Communicative & Integrative Biology, 2016 The chromalveolate hypothesis presents an attractively simple explanation for the presence of red algal-derived secondary plastids in 5 major eukaryotic lineages: “chromista” phyla, cryptophytes, haptophytes and ochrophytes; and alveolate phyla ...

Frontiers in Microbiology, 2014 Intracellular bacterial supply of essential amino acids is common among sap-feeding insects, thus complementing the scarcity of nitrogenous compounds in plant phloem. This is also the role of the two mealybug endosymbiotic systems whose genomes have been

Endosymbiosis and Eukaryotic Cell Evolution [PDF]
Current Biology, 2015 Understanding the evolution of eukaryotic cellular complexity is one of the grand challenges of modern biology. It has now been firmly established that mitochondria and plastids, the classical membrane-bound organelles of eukaryotic cells, evolved from bacteria by endosymbiosis.

Abstract All eukaryotes harbor one or more remnants of ancient bacterial-derived endosymbionts, all of which have experienced considerable reduction in genome size. The colonization of an alphaproteobacterium in the stem eukaryote ultimately became the mitochondrion, to which membrane bioenergetics were relocated from the plasma membrane

mBio, 2018 Endosymbiotic bacteria associated with eukaryotic hosts are omnipresent in nature, particularly in insects. Studying the bacterial side of host-symbiont interactions is, however, often limited by the unculturability and genetic intractability of the ...

The Symbiosome: Legume and Rhizobia Co-evolution toward a Nitrogen-Fixing Organelle?
Frontiers in Plant Science, 2018 In legume nodules, symbiosomes containing endosymbiotic rhizobial bacteria act as temporary plant organelles that are responsible for nitrogen fixation, these bacteria develop mutual metabolic dependence with the host legume.

Stochastic Fluctuations of the Facultative Endosymbiont Wolbachia due to Finite Host Population Size
Ecology and EvolutionMany insects and other animals host heritable endosymbionts that alter host fitness and reproduction. The prevalence of facultative endosymbionts can fluctuate in host populations across time and geography for reasons that are poorly understood.

Host-Encoded Aminotransferase Import into the Endosymbiotic Bacteria Nardonella of Red Palm Weevil
InsectsSymbiotic systems are intimately integrated at multiple levels. Host–endosymbiont metabolic complementarity in amino acid biosynthesis is especially important for sap-feeding insects and their symbionts. In weevil–Nardonella endosymbiosis, the final step

Frontiers in MicrobiologyEndosymbiotic bacteria (ESB) have important effects on their hosts, contributing to its growth, reproduction and biological functions. Although the effects of exogenous bacteria on the trap formation of nematode-trapping fungi (NTF) have been revealed ...

Endosymbiosis: Lessons in Conflict Resolution
PLoS Biology, 2004 Endosymbiotic bacteria live within a host species. There are many and diverse examples of such relationships, the study of which provides important lessons for ecology and ...
