Cover Story: Amoebozoa are assumed to encompass members with the largest genome sizes. Trichosphaerium is a polymorphic, multinucleate, marine amoeba with a complicated life cycle. Data demonstrate that Trichosphaerium sp. possesses complete meiosis toolkit genes. These genes are expressed in its life stages, including medium and large cells. The life cycle of Trichosphaerium sp. involves asexual processes via binary fission and the multiple fragmentation of giant cells, as well as sexual-like processes involving genes implicated in sexual reproduction and polyploidization. Our genomic data showed that Trichosphaerium populations maintain a species-level of intragenomic variation. Lateral gene transfer occurs between bacteria and giant viruses. The level of gene trafficking in Trichosphaerium is the highest within Amoebozoa and among the highest within microbial eukaryotes. View this paper
