海洋纤毛虫是无脊椎动物的单细胞寄生虫,通常感染宿主的肠道和体腔空间。位于顶端复合体树底部的海洋地衣为探索顶端复合体进化的早期阶段提供了机会。海洋纤毛虫的分类通常基于明显的摄食阶段(滋养体)的形态特征,并结合寄主关系和分子系统发育数据。其他生活期的形态特征,如孢子,也被用来告知分类学何时可以找到这样的阶段。由于形态特征的种内变异水平很高,加上分类上明确的相对较少的性状,重建Gregine进化史是具有挑战性的。本研究结合形态数据和小亚基rDNA序列的系统发育分析,描述和建立了一个新属和新种(Cuspisella ishikarienssn.(Gen.,n.sp.)从日本北海道采集的一种多倍体寄主的肠道中分离出的海洋石斑鱼。这一新种具有一组不寻常的形态特征,包括一个带刺的附着器,并位于分子系统学上的一个长分支上。此外,本研究还建立了一个新的分子系统发育位置,并揭示了一组新的感染多倍体寄主的海洋赤霉菌素。
Marine gregarines are unicellular parasites of invertebrates commonly found infecting the intestine and coelomic spaces of their hosts. Situated at the base of the apicomplexan tree, marine gregarines offer an opportunity to explore the earliest stages of apicomplexan evolution. Classification of marine gregarines is often based on the morphological traits of the conspicuous feeding stages (trophozoites) in combination with host affiliation and molecular phylogenetic data. Morphological characters of other life stages such as the spore are also used to inform taxonomy when such stages can be found. The reconstruction of gregarine evolutionary history is challenging, due to high levels of intraspecific variation of morphological characters combined with relatively few traits that are taxonomically unambiguous. The current study combined morphological data with a phylogenetic analysis of small subunit rDNA sequences to describe and establish a new genus and species (Cuspisella ishikariensisn. gen., n. sp.) of marine gregarine isolated from the intestine of a polynoid host (Lepidonotus helotypus) collected from Hokkaido, Japan. This new species possesses a set of unusual morphological traits including a spiked attachment apparatus and sits on a long branch on the molecular phylogeny. Furthermore, this study establishes a molecular phylogenetic position forLoxomorphacf.harmothoe, a previously described marine gregarine, and reveals a new group of gregarines that infect polynoid hosts.
