THE ROLES OF HOST EVOLUTIONARY RELATIONSHIPS (GENUS: NASONIA) AND DEVELOPMENT IN STRUCTURING MICROBIAL COMMUNITIES
It is increasingly apparent that microbial symbionts in eukaryotes are not transient passengers randomly acquired from the environment. Rather, their varied roles in nutrition (McCutcheon et al. 2009), immunity (Lee and Mazmanian 2010), development (McFall‐Ngai 2002; Fraune and Bosch 2010), reproduction (Perlman et al. 2008; Werren et al. 2008), and speciation (Bordenstein 2003) indicate that symbiosis is a major component of eukaryotic fitness and evolution.
THE ROLES OF HOST EVOLUTIONARY RELATIONSHIPS (GENUS: NASONIA) AND DEVELOPMENT IN STRUCTURING MICROBIAL COMMUNITIES
Although decades of research have characterized the role of reproductive endosymbionts in Nasonia such as Wolbachia (Saul 1961) and Arsenophonus (Werren et al. 1986), little attention has been given to the general bacterial community in Nasonia. We report six key findings: (1) The Nasonia microbial community diversifies as development proceeds from larva to adult. (2) Microbial communities differ between host species, despite identical rearing conditions.
Speciation by symbiosis
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. We first recall Ivan Wallin's original conception from the early 20th century on the role that bacteria play in speciation.

The Woodrat Gut Microbiota as an Experimental System for Understanding Microbial Metabolism of Dietary Toxins
The microbial communities inhabiting the alimentary tracts of mammals, particularly those of herbivores, are estimated to be one of the densest microbial reservoirs on Earth. The significance of these gut microbes in influencing the physiology, ecology and evolution of their hosts is only beginning to be realized.
Insect Innate Immunity Database (IIID): An Annotation Tool for Identifying Immune Genes in Insect Genomes
The innate immune system is an ancient component of host defense. Since innate immunity pathways are well conserved throughout many eukaryotes, immune genes in model animals can be used to putatively identify homologous genes in newly sequenced genomes of non-model organisms. With the initiation of the “i5k” project, which aims to sequence 5,000 insect genomes by 2016, many novel insect genomes will soon become publicly available, yet few annotation resources are currently available for insects.
Airway bacteria drive a progressive COPD-like phenotype in mice with polymeric immunoglobulin receptor deficiency
We obtained pIgR−/− mice (C57BL/6 background)25, 26 and performed immunofluorescence microscopy to show that SIgA was not detectable on the airway surface (Fig. 1a). In addition, western blottings for secretory component from BAL fluid confirmed a lack of SIgA in the airways of pIgR−/− mice (Fig. 1b).
