摘要

Platyproteum是一个神秘的单型属,以前属于顶复合体亚,直到最近的系统基因组学研究表明它从色素/colpodellid (chropodellid)分类群和顶复合体亚分支的基部分化出来。在本研究中,用形态学和分子数据相结合的方法描述了一个新种,P. noduliferae n. sp.。此外,鞭毛器官的重建被提出,以表征鞭毛的存在,直到这项研究,这是一个未知的特征,为该属。利用rDNA序列进行的系统发育分析表明,结节假疟原虫是间日假疟原虫的姊妹种,从染色体和顶复合体基部分化而来。该研究提供了新的形态学数据,证实了Platyproteum在其他双鞭毛虫物种中的地位,有助于提高对Platyproteum的理解,以及一些海洋肺泡虫在过渡到专性寄生生活方式时所经历的进化变化。

Description of an Enigmatic Alveolate, Platyproteum noduliferae n. sp., and Reconstruction of its Flagellar Apparatus

Platyproteum is an enigmatic, monotypic genus formerly assigned to the Apicomplexa, until a recent phylogenomic study demonstrated that it diverged from the base of the chromerid/colpodellid (chrompodellid) taxa and apicomplexan clade. In the present study, a new species, P. noduliferae n. sp., is described using a combination of morphological and molecular data. Moreover, a reconstruction of the flagellar apparatus is presented to characterize the presence of flagella which was, until this study, an unknown trait for this genus. Phylogenetic analyses using rDNA sequences suggested that P. noduliferae n. sp. is a sister species of P. vivax, diverging from the base of chrompodellids and apicomplexans. This study provides new morphological data that corroborates the position of Platyproteum amongst other biflagellate species, contributing to an improved understanding of Platyproteum and the evolutionary changes undergone by some marine alveolates as they transitioned into obligate parasitic life styles.

期刊介绍: Protist is the international forum for reporting substantial and novel findings in any area of research on protists. The criteria for acceptance of manuscripts are scientific excellence, significance, and interest for a broad readership. Suitable subject areas include: molecular, cell and developmental biology, biochemistry, systematics and phylogeny, and ecology of protists. Both autotrophic and heterotrophic protists as well as parasites are covered. The journal publishes original papers, short historical perspectives and includes a news and views section.
