Dendronephthya Gigantea

Background: Coral reefs composed of stony corals are threatened by global marine environmental changes. However, soft coral communities composed of octocorallian species, appear more resilient. The genomes of several species of cnidarians have been published, including stony corals, sea anemones, and hydra, but as of yet no octocoral species. To fill this phylogenetic gap within the cnidarian, we sequenced the octocoral, Dendronephthya gigantea, a non-symbiotic soft coral, commonly known as the carnation coral. Findings: The D. gigantea genome size is approximately 276 Mb. A high-quality genome assembly was constructed using 29.85Gb (108x coverage) of PacBio long reads and 35.54Gb (128x coverage) of Illumina short paired-end reads resulting in the largest N50 value reported among cnidarian of 1.4 Mb. About 12 % of the genome consisted of repetitive elements. We found 28,879 protein-coding genes. This gene set contained about 94% metazoan single-copy orthologs, indicating the gene models were predicted with high quality compared to other cnidarians. Based on molecular phylogenetic analysis, octocoral and hexacoral divergence occurred approximately 544 million years ago. Moreover, there is a clear difference in Hox gene composition: unlike in hexacorals, Antp superclass member Evx gene was absent in D. gigantea. Conclusions: We present the first genome assembly of a non-symbiotic octocoral, D. gigantea to aid in the comparative genomic analysis of cnidarians, including comparisons of stony and soft corals and symbiotic and non-symbiotic corals. In addition, the genome of this species may provide clues about differential genetic coping mechanisms between soft and stony coral regarding the global warming.

Microbacterium mangrovi strain MUSC 115T was isolated from intertidal sediments of Kuantan, Malaysia. Here we describe the draft genome of amylolytic strain MUSC 115T with total size of 4.4 Mbp from 55 contigs and G + C content of 70.0%. Total of 4,096 coding genes were observed, with 2 putative amylases genes in the draft genome of MUSC 115T. These genome features of MUSC 115T can improve our understanding of its starch-degrading mechanism and general physiology of the species, which provide opportunities for biotechnological and industrial exploitation.

Here, we report 12 draft genome sequences of mutant Mycolicibacterium smegmatis strains resistant to imidazo[1,2-b][1,2,4,5]tetrazines, which are antituberculosis drug candidates. We have identified 7 different mutations in the MSMEG_1380 gene, which encodes the AcrR/TetR_N transcriptional repressor, which may activate efflux-mediated resistance.
