The chimeric eukaryote: origin of the nucleus from the karyomastigont in amitochondriate protists.
We present a testable model for the origin of the nucleus, the membrane-bounded organelle that defines eukaryotes. A chimeric cell evolved via symbiogenesis by syntrophic merger between anExpand
Molecular phylogeny of parabasalids inferred from small subunit rRNA sequences, with emphasis on the Devescovinidae and Calonymphidae (Trichomonadea).
Small subunit rRNA sequences were obtained by polymerase chain reaction from trichomonad symbionts of termites that belong to the polymastigont Calonymphidae, including Snyderella tabogae, CalonymphaExpand
Molecular phylogeny of parabasalids with emphasis on the order Cristamonadida and its complex morphological evolution.
Parabasalia represents a complex assemblage of species, which recently received extensive reorganization. The newly created order Cristamonadida unites complex hypermastigids belonging to theExpand
Motility proteins and the origin of the nucleus
Hypotheses on the origin of eukaryotic cells must account for the origin of the microtubular cytoskeletal structures (including the mitotic spindle, undulipodium/cilium (so‐called flagellum) andExpand
“Imperfections and oddities” in the origin of the nucleus
Abstract  “Dual terminologies should be reserved for the exclusive use of those who prefer confusion to clarity.” L. R. Cleveland, 1963 We outline a plausible evolutionary sequence that led fromExpand
Swimming against the current.
On a bright August afternoon on the southern coast of Nova Scotia, we were zipping along Highway 3, the Lighthouse Route—Dolan at the wheel of the van, Margulis navigating, half a dozen students inExpand
Molecular Phylogenetic Position of the Genera Stephanonympha and Caduceia (Parabasalia) Inferred from Nuclear Small Subunit rRNA Gene Sequences
ABSTRACT. Nuclear small subunit (SSU) rRNA gene sequences were obtained by polymerase chain reaction from trichomonad symbionts of termites that belong to the Devescovinidae (Caduceia versatilis) andExpand
Spirochete and protist symbionts of a termite (Mastotermes electrodominicus) in Miocene amber
Extraordinary preservation in amber of the Miocene termite Mastotermes electrodominicus has led to the discovery of fossil symbiotic microbes. Spirochete bacteria and wood-digesting protists wereExpand

Abstract. At least 12 termite gut protists have been named because of their bacterial symbionts. Dozens more species are diagnosed by epi- and endosymbionts and more still have regular bacterialExpand
Centrioles and Kinetosomes: Form, Function, and Evolution
We review the literature on centrioles, kinetosomes, and other microtubule organizing centers (MTOCs) in animal, plant, and protist cells in the context of the Henneguy-Lenhossék theory of 1899. ThisExpand
