    General Introduction:  

    The laboratory of Protozoan Functional Genomics at the Institute of Hydrobiology (IHB), Chinese Academy of Sciences (CAS) was founded in 2009, and tracked from the well-reputed research group of Protozoan taxonomy and ecology which was founded by academician Jiaji WANG and further developed by academician Yunfen SHEN and Prof. Yuhe YU.  

    Our research interests focus on the functional genomics of model organism, Tetrahymena and other protozoan species, with the aims of: 1)investigating the unique mechanisms of molecular evolution, functional divergence and ecological adaptation in the unicellular eukaryotes at the genomics level; 2)studying the basic metabolism pathways or regulation networks that are conserved among the eukaryotic organisms.

    Currently, there are four main research directions:  

    1)Evolutionary Genomics & Phylogenomics of Protozoan —— based on sequencing and analyzing the omics data from typical species of ciliate groups and free-living/parasitic/mutualistic ciliates, studying the phylogeny and adaptive evolution among ciliates, further discussing the evolutionary biology of unicellular eukaryotes;  

    2)Evolutionary & Ecological Functional Genomics (EEFG) of Tetrahymena —— based on sequencing and analyzing the omics data from more than ten species among genus Tetrahymena, studying the comparative genomics and the experimental evolutionary genomics of Tetrahymena, further discussing the speciation, ecological adaptation and reproductive evolution etc. of unicellular eukaryotes;  

    3)Epigenomics of Tetrahymena —— based on the omics data and experimental biological technique, studying the functions of histone modification and Small RNA on DNA replication and meiosis, further discussing the epigenetic mechanism involved in nuclear events of eukaryotes; 

    4)Genetic Engineeringof Tetrahymena —— based on the Tetrahymena expression system and genetic resources of ciliates, developing the biosensor and bioreactor for monitorring/degrading the pollutants and producing the vaccin of ciliate diseases.
