Plastid genome evolution in serial secondary plastids of a green-colord dinoflagellate

本研究对绿色甲藻Lepidodinium的质体基因组进行了测序，以追溯其质体的起源和进化。通过次代测序分析，获得了几乎完整的质体基因组序列。通过大型质体基因数据和比较基因组学的系统发育分析表明，鳞藻质体来源于一种与足藻科密切相关的绿藻，并且在获得质体后发生了激烈的基因组重排。

In this study, in order to retrace origin and evolution of plastids in the green colored dinoflagellate Lepidodinium, its plastid genome was sequenced. Nearly complete sequence of the plastid genome was obtained by the next generation sequencing analysis. Phylogenetic analysis with a large plastid gene dataset and comparative genomics revealed that the Lepidodinium plastids are derived from a green alga closely related to Pedinophyceae and drastic genome rearrangement has been occurred after the plastid acquisition.
