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

Non-coding RNA (ncRNA)-based SSR markers are highly useful in molecular breeding as ncRNAs play a significant role in gene regulation. In the present study, for the first time in coconut, we have identified 597 ncRNA-derived SSR markers, including 509 long non-coding RNASSRs (lncRNASSRs) and 88 micro RNASSRs (miRNASSRs). Of these, 20 primers (10 each from lncRNA-SSR and miRNA-SSR) were selected, screened on 6 coconut accessions, and 50% produced polymorphic fragments. These 10 polymorphic primers were used for genotyping 96 palms of 16 coconut accessions, comprising eight tall and dwarf accessions each. The number of alleles ranged from 2 to 9 per SSR marker, with an average of 4.6 alleles per locus. The average heterozygosity and Shannon index were 0.5 and 1.1, respectively, suggesting that ncRNA-SSRs show high polymorphism level. Distance-based cluster analyses revealed that all the tall and dwarf accessions were differentiated and grouped in different clusters. The study demonstrates the usefulness of ncRNA-based SSR markers for assessing genetic diversity and genetic improvement in coconut.
