The term mycorrhiza is rooted from two Greek words myco meaning fungi and Rrhiza meaning root and its’ meaning in reality means symbiosis between a fungus and root.

Current Opinion in Plant Biology, 2003
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 ...

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.

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 ...

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

Trends in Ecology & Evolution, 2012
In the Origin of Species, Darwin struggled with how continuous changes within a species lead to the emergence of discrete species. Molecular analyses have since identified nuclear genes and organelles that underpin speciation. In this review, we explore the microbiota as a third genetic component that spurs species formation.

INDUSTRIAL SYMBIOSIS: Literature and Taxonomy
, 2000▪ Abstract Industrial symbiosis, as part of the emerging field of industrial ecology, demands resolute attention to the flow of materials and energy through local and regional economies. Industrial symbiosis engages traditionally separate industries in a

The purpose of this article is to re-address the vision of human-computer symbiosis as originally expressed by J.C.R. Licklider nearly a half-century ago and to argue for the relevance of this vision to the field of cognitive informatics. We describe this vision, place it in some historical context relating to the evolution of human factors research ...

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.

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.
