dc.description.abstract | As seawater temperature rises, repeated thermal bleaching events have negatively
affected the reefs of the Andaman Sea for over decades. Studies on the coralassociated microbial diversity of prokaryotes and microbial eukaryotes (microbiome) in
healthy and bleached corals are important to better understand the coral holobionts
that involved augmented resistance to stresses, and this information remains limited in
the Andaman Sea of Thailand. The present study thereby described the microbiomes
of healthy (unbleached) and bleached colonies of four prevalent corals, Acropora
humilis, Platygyra sp., Pocillopora damicornis, and Porites lutea, along with the
surrounding seawater and sediments, that were collected during a 2016 thermal
bleaching event, using 16S and 18S rRNA genes next-generation sequencing (NGS).
Both prokaryotic and eukaryotic microbes showed isolated community profiles among
sample types (corals, sediment, and seawater) [analysis of similarities (ANOSIM):
p = 0.038 for prokaryotes, p < 0.001 for microbial eukaryotes] and among coral
genera (ANOSIM: p < 0.001 for prokaryotes and microbial eukaryotes). In bleached
state corals, we found differences in microbial compositions from the healthy state
corals. Prevalent differences shared among bleached coral genera (shared in at least
three coral genera) included a loss of reported coral-beneficial microbes, such as
Pseudomonadales, Alteromonadales, and Symbiodinium; meanwhile an increase of
putative coral-pathogenic Malassezia and Aspergillus. This difference could affect
carbon and nitrogen availability for coral growth, reflective of a healthy or bleached
state. Our findings in part supported previously microbial dysbiosis knowledge of thermal
bleaching coral microbiomes around South East Asia marine geography, and together
ongoing efforts are to support the understanding and management of microbial diversity
to reduce the negative impacts to corals in massive thermal bleaching events. | en_US |
