Paracoccus and Rhodopseudomonas are unusual among bacteria in having a majority of the biochemical features of mitochondria; blue-green algae have many of the features of chloroplasts. The theory of serial endo-symbiosis proposes that a primitive eukaryote successively took up bacteria and blue-green algae to yield mitochondria and chloroplasts respectively. Possible characteristics of transitional forms are indicated both by the primitive amoeba, Pelomyxa, which lacks mitochondria but contains…

The endosymbiotic origin of chloroplasts

The Origin, Losses and Gains of Chloroplasts

More and more evidence supports the alternative view that no secondary symbiosis was involved, and that the euglenoid chloroplast is simply the earliest diverging of all and arose directly from the same cyanobacterium as all other chloroplasts.

CHLOROPLAST EVOLUTION—ANCIENT AND MODERN

If chloroplasts did indeed evolve from photosynthetic symbionts, then algal phylogeny must take account not only of the individual characteristics of the host cells and their Symbionts but also of modifications of these characteristics arising from interactions between host and symbiont.

Origins of Mitochondria and Plastids

This introductory chapter provides an overview of the primary endosymbiotic origins of mitochondria and plastids, focusing on advances coming from the latest comparative genomic and proteomic investigations.

What’s Eating Eu? The Role of Eukaryote/Eukaryote Endosymbioses in Plastid Origins

The plastids of green algae, and their descendants the land plants, clearly arose from a cyanobacterium-like endocytobiont that was reduced to organelle status (exogenosome) within the former eukaryotic host, and a hypothesis for targeting is presented.

The highly reduced genome of an enslaved algal nucleus

Complete sequences for all three nucleomorph chromosomes from the cryptomonad Guillardia theta are reported, offering a means for studying eukaryotic chromosome replication, segregation and evolution.

The many twists and turns of plastid evolution each represent major evolutionary transitions, and each offers a glimpse into how genomes evolve and how cells integrate through gene transfers and protein trafficking.

The assignment of S. didemni to any of the established algal divisions presents a major taxonomic problem because these ascidian symbionts are apple green and contain no detectable bilin pigments.

NUCLEAR ENVELOPE-CHLOROPLAST RELATIONSHIPS IN ALGAE

A double-membraned outer envelope appears to be present outside the chloroplasts of the Phaeophyta and Euglenophyta, but seems to be absent in the other groups of algae.

The colonization of host cells by modern symbionts is surveyed, and it is surmised that encirclement by a vacuolar membrane would only disappear in the later stages of the evolution of intracellular symbiosis.

CELL DIVISION IN CYANOPHORA PARADOXA

Mitosis in the nucleus of Cyanophora paradoxa is shown to be generally typical of other eukaryotic cells, and observations indicate that the host cell of the symbiotic pair cannot be considered as a dinoflagellate as had been previously suggested.

Anaerobiosis and symbiosis with bacteria in free-living ciliates.

Most of the anaerobic ciliates harbor a flora of ecto- and endosymbiotic bacteria as demonstrated by transmission and scanning electron micrographs and it is speculated that the bacteria may utilize the metabolic end products of the protozoa for growth and energy yielding processes.

The complex cell boundary is described and the convolutions of the outer layer are believed to be connected either with the synthesis or attachment of the narrow mucilagenous sheath, which appear to be concerned with the cellular photosynthetic mechanism.
