Abstract

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.

摘要

Mahachai bettas（Betta mahachaiensis）分布在泰国Samut Sakhon的咸水和Nipa Palms地区，但城市化限制了它们的生物多样性。一个完整的线粒体基因组（线粒体基因）B. mahachaiensis被确定为支持环保项目。线粒体基因组序列长16,980 bp，带有轻微的AT偏倚（61.91％），包含37个基因，其顺序与大多数硬骨鱼有丝分裂基因组相同。系统发育分析B. mahachaiensis显示有密切的关系B.芨芨草。结果将允许创建一个参考注释的基因组，该基因组可用于维持斗鱼的生物多样性和生态管理以改善保护计划。
