mRNA transcriptome profiling of ileum in Japanese quails differing in their Phosphorus utilization. mRNA transcriptome profiling of ileum in Japanese quails differing in their Phosphorus utilization

Phosphorus (P) is essential for metabolism and homeostasis of living organisms. However, a major source of P in animal feed comes in a form of inositol phosphate (InsPx) which is inefficiently used by monogastrics animals due to an intrinsic minimal activity of endogenous phytase. This study aims to understand molecular mechanisms of P utilization in quails using an mRNA-Seq analysis of high- and low-P utilization quails selected from discordant sib pairs from different families. The results of differentially expressed genes and pathways related to P utility should serve as an important knowledge for field applications aiming to improve P utility in animal production and to reduce source of P pollution into environment.
