introduction led to a substantial reduction in ecosystem productivity. Intriguingly, the host regulatory pathways that control immune responses to microbes appear also to have central roles in animal development, underscoring the intimate relationships between development and hostmicrobe interactions ( 58, 59 ). This review examines how a growing knowledge of the vast range of animalbacterial interactions, whether in shared ecosystems or intimate symbioses, is fundamentally altering our understanding of animal biology. I can call my preferred writer my friend, literally. However, in one case, the association with a Wolbachia strain has become essential for reproduction; the wasp Asobara tabida requires this microbe for egg maturation ( 63 ).

Whereas developmentally important symbioses have been documented throughout the postembryonic (larval and juvenile) stages of vertebrate and arthropod life cycles, the roles of symbiotic microbes during normal embryonic development are just beginning to be studied. Thus, the discovery that at least one choanoflagellate, Salpingoeca rosetta, responds to signals from specific bacteria to initiate colony formation through cell division hints at an ancient apa how to cite a dissertation 6th edition involvement of bacteria in the initiation of multicellularity ( 9 ). Although many animals, including a wide variety of insects, have transovarial (i.e., via the egg to the embryo) transmission of bacterial partners ( 28, 45 we have no persuasive evidence to date that these microbes or their metabolites influence embryogenesis.

Recent studies demonstrate that the larvae of many benthic marine invertebrates require specific microbial cues for their recruitment from the plankton, and these larval responses to bacteria influence the structuring of many marine benthic communities ( 60, 107 ). Ample evidence shows that microbes act directly as agents of postembryonic development. Nonetheless, the underlying ecological mechanisms are still poorly defined, and the development of tools to translate this understanding into novel therapies presents an ongoing challenge.

Unlike vertebrates whose embryos develop human brain research paper inside enclosures that physically block bacterial associations, many invertebrates acquire their symbionts through the female germ line.

Not surprisingly, many animal genes are homologs of bacterial genes, mostly derived by descent, but occasionally by gene transfer from bacteria ( 21 ). The reciprocal may also be true,.e., an animals microbial partners may have played a role in selecting for the trait of endothermy.
