Schmidingerella arcuata is an ecologically important tintinnid ciliate that has long-served as a model species in plankton trophic ecology. We present a partial micronuclear genome and macronuclear transcriptome resource for S. arcuata, acquired using single-cell techniques, and we report on pilot analyses including functional annotation and genome architecture. Our analysis shows major fragmentation, elimination, and scrambling in the micronuclear genome of S. arcuata. This work introduces a new non-model genome resource for the study of ciliate ecology and genomic biology, and provides a detailed functional counterpart to ecological research on S. arcuata.

纤毛弧菌Schmidingerella arcuata(Spirotrichea)的基因组和转录组分析相结合,揭示了DNA消除,加扰和倒置的模式。

Schmidingerella arcuata是一种在生态上很重要的丁香纤毛虫,长期以来一直是浮游生物营养生态学中的典范物种。我们提出了使用单细胞技术获得的弓形葡萄球菌的部分微核基因组和大核转录组资源,并且我们报告了包括功能注释和基因组结构在内的中试分析。我们的分析显示,圆弧链球菌的微核基因组中主要的片段化,消除和加扰。这项工作介绍了纤毛虫生态学和基因组生物学研究中的一个新的非模型基因组资源,并提供了详细的功能对应到生态研究S. arcuata
