Nature全文 PDF神经源性基板的脊椎动物出现前起源
The pre-vertebrate origins of neurogenic placodes
Nature · 2015
依据索引收录的作者摘要概括。
Summary based on the indexed author abstract.
主要发现 Key findings
海鞘 Ciona 的原基板外胚层受 BMP 抑制调控，表达 Six1/2 和 Eya，并产生兼具化学感觉与神经分泌特征的纤毛神经元。
Ciona has proto-placodal ectoderm regulated by BMP inhibition and expressing Six1/2 and Eya; it produces ciliated neurons with chemosensory and neurosecretory features.
结论 Conclusions
脊椎动物神经源性基板的部分发育程序可能早于脊椎动物本身出现。
Parts of the developmental program for vertebrate neurogenic placodes probably predate vertebrates.

主要发现 Key findings
玻璃海鞘基因组草图包含约一万六千个蛋白质编码基因。许多脊椎动物基因家族在海鞘中以较简单的形式存在；其谱系特有创新包括与细菌和真菌基因相关的纤维素代谢基因。
The Ciona intestinalis draft genome contains approximately 16,000 protein-coding genes. Many vertebrate gene families occur in simpler forms, while lineage-specific innovations include cellulose-metabolism genes related to bacterial and fungal genes.
结论 Conclusions
海鞘保留较简单的脊索动物祖先信号与发育基因组分，有助于重建脊椎动物基因组的起源及其后续基因家族扩张。
Ciona preserves a comparatively simple ancestral repertoire of chordate signaling and developmental genes, making it informative for reconstructing vertebrate genomic origins and subsequent gene-family expansion.
