Coral reefs are in rapid decline on a global scale due to human activities
and a changing climate. Shallow water reefs depend on the obligatory
symbiosis between the habitat forming coral host and its algal symbiont
from the genus Symbiodinium (zooxanthellae). This association is highly
sensitive to thermal perturbations and temperatures as little as 1°C above
the average summer maxima can cause the breakdown of this symbiosis,
termed coral bleaching. Predicting the capacity of corals to survive the
expected increase in seawater temperatures depends strongly on our
understanding of the thermal tolerance of the symbiotic algae. Here we use
molecular phylogenetic analysis of four genetic markers to describe
Symbiodinium thermophilum, sp. nov. from the Persian/Arabian Gulf, a
thermally tolerant coral symbiont. Phylogenetic inference using the
non-coding region of the chloroplast psbA gene resolves S. thermophilum as
a monophyletic lineage with large genetic distances from any other ITS2 C3
type found outside the Gulf. Through the characterisation of Symbiodinium
associations of 6 species (5 genera) of Gulf corals, we demonstrate that
S. thermophilum is the prevalent symbiont all year round in the
world's hottest sea, the southern Persian/Arabian Gulf.
Multiple sequence alignment of psba(ncr) DNA sequences from Symbiodinium
thermophilum and closely related Symbiodinium spp.This file is a multiple
sequence alignment of partial chloroplast psbA non coding region genes
from Symbiodinium thermophilum and other closely related species of
Symbiodinium. It is in a FASTA format. The first 22 Symbiodinium sequences
were obtained from algae within Porites spp. corals from the
Persian/Arabian gulf. The host identity, specific collection location and
host species for each sample are detailed in the supplementary materials
of the associated paper. The alignment was implemented using ClustalW but
heavily modified manually. Reference sequences are included in the
alignment. These are available in Genbank as detailed in the associated
paper.Dryad Submission alignment.fas
