By a News Reporter-Staff News Editor at Biotech Business Week -- Investigators publish new report on Life Science Research. According to news reporting from Auburn, Alabama, by NewsRx journalists, research stated, "Catfish has a male-heterogametic (XY) sex determination system, but genes involved in gonadogenesis, spermatogenesis, testicular determination, and sex determination are poorly understood. As a first step of understanding the transcriptome of the testis, here, we conducted RNA-Seq analysis using high throughput Illumina sequencing."
The news correspondents obtained a quote from the research from Auburn University, "A total of 269.6 million high quality reads were assembled into 193,462 contigs with a N50 length of 806 bp. Of these contigs, 67,923 contigs had hits to a set of 25,307 unigenes, including 167 unique genes that had not been previously identified in catfish. A meta-analysis of expressed genes in the testis and in the gynogen (double haploid female) allowed the identification of 5,450 genes that are preferentially expressed in the testis, providing a pool of putative male-biased genes. Gene ontology and annotation analysis suggested that many of these male-biased genes were involved in gonadogenesis, spermatogenesis, testicular determination, gametogenesis, gonad differentiation, and possibly sex determination. We provide the first transcriptome-level analysis of the catfish testis."
According to the news reporters, the research concluded: "Our analysis would lay the basis for sequential follow-up studies of genes involved in sex determination and differentiation in catfish."
