Hi CDHC List Members:
A fellow CDHC Member asked that I let the rest of you know about a new
publication from their group. Please contact the authors directly if
you are interested in reprints.

Microbial functional structure of Montastraea faveolata, an important
Caribbean reef-building coral, differs between healthy and yellow-band
diseased colonies.

A functional gene array (FGA), GeoChip 2.0, was used to assess the
biogeochemical cycling potential of microbial communities associated
with healthy and Caribbean yellow band diseased (YBD) Montastraea
faveolata. Over 6700 genes were detected, providing evidence that the
coral microbiome contains a diverse community of archaea, bacteria and
fungi capable of fulfilling numerous functional niches. These included
carbon, nitrogen and sulfur cycling, metal homeostasis and resistance,
and xenobiotic contaminant degradation. A significant difference in
functional structure was found between healthy and YBD M. faveolata
colonies and those differences were specific to the physical niche
examined. In the surface mucopolysaccharide layer (SML), only two of 31
functional categories investigated, cellulose degradation and
nitrification, revealed significant differences, implying a very
specific change in microbial functional potential. Coral tissue slurry,
on the other hand, revealed significant changes in 10 of the 31
categories, suggesting a more generalized shift in functional potential
involving various aspects of nutrient cycling, metal transformations and
contaminant degradation. This study is the first broad screening of
functional genes in coral-associated microbial communities and provides
insights regarding their biogeochemical cycling capacity in healthy and
diseased states.
