatively correlated with mRNA levels of both C4 and non-C4 genes. Taken together, our data suggest that histone modification was involved in the transcription regulation of both C4 genes and non-C4 genes, which might provide a clue of the functional evolution of C4 genes.
