Reproductive parasitism: maternally inherited symbionts in a biparental world.
Most species of insect, and many other plants and animals, carry maternally heritable microorganisms-viruses, bacteria, unicellular eukaryotes, and fungi that pass from a female host to her progeny. Maternal inheritance establishes a correlation between the fitness of symbiont and host female, which can select for the symbiont to contribute to host fitness. Nevertheless, its lack of transmissio...
متن کاملUpdate on Nutrient Sharing between Symbionts Nutrient Sharing between Symbionts
In this review, we consider the exchange of nutrients between the host plant and the bacterial microsymbiont in nitrogen-fixing legume root nodules. During nodule formation, the host tissues and the bacterial microsymbiont develop in response to each other to form a specialized tissue that maintains an environment where nitrogen fixation can occur (Brewin, 2004; Mergaert et al., 2006; Prell and...
متن کاملHonor thy symbionts.
Our intestine is the site of an extraordinarily complex and dynamic environmentally transmitted consortial symbiosis. The molecular foundations of beneficial symbiotic host-bacterial relationships in the gut are being revealed in part from studies of simplified models of this ecosystem, where germ-free mice are colonized with specified members of the microbial community, and in part from compar...
متن کاملSymbionts provide pesticide detoxification.
S ymbiosis is the intimate “living together” of different organisms (1), and symbiotic relationships range from mutually beneficial to neutral or parasitic. Indeed, many microbial–host symbioses can vary between these states, depending upon circumstances. Recent years have seen an explosion of discoveries revealing novel microbial–host relationships and interactions. In addition to “classic” nu...
متن کاملCospeciation between Hosts and Symbionts:
I. Introduction Mutualistic associations between eukaryotic hosts and their microbial partners have long been an interest of ecologists and evolutionary biologists due to the importance of understanding phylogenetic congruence, coevolution, host specificity, infectivity, and maintaining the precarious balance between pathogenicity and innocuousness. Each partner has an important function in the...
