Abstract
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.
Highlights
The complete mitochondrial genome of the peaceful betta (Betta imbellis) was obtained using next-generation sequencing
Southeast Asia (SEA) is a well-known biocultural hotspot of biodiversity and endemism encompassing a huge variety of betta fish (Betta spp.) belonging to the family Osphronemidae (Panijpan et al 2014)
A complete mitochondrial genome of B. imbellis collected from Nakhon Si Thammarat, Thailand (8.4325 N, 99.9599 E), was assembled, annotated, analyzed, and stored in the Thailand Natural History Museum
