title: Notochord-specific transcriptome in Atlantic salmon using RNA-seq
design: A total of 9 RNA libraries were prepared from notochord tissue dissected out from three developmental stages in Atlantic salmon larva, right after hatching (510, 610 and 710 day degrees). Pooled pure notochord samples were isolated from three segments along the anterior-posterior body axis and labeled as anterior, mid, posterior. This study reveal the dynamtic transcriptome of the notochord during early development prior to the formation of vertebra in Atlantic salmon. Expression patterns of essential structural and signalling genes, as well as pathways, provide clues to the segmentation of the notochord and mineralization of the notochord sheath.
