Integrated analysis of mRNA-seq and miRNA-seq in calyx abscission zone of Korla fragrant pear involved in calyx persistence.
Article in BMC plant biology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundThe objective of this study was to characterize molecular mechanism of calyx persistence in Korla fragrant pear by transcriptome and small RNA sequencing. Abscission zone tissues of flowers at three stages (the first, fifth and ninth days of the late bloom stage), with 50 mg/L GA
resultsThrough association analysis of transcriptome and small RNA sequencing, mRNA-miRNA network was conducted. Compared calyx persistence groups with calyx abscission groups during the same stage, 145, 56 and 150 mRNA-miRNA pairs were obtained in C_1 vs T_1, C_5 vs T_5 and C_9 vs T_9, respectively; When C_1 compared with C_5 and C_9, 90 and 506 mRNA-miRNA pairs were screened respectively, and 255 mRNA-miRNA pairs were obtained from the comparison between C_5 and C_9; When T_1 compared with the T_5 and T_9, respectively, 206 and 796 mRNA-miRNA pairs were obtained, and 383 mRNA-miRNA pairs were obtained from the comparison between T_5 and T_9. These mRNAs in miRNA-mRNA pairs were significantly enriched into the terpenoid backbone biosynthesis, photosynthesis - antenna proteins, porphyrin and chlorophyll metabolism, carotenoid biosynthesis, zeatin biosynthesis and plant hormone signal transduction. In addition, we obtained some key genes from miRNA-mRNA pairs that may be associated with calyx abscission, including protein phosphatase 2C (psi-miR394a-HAB1), receptor-like protein kinase (psi-miR396a-5p-HERK1), cellulose synthase-like protein D3 (psi-miR827-CSLD3), beta-galactosidase (psi-miR858b-β-galactosidase), SPL-psi-miR156j/157d, abscisic acid 8'-hydroxylase 1 (psi-miR396a-5p-CYP707A1) and auxin response factor (psi-miR160a-3p-ARF6, psi-miR167d-ARF18, psi-miR167a-5p-ARF25), etc.
conclusionBy integrated analysis mRNA and miRNA, our study gives a better understanding of the important genes and regulation pathway related to calyx abscission in Korla fragrant pear. We have also established the network of miRNA-mRNA pairs to learn about precise regulation of miRNA on calyx abscission.
