Nuclear structure and function in the nucleated planctomycete bacterium Gemmata obscuriglobus: a third cell plan for living organisms? (2008-2010)
Abstract
The project aims to test the hypothesis that the planctomycete bacterium Gemmata obscuriglobus and relatives possesses a nuclear pore composed of proteins homologous to those of eukaryote nuclei (i.e. those of animals, plants, fungi and protists). Members of this species possess DNA-containing nuclear regions bounded by a 2-membrane envelope similar to those in yeast and human cell nuclei- we wish to determine whether these envelopes possess nuclear pores with similar structure to eukaryote pores, and whether they are composed of proteins closely related to those of eukaryotes.
