Global gene expression profiling by RNA-Sequencing (RNA-Seq) was introduced in 2004 with the advent of next generation sequencing technologies and has made a revolutionary impact on transcriptome analysis. When compared to the traditional microarray technologies. RNA-Seq has major advantages such as a higher dynamic range, a precise unbiased quantification of transcripts and a comprehensive coverage of all expressed sequences in a given tissue. Besides transcript quantification, RNA-Seq is utilized for comparison of transcriptomes, mapping the 5' and 3' boundaries of mRNA and introns, finding of novel exons, study of allele-specific expression, SNP discovery, study of non-coding RNA and de novo gene model building. Two major challenges faced with the RNA-Seq are the differences in sequencing technologies and bioinformatics analysis. Recently, RNA-Seq technology has increasingly been used in livestock, wild and aquatic animal studies to measure gene expression analysis and SNP discovery. This review summarizes the capabilities and challenges of RNA-Seq and the impact of this technology on animal genetics research. (C) 2014 Elsevier B.V. All rights reserved.
