Genetic diversity of microbial eukaryotes (0.8-20 μm) and its seasonal variation in the pelagic and littoral zones were investigated from in Meiliang Bay of Lake Taihu in China. The water samples were collected in four seasons (February, May, August, and November). The genetic diversity of microbial eukaryote was analyzed by terminal restriction fragment length polymorphism (T-RFLP) of PCR-amplified partial eukaryotic 18S rRNA fragments. T-RFLP indicated that the microbial eukaryotic community compositions differed between the pelagic and littoral zone, but the difference decreased in warm seasons. The main environmental factors which affected on the variations of microbial eukaryotic community compositions in pelagic and littoral zones were revealed by multivariate statistical analysis. The canonical correspondence analysis between the genetic diversity of microbial eukaryotes and environmental factors revealed the trophic status had the most important impact on the microbial eukaryotic communities. Besides, a strong top-down regulation of microbial eukaryotes by zooplanktons was found in summer.
