论文摘要: Peritrichia is a large and distinctive assemblage of ciliated protists that was first observed by Antonie van Leeuwenhoek over 340 years ago. In the last two decades the evolutionary relationships of this subclass have been increasingly debated as morphological and molecular analyses have generated contrasting conclusions. In this study, we provide genomic-scale data from 12 typical representatives. We combine taxon- and gene-rich phylogenomic analyses, with up to 151 genes (43,956 amino acid residues) from 18 freshwater, brackish and marine isolates in order to assess the systematics and evolutionary history of the Peritrichia. The main findings were: (1) the subclass Peritrichia originates from the end of the Proterozoic to the Cambrian; (2) the monophyletic Peritrichia is sister to the Peniculia (represented by Paramecium) within the class Oligohymenophorea; (3) spasmin plays a significant role in peritrich evolution: we detected the spasmin gene in target ciliates and traced the molecular evolution of spasmin, a key spasmoneme component, together with phylogenetic relationships and morphology of the peritrichs. These findings provide evidence that spasmin is an important molecule to illustrate the phylogenetic position of Peritrichia within the class Oligohymenophorea, the monophyly of Peritrichia, and the diverse and rapid evolution of sessilid peritrichs.
