The representatives of the archamoebian genus Pelomyxa are amoeboid anaerobic protists that inhabit fresh-water anoxic sediments, and most of them are usually multinucleate. The cytoplasm of these unicellular organisms is highly complicated and contains numerous vacuoles of different types, as well as a wide range of prokaryotic endocytobionts, agglomerations of glycogen, lipids, etc. Among the great variety of cytoplasmic structures in P.

With the development of molecular pharmacognosy, the advantages of DNA molecular markers in the identification of original plants of Chinese medicinal materials are becoming increasingly significant. To compensate for the limitations of existing markers in the quality supervision of Chinese medicinal materials, our team has independently designed a new molecular marker named DNA signature sequence(DSS). This marker is a nucleotide sequence that only appears in a specific taxonomic unit, with a length of 40 bp and high identification accuracy.

Background: Research has suggested an interaction between gut microbiota and sleep, yet the causal relationships between gut microbiota, metabolites, and sleep disorders remain unclear. This study aims to uncover these relationships.
Methods: We obtained genome-wide data for 196 gut microbiota species (N = 18,340), 1400 metabolites (N = 8299), and sleep disorders (N = 361,194).
