SUMMARY;LANGUAGE=en-us:Jillian Petersen: How environments shape microbiome 
 innovations in the natural world
DESCRIPTION:Planetary Biology Lectures\nSpeaker: Jillian Petersen\nInstitut
 ion: Centre for Microbiology and Environmental Systems Science\nUniversity 
 of Vienna\, Austria\nHost: Detlev Arendt\, Peer Bork\, Rainer Pepperkok\nA
 bstract: Virtually every living organism\, including humans\, relies on sy
 mbiotic microbial partners that provide a range of health benefits includi
 ng synthesizing food and vitamins\, protecting against pathogens\, and det
 oxifying the environment. These symbiotic partnerships evolved in a comple
 x environmental context\, but our understanding of how the environment dri
 ves the function and evolution of host-microbe interactions is still in it
 s infancy. In the marine environment\, ‘extreme’ or challenging habitats a
 re characterized by symbioses between animals and the microbes that underp
 in their survival. One ubiquitous example is lucinid clams\, which burrow 
 in sandy coastal sediments\, a challenging habitat for animals due to the 
 complete lack of oxygen\, and abundance of the toxin sulfide. However\, th
 ey have teamed up with bacterial symbionts that use this toxic sulfide to 
 power primary production\, turning toxins into food for their hosts. These 
 partnerships are so successful\, the animal hosts have diversified into on
 e of the most species-rich animal families in the oceans today\, and have 
 dispersed to a range of coastal and deep-sea habitats worldwide. Thanks to 
 their reliance on environmental energy sources\, and the natural ‘simplici
 ty’ of this symbiosis between one host and one prominent bacterial symbion
 t species\, they are ideal for understanding how environments shape microb
 iomes at the molecular level. I will outline the genomic innovations that 
 underpin the ecological and evolutionary success of these symbioses from s
 eagrass meadows to the deep sea.\nStream link: https://embl-de.zoom.us/j/9
