Abstract

Nicobari pig and Andaman Desi pig are indigenous pig germplasm of Andaman and Nicobar islands, India. Over the last two decades, the pig breeds witnessed a rapid decline in population, necessitating immediate characterization and conservation. The present study depicts the complete mitochondrial genome sequence of Nicobari pig and Andaman Desi pig. The mitogenomes of both the breeds encode 37 genes including 13 protein coding genes, 22 tRNAs, and two ribosomal RNA genes. In addition, a control region (D-loop) was also present. Phylogenetic analysis showed that Nicobari is phylogenetically close to Banna mini and Breed I pig, whereas Andaman Desi pig is close to Mong cai and Jinhua pig breeds. The results of the study will be helpful for formulating of conservation strategy of the native swine breeds.

摘要

尼科巴猪和安达曼德西猪是印度安达曼和尼科巴群岛的本土猪种资源。在过去二十年里，这两个猪种的数量急剧下降，因此有必要立即对其进行特性描述和保护。本研究描绘了尼科巴猪和安达曼德西猪完整的线粒体基因组序列。这两个猪种的线粒体基因组都编码37个基因，包括13个蛋白质编码基因、22个tRNA和两个核糖体RNA基因。此外，还存在一个控制区（D环）。系统发育分析表明，尼科巴猪在系统发育上与版纳微型猪和品种I猪相近，而安达曼德西猪则与蒙古猪和金华猪品种相近。该研究结果将有助于制定本土猪种的保护策略。
