基因组分析颠覆了脊索动物的进化史,将被囊类动物视为脊椎动物的姐妹群。这种分类学上的重新排列提出了关于被囊动物/脊椎动物祖先出现的问题。表征被囊动物和脊椎动物独特共有的发育基因是一种很有前途的方法,可以解释获得新的祖先特征背后的发育转变。基质糖蛋白纤维连接蛋白(FN)一直被认为是脊椎动物特有的基因,在脊椎动物胚胎发育中起着重要的指导作用。然而,最近的计算预测的orthopathic "脊椎动物样" Fn基因的基因组中的被囊动物,玻璃海鞘,挑战这一观点,表明Fn可能已经出现在共享的被囊动物/脊椎动物的祖先。在这里,我们验证了存在的被囊Fn直系同源物。转基因报告分析用于表征玻璃海鞘Fn增强子驱动脊索中的表达。脊索谱系中的靶向敲低表明FN是适当的会聚延伸所需的。这些研究结果表明,收购Fn与脊椎动物/被囊动物祖先脊索形态发生的改变。本文的在线版本(doi:10.1186/s13227 - 016 - 0056 - 4)包含补充材料,可供授权用户使用。
Genomic analysis has upended chordate phylogeny, placing the tunicates as the sister group to the vertebrates. This taxonomic rearrangement raises questions about the emergence of a tunicate/vertebrate ancestor. Characterization of developmental genes uniquely shared by tunicates and vertebrates is one promising approach for deciphering developmental shifts underlying acquisition of novel, ancestral traits. The matrix glycoprotein Fibronectin (FN) has long been considered a vertebrate-specific gene, playing a major instructive role in vertebrate embryonic development. However, the recent computational prediction of an orthologous “vertebrate-like” Fn gene in the genome of a tunicate, Ciona savignyi, challenges this viewpoint suggesting that Fn may have arisen in the shared tunicate/vertebrate ancestor. Here we verify the presence of a tunicate Fn ortholog. Transgenic reporter analysis was used to characterize a Ciona Fn enhancer driving expression in the notochord. Targeted knockdown in the notochord lineage indicates that FN is required for proper convergent extension. These findings suggest that acquisition of Fn was associated with altered notochord morphogenesis in the vertebrate/tunicate ancestor.
