Tick symbiosis

Current Opinion in Insect Science
As obligate blood-feeders, ticks serve as vectors for a variety of pathogens that pose threats on both human and livestock health. The microbiota that ticks harbor play important roles in influencing tick nutrition, development, reproduction, and vector.

Symbiosis Islands ☆

2013
A symbiosis island is a genomic island that confers upon the bacterium carrying it the ability to form a mutualistic relationship with a eukaryotic host. The symbiosis island of Mesorhizobium loti strain R7A (ICEMlSymR7A) is a 501.8-kb chromosomally integrated element that is able to excise and transfer by conjugation to nonsymbiotic mesorhizobia in ...

Hydrogenosomes and Symbiosis

2005
Hydrogenosomes are not the same. They evolved several times — independently — from mitochondria or the common ancestor of hydrogenosomes and mitochondria. This process, in general, involved the loss of the organellar genome together with the mitochondrial electron transport chain, and metabolic adaptations to anoxic environments such as the use of ...

Saltational symbiosis

Theory in Biosciences, 2010
Symbiosis has long been associated with saltational evolutionary change in contradistinction to gradual Darwinian evolution based on gene mutations and recombination between individuals of a species, as well as with super-organismal views of the individual in contrast to the classical one-genome: one organism conception.

Symbiosis

1997
The establishment of a permanent and obligate coexistence of genetic entities that were once capable of independent existence played an important part in the origin of the eukaryotes, and, if our earlier speculations are correct, in the origin of cells and chromosomes. In this chapter, we discuss other examples of symbiosis. The term is used to include
