We reported the mitochondrial genome (mitogenome) of bronze-winged jacana ( Metopidius indicus , Latham 1790). The circular mitogenome was 17,208 base pairs (bp) in length, containing 13 protein-coding genes, two rRNAs, 22 tRNAs, and a non-coding control region. A DNA spacer 109 bp long was also detected between ND5 and Cytb . Phylogenetic analysis indicated that M. indicus was more closely related with the genera Himantopus , Jacana and Hydrophasianus . This annotated mitogenome reference can be utilized as a data resource for comparative mitogenomics of waders or shorebirds, with possible use in ecological and evolutionary studies., Competing Interests: The authors report no conflicts of interest and are entirely responsible for the contents of this article., (© 2021 The Author(s).

Mekong fighting fish ( Betta smaragdina ) are found in Northeast Thailand. A complete mitochondrial genome (mitogenome) of B. smaragdina was assembled and annotated. Mitogenome sequences were 16,372 bp in length, with slight AT bias (59.8%), containing 37 genes with identical order to most teleost mitogenomes. Phylogenetic analysis of B. smaragdina showed closer relationship with B. splendens and B. mahachaiensis as the bubble-nesting group, compared to the mouthbrooder group ( B. apollon , B. simplex , and B. pi ). Results will allow the creation of a reference annotated genome that can be utilized to sustain biodiversity and eco-management of betta bioresources to improve conservation programs., Competing Interests: The authors report no conflicts of interest and are entirely responsible for the contents of this article. Animal care and all experimental procedures were approved by the Animal Experiment Committee, Kasetsart University, Thailand (approval no. ACKU63-SCI-007) and conducted in accordance with the Regulations on Animal Experiments at Kasetsart University., (© 2021 The Author(s).

The complete mitochondrial genome (mitogenome) of the peaceful betta ( Betta imbellis ) was obtained using next-generation sequencing. The sample of B. imbellis was collected from its native habitat in Southern Thailand. The mitogenome sequence was 16,897 bp in length, containing 37 genes with identical order to most teleost mitogenomes. Overall nucleotide base composition of the complete mitogenome was determined as AT bias. Phylogenetic analysis of B. imbellis showed a closer relationship with bubble-nesting fighting fish. This annotated mitogenome reference can be utilized as a bioresource for phylogenetic studies to support betta conservation programs., Competing Interests: The authors report no conflicts of interest and are entirely responsible for the contents of this article.

Mahachai bettas ( Betta mahachaiensis ) are distributed in areas of brackish water with Nipa Palms in Samut Sakhon, Thailand but urbanization is restricting their biodiversity. A complete mitochondrial genome (mitogenome) of B. mahachaiensis was determined to support conservation programs. Mitogenome sequences were 16,980 bp in length with slight AT bias (61.91%), containing 37 genes with identical order to most teleost mitogenomes. Phylogenetic analysis of B. mahachaiensis showed a closer relationship with B. splendens . Results will allow the creation of a reference annotated genome that can be utilized to sustain biodiversity and eco-management of the betta to improve conservation programs., Competing Interests: The authors report no conflicts of interest and are entirely responsible for the contents of this article.
