Construction of a Genomic Bacterial Artificial Chromosome (BAC) Library for the Prawn Macrobrachium rosenbergii and Initial Analysis of ZW Chromosome-Derived BAC Inserts.
Article in Marine biotechnology (New York, N.Y.), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Knowledge on sex determination has proven valuable for commercial production of the prawn Macrobrachium rosenbergii due to sex dimorphism of the male and female individuals. Previous studies indicated that prawn sex is determined by a ZW-ZZ chromosomal system, but no genomic information is available for the sex chromosome. Herein, we constructed a genomic bacterial artificial chromosome (BAC) library and identified the ZW-derived BAC clones for initial analysis of the sex chromosomal DNA sequence. The arrayed BAC library contains 200,448 clones with average insert size of 115.4 kb, corresponding to ∼ 4× coverage of the estimated 5.38 Gb genome. Based on a short female-specific marker, a Z- and a W-fragment were retrieved with the genomic walking method. Screening the BAC library using a ZW-specific marker as probe resulted in 12 positive clones. From these, a Z-derived (P331M17) and a W-derived (P122G2) BAC clones were randomly selected and sequenced by PacBio method. We report the construction of a large insert, deep-coverage, and high-quality BAC library for M. rosenbergii that provides a useful resource for positional cloning of target genes, genomic organization, and comparative genomics analysis. Our study not only confirmed the ZW/ZZ system but also discovered sex-linked genes on ZW chromosomes for the first time, contributing to a comprehensive understanding of the genomic structure of sex chromosomes in M. rosenbergii.
