Understanding the evolutionary processes that have created diversity and
the genetic potential of species to adapt to environmental change is an
important premise for biodiversity conservation. Herein, we used
mitochondrial trnW-L and cox3 and plastid rbcL-S data sets to analyze
population genetic variation and phylogeographic history of the brown alga
Sargassum fusiforme, whose natural resource has been largely exterminated
in the Asia-Northwest Pacific in the past decades. Phylogenetic trees and
network analysis consistently revealed three major haplotype-groups (A, B
and C) in S. fusiforme, with A and B distributed in the Japan-Pacific
coast. Group C consisted of three sub-groups (C1, C2 and C3) which were
distributed in the Sea of Japan, the Yellow-Bohai Sea and East China Sea,
respectively. Isolation-with-migration (IMa) analysis revealed that the
three groups diverged approximately during the mid-Pleistocene (c.
756–1,224 ka). Extended Bayesian skyline plots (EBSP) showed that groups A
and B underwent relatively long-term stable population size despite a
subsequent rapid demographic expansion, while sub-groups C2 and C3
underwent a sudden expansion at c. 260 ka. FST and AMOVA analysis detected
low population-level genetic variation and high degrees of divergence
between groups. The cryptic diversity and phylogeographic patterns found
in S. fusiforme not only are essential to understand how environmental
shifts and evolutionary processes shaped diversity and distribution of
coastal seaweeds but also provide additional insights for conserving and
managing seaweed resources and facilitate predictions of their responses
to future climate change and habitat loss.
Detailed sampling information and DNA sequences for genetic analysesThere
are three files in the compressed file folder.One Excel file has listed
detailed sampling information for each population of Sargassum fusiforme.
The second file in fasta format consists of the concatenated sequences of
560 mitochondrial trnW-L spacer and cox3 gene. The last file in fasta
format includes 592 sequences of chloroplast rbcL-S spacer.MEC-16-0703.zip
