1 · What the graph read from it

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.

2 · The registry

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

Sweet potato (Ipomoea batatas (L.) Lam.) is one of the most important root crops in the world. Initial formation and development of storage roots (SRs) are key factors affecting its yields. In order to study the molecular mechanism and regulatory networks of the SRs development process, we have analyzed root transcriptomes between the high and low starch content sweet potato accessions at three different developmental stages. In this study, we assembled 46,840 unigenes using Illumina paired-end sequencing reads and identified differentially expressed genes (DEGs) between two accessions. The numbers of DEGs were increased with the development of SRs, indicating that the difference between two accessions is enlarging with the maturation. DEGs were mainly enriched in starch biosynthesis, plant hormones regulatory, and genetic information processing pathways. Then, expression patterns of DEGs that are most significant and starch biosynthesis related were validated using qRT-PCR. Our results provide valuable resources to future study on molecular mechanisms of SRs development and candidate genes for starch content improvement in sweet potato.
