We investigated soil protist communities across five sites representing two characteristic dryland habitats in Qatar: rawdha and sabkha. Altogether, 100 samples were collected during a single field campaign; DNA was subsequently extracted, ...
Comparative genomics reveals insights into the ultrafast Ca2+-dependent cell contraction in ciliates (Eukaryota, SAR, Alveolata) [0.03%]
比较基因组学揭示了刺胞动物门粒虫亚门泡藻纲细胞超快速钙依赖收缩的见解
Ying Zhang,Fasheng Liang,Chunying Xu et al.
Ying Zhang et al.
Certain ciliate taxa possess a Ca2+-dependent mechanism for ultrafast contraction, in addition to the more common adenosine triphosphate (ATP)-dependent process. In this study, we integrated omics data from 47 ciliate species, focusing on f...
Morphogenesis of the anaerobic ciliate Tropidoatractus levanderi (Ciliophora, Armophorea, Metopida), with notes on conjugation and molecular phylogeny [0.03%]
Tropidoatractus levanderi (纤毛门，无膜囊亚纲，斜口纲)的无氧纤毛虫的发生发育及其接合和分子系统进化研究
Xiaochen Feng,Wenbao Zhuang,Ran Li et al.
Xiaochen Feng et al.
Tropidoatractidae, a recently established anaerobic family of metopid ciliates, have not yet been examined from a morphogenetic perspective. In this study, the interphase morphology, morphogenesis during binary fission, and body and certain...
