...Bungo Akiyoshi ABSTRACT Eukaryotes possess two different mechanisms to transmit genetic material – mitosis and meiosis. Because mitosis is universal in all present-day eukaryotes, it has been widely assumed, despite the absence of definitive evidence, that meiosis evolved from mitosis during...

...Emily K. Herman; Giselle Walker; Mark van der Giezen; Joel B. Dacks Endosomal sorting complexes required for transport (ESCRTs) are heteromeric protein complexes required for multivesicular body (MVB) morphogenesis. ESCRTs I, II, III and III-associated are ubiquitous in eukaryotes and presumably...

...Joel B. Dacks; Mark C. Field The emergence of an endomembrane system was a crucial stage in the prokaryote-to-eukaryote evolutionary transition. Recent genomic and molecular evolutionary analyses have provided insight into how this critical system arrived at its modern configuration. The apparent...
