“…Most attention to date has focused on fishes and stony corals (Figure 5), mirroring their ecological and economic importance as fishery targets and foundation species. The ability to bring long-read DNA sequencers to the field provides a novel opportunity to rapidly expand the availability of genomic resources for coral reef taxa (27,39) by expediting sequencing timelines, involving local scientists, and simplifying permit logistics.…”

Coral reefs are both exceptionally biodiverse and threatened by climate change and other human activities. Here, we review population genomic processes in coral reef taxa and their importance for understanding responses to global change. Many taxa on coral reefs are characterized by weak genetic drift, extensive gene flow, and strong selection from complex biotic and abiotic environments, which together present a fascinating test of microevolutionary theory. Selection, gene flow, and hybridization have played and will continue to play an important role in the adaptation or extinction of coral reef taxa in the face of rapid environmental change, but research remains exceptionally limited compared to the urgent needs. Critical areas for future investigation include understanding evolutionary potential and the mechanisms of local adaptation, developing historical baselines, and building greater research capacity in the countries where most reef diversity is concentrated. Expected final online publication date for the Annual Review of Genetics, Volume 57 is November 2023. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…In this study, the complete mitochondrial genome of H. bowerbanki was sequenced and assembled for the first time through a next-generation sequencing method (NGS), in which its genome structure and nucleotide composition were characterized and analysed. Phylogenetic analyses of H. bowerbanki , based on 13 protein-coding genes (PCGs) of the mitogenome, will help determine its taxonomic classification and facilitate ongoing taxonomic revisions of scleractinian taxa [ 12 ]; analyses can also clarify the evolutionary and phylogenetic relationships amongst stony corals in favor of coral species monitoring and conservation efforts [ 13 ].…”

Reef-building coral species of the order Scleractinia play an important role in shallow tropical seas by providing an environmental base for the ecosystem. The molecular data of complete mitochondrial genome have become an important source for evaluating phylogenetic and evolutionary studies of Scleractinia. Here, the complete mitogenome of Homophyllia bowerbanki (Milne Edwards and Haime, 1857), collected from Nansha Islands of the South China Sea, was sequenced for the first time through a next-generation sequencing method. H. bowerbanki is the first species of its genus for which the mitogenome was sequenced. This mitogenome was 18,154 bp in size and included two transfer RNA genes (tRNAs), 13 protein-coding genes (PCGs), and two ribosomal RNA genes (rRNAs). It showed a similar gene structure and gene order to the other typical scleractinians. All 17 genes were encoded on the H strand and the total GC content was 33.86% in mitogenome. Phylogenetic analysis (maximum likelihood tree method) showed that H. bowerbanki belonged to the “Robust” clade and clustered together with other two species in the family Lobophylliidae based on 13 PCGs. The mitogenome can provide significant molecular information to clarify the evolutionary and phylogenetic relationships between stony corals and to facilitate their taxonomic classification; it can also support coral species monitoring and conservation efforts.

“…The phylogenetic position of M. vietnamensis within the family Acroporidae , based on protein coding genes of the mitogenome, will help determine its taxonomic status and facilitate further study on stony coral evolutionary and phylogenetic relationships ( Tian et al 2022 ). Ultimately, this information can aid in species monitoring and conservation efforts ( Colin et al 2021 ).…”

Montipora vietnamensis Veron, 2000 (Cnidaria, Anthozoa, Scleractinia, Acroporidae) is an uncommon, but distinctive species of stony coral. The complete mitochondrial genome of M. vietnamensis was sequenced in this study for the first time, based on 32 pairs of primers newly designed according to seven species in the family Acroporidae. The mitogenome of M. vietnamensis has a circular form and is 17,885 bp long, including 13 protein-coding genes (PCGs), 2 tRNA (tRNAMet, tRNATrp), 2 rRNA genes and a putative control-region. The base composition of the complete mitogenome was 24.8% A, 14.2% C, 24.2% G and 36.8% T, with a higher AT content (61.6%) than GC content (38.4%). Based on 13 protein-coding genes, a Maximum Likelihood phylogenetic analysis showed that M. vietnamensis is clustered in the genus Montipora which belongs to the family Acroporidae. More stony coral species should be sequenced for basic molecular information and to help confirm the taxonomic status and evolutionary relationships of Scleractinia in the future.
