Alternative Endosymbiosis


alternative Endosymbiosis

for the antiquity of the divergences that separate the deep red algal lineages. The Nephroselmidophyceae includes flagellates with complex scale covering, and is possibly one of the earliest diverging chlorophytan lineages (Turmel., 2009). G., Miyata,., Kikuchi,., Oliveira,. Photosynthetic apparatus, the presence of two photosystems (PS I and PS II) in which a central chlorophyll a molecule is oxidized; electrolysis of H2O as electron donor and release of O2; similarities in the electron transport chains; shared phycobilisomes between Cyanobacteria and Glaucophyta and Rhodophyta. Green evolution and dynamic adaptations revealed by genomes of the marine picoeukaryotes Micromonas. Together with some undescribed coccoids (ccmp1205 clade these prasinophytes might form the closest sister lineages of the core chlorophytes, although strong support is lacking (Marin Melkonian, 2010). Philosophical Transactions of the Royal Society B: Biological Sciences 361, 903-915. Comparative analysis of the complete plastid genome sequence of the red alga Gracilaria tenuistipitata var. These proteins sit inside the mitochondrions inner membrane, which is repeatedly folded like ruched fabric.

Concatenation: Dataset in which sequence information of multiple genes is combined in a single dataset and analyzed together assuming all genes share a common history. The authors offer no mechanism or process by which these cyanobacteria incorporated into another prokaryote and eventually became an organelle of a plant cell working in concert with the other organelles within the cell to make a fully functional, replicating cell. Plant Physiology 137, 460-474. Many species are photosynthetic symbionts with lichen fungi, various protists, invertebrates and plants; others have evolved a free-living or parasitic heterotrophic life style (Friedl Rybalka, 2011; Leliaert., 2012). Our very existence, and that of every animal, plant and fungus, depended on an ancient partnership, forged a few billion years ago, which gave our ancestors access to unparalleled supplies of energy and allowed them to escape from the shackles of simplicity. Molecular Biology and Evolution 12, 415-420. However, many uncertainties remain, especially about the deepest branches of the green plants. Large-Scale Phylogenomic Analyses Indicate a Deep Origin of Primary Plastids within Cyanobacteria. There is a general consensus that photosynthesis was acquired by eukaryotes through endosymbiosis, resulting in the enslavement of a cyanobacterium to become a plastid. Their cells are large, structured, and filled with many internal compartments. Origin of plastids: primary endosymbiosis.

However, the scenario they propose, which on the surface seems simpler and therefore much more likely, is not. The TUC clades include a wide variety of morphological forms and eco-physiological features.
