Bacterial Endosymbionts and Insect Hosts Practice “Supply-Side” Metabolism
Endosymbiotic bacteria within some insects supply their hosts with essential nutrients that enable those hosts to live in specialized environmental niches. In particular, blood-feeders such as bedbugs and tsetse flies, and plant-sap feeders such as pea aphids, citrus mealybugs, and cicadas rely heavily on their microbial symbiotic partners for B vitamins and amino acids that are otherwise lacki...
متن کاملObligate symbiont involved in pest status of host insect.
The origin of specific insect genotypes that enable efficient use of agricultural plants is an important subject not only in applied fields like pest control and management but also in basic disciplines like evolutionary biology. Conventionally, it has been presupposed that such pest-related ecological traits are attributed to genes encoded in the insect genomes. Here, however, we report that p...
متن کاملBacterial endosymbionts in animals.
Molecular phylogenetic studies reveal that many endosymbioses between bacteria and invertebrate hosts result from ancient infections followed by strict vertical transmission within host lineages. Endosymbionts display a distinctive constellation of genetic properties including AT-biased base composition, accelerated sequence evolution, and, at least sometimes, small genome size; these features ...
متن کاملThe Role of Yeasts as Insect Endosymbionts
Insect associations with fungi are common and may be casual or highly specific and obligate. For example, more than 40 fungal species are associated with the coffee berry borer (Hypothenemus hampei, Coleoptera: Curculionidae; Pérez et al. 2003) and about the same number with the subterranean termite Reticulitermes flavipes (Zoberi and Grace 1990; table 9.1). In one system 28 species of yeasts w...
متن کاملHijacking Host Cell Highways: Manipulation of the Host Actin Cytoskeleton by Obligate Intracellular Bacterial Pathogens
Intracellular bacterial pathogens replicate within eukaryotic cells and display unique adaptations that support key infection events including invasion, replication, immune evasion, and dissemination. From invasion to dissemination, all stages of the intracellular bacterial life cycle share the same three-dimensional cytosolic space containing the host cytoskeleton. For successful infection and...
