In addition I would like to see some research focusing on the vibrio species from the paper by Garran et al. that we reviewed today, and how it utilises the chemical gradient, I wonder if it is something controlled by a particular gene and if so does the fact that the vibrio species does not appear to metabolise DMSP indicate that such a gene could have been acquired fairly recently?Lucyhttps://www.blogger.com/profile/17886020450017463934noreply@blogger.comtag:blogger.com,1999:blog-8441491750914005356.post-85738046653470334702013-11-19T19:20:20.105+00:002013-11-19T19:20:20.105+00:00In the seminar today we reviewed the paper by Garr...In the seminar today we reviewed the paper by Garren et al. which showed that a vibrio species exhibited chemotaxis and chemokinesis in response to DMSP allowing it to infect the coral which in turn would cause bleaching. This made me think about the way in which corals acquire their symbionts initially; could the production of DMSP by corals be used as a chemical gradient by the symbiotic algae as well as by the vibrio species? or could it also help the coral reacquire a more temperature tolerant symbiont following bleaching? could the genes have been transferred from one bacterial species to another by a virus maybe? I think i came out of the seminar with more questions than were answered!

It would be interesting to look at gene expression under differing conditions certainly.Lucyhttps://www.blogger.com/profile/17886020450017463934noreply@blogger.comtag:blogger.com,1999:blog-8441491750914005356.post-39093383760095024582013-11-19T17:03:26.953+00:002013-11-19T17:03:26.953+00:00It is an appealing idea that the DMSP production c...It is an appealing idea that the DMSP production could cool the SST due to cloud formation and albedo effect over coral reefs, as predicted by the CLAW hypothesis. It's worth noting that new evidence has led some authors to dispute the importance of DMS in regulating global climate - check out this review by Quinn & BAtees, 2011 http://www.nature.com/nature/journal/v480/n7375/full/nature10580.html. However, there could still be a strong case to say that it might operate on a more local level (e.g. above a major reef system like the GBR). Are coral animals unique in evolving DMSP production because they been especially sensitive to major climatic change in the past? It will be fascinating to see if DMSP related genes are present in other Cnidaria or in other marine inverts.Colin Munnhttps://www.blogger.com/profile/09574545828249747262noreply@blogger.comtag:blogger.com,1999:blog-8441491750914005356.post-21498365009848555452013-11-19T16:28:59.072+00:002013-11-19T16:28:59.072+00:00That's a really interesting post Lucy.

Raina et al, 2010, suggest that DMSP/DMS plays a role in structuring the bacterial community associated with reef coral, which is important for the coral health and resilience. Maybe this could explain why the corals appear to maintain a certain level of DMSP?Anonymoushttps://www.blogger.com/profile/05400426162718169047noreply@blogger.comtag:blogger.com,1999:blog-8441491750914005356.post-82734343085300266702013-11-15T10:14:46.747+00:002013-11-15T10:14:46.747+00:00So do you think they are producing DMSP in place o...So do you think they are producing DMSP in place of the symbiont or as well as? Could you test to see if the DMSP related genes are still expressed as much when symbionts are present?Anonymoushttps://www.blogger.com/profile/08280730274629709918noreply@blogger.com
