How do microsporidia invade cells?
Microsporidia are obligate intracellular eukaryotic parasites that utilize a unique mechanism to infect host cells. One of the main characteristics of all microsporidia is that they produce spores containing an extrusion apparatus that consists of a coiled polar tube ending in an anchoring disc at the apical part of the spore. With appropriate conditions inside a suitable host, the polar tube i...
متن کاملHow Communities Evolve
In Ecology, there is active debate about the nature of changes in large-scale biological systems, such as communities or even the whole ecosystem. The question is, are changes in communities the simply result of the replacement and evolution of its species? Or on the contrary, community change as a body. According to Niles Eldredge (1996), who has been working with these questions during the la...
متن کاملHow Did T3S Evolve?
The injectisome has a common evolutionary origin with the bacterial flagellum, as suggested by the fact that the basal bodies of both nanomachines are similar and include many proteins with a significant similarity. Moreover, there are also functional similarities, such as the use of specific chaperones (5, 45, 104, 108, 138) or of molecular systems regulating the size of the external appendage...
متن کاملHow genes evolve
Many new genes evolve through gene duplication followed by rapid evolution. The rate of the evolutionary process was thought to depend on the interrelationships between a protein’s structure and function, and its biological role. Yuri Wolf et al. used a mathematical model to predict the variables that determine the evolutionary rates of change in genes from Drosophila, Aspergillus, and humans. ...
