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

backgroundThe Ogura-type male sterile cytoplasm is commonly used in Brassicaceae plants, but its sterility mechanism still requires further investigation.

resultsThe flower buds of Ogura CMS line ZJCMS1A and its maintainer line ZJCMS1B based on their length < 2 mm, 2 mm-3 mm, 3 mm-4 mm, grouped A2, A3, A4 and B2, B3, B4, respectively. Anthers were excised from flower buds of each group for transcriptome and metabolome sequencing. Differential comparison analysis, Venn analysis, Multi-omics Integration KEGG enrichment analysis, and pathway network analysis were performed on the data from different groups. The results showed that the abnormal propanoate metabolic pathway in ZJCMS1A was closely related to pollen abortion. The content of 3-hydroxypropionic acid (3-HP) in the propanoate metabolic pathway was higher in ZJCMS1A than in ZJCMS1B in the three comparisons A2 vs B2, A3 vs B3, and A4 vs B4. Furthermore, the content of 3-HP in ZJCMS2A flower buds was also higher than in ZJCMS2B. Quantification of 3-HP content revealed that the content in the stems, leaves, and flower buds of ZJCMS1A was higher than that in the corresponding tissues of ZJCMS1B. The 3-HP content in the flower buds of ZJCMS1A was 8.1% higher than that in ZJCMS1B. Treatment of rapeseed plants with 20 mM and 50 mM 3-HP showed that starch accumulation in pollen grains was affected.

conclusionsThese results indicated that pollen abortion in Ogura-type CMS is closely related to abnormalities in the propanoate metabolic pathway, particularly the abnormal accumulation of 3-HP, which may participate in the pollen abortion process.
