In recent years, the major focus in nodulation research has been on the genetic dissection of Nod-factor signaling. Components of this pathway appear to be shared with signaling processes that are induced during the formation of mycorrhiza. With the cloning of orthologs of the NIN and DMI2 genes from several legumes, the molecular characteristics of ...

Parasitic protozoa and bacteria transmitted by vector insects and ticks resist destruction in the intermediate host, possibly through the possession of antigens similar to those of the host. There is no evidence that symbiotic microorganisms have evolved similar eclipsed antigens.

The American Naturalist, 1997
A tentative outline of concepts is proposed for the evolutionary genetics of symbiosis. There are three main topics. The first concerns the tension between the integrative and disruptive forces of kin selection. Kin selection can be disruptive because competition among close relatives favors dispersal and a reduction in relatedness among neighbors. Kin

Microbial Symbiosis: A Network towards Biomethanation.
Trends in Microbiology, 2020Biomethanation through anaerobic digestion (AD) is the most reliable energy harvesting process to achieve waste-to-energy. Microbial communities, including hydrolytic and fermentative bacteria, syntrophic bacteria, and methanogenic archaea, and their ...

Medical Hypotheses, 1994
Preservation of the identity of DNA is the ultimate goal of multicellular organisms. An abnormal DNA sequence in cells within an individual means its parasitic nature in cell society as shown in tumors. Somatic gene arrangement and gene mutation in development may be considered as de novo formation of parasites.

American Journal of Psychiatry, 1972
The author describes a symbiotic syndrome in adults that, although similar to the syndrome in children, has some distinguishing features. He cites four case examples. He believes it is useful to be precise in distinguishing symbiosis from other chronic psychotic and borderline states because of specific differences in therapy.

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 ...

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.

NUTRITION may be taken to include all those processes by which chemical substances essential to the life of a given species, be it plant or animal, become available for anabolism. Thus in plants, nutrition includes photosynthesis and root absorption, as well as the processes of digestion which occur in animals and insectivorous plants.
