“…The negative AT skew value was inconsistent with that for most mammalians, which had positive AT skew values ( Sarvani et al 2018 ; Priyono et al 2020 ). However, the result of the current study is highly similar to the result obtained for Camelus dromedarius (both AT and GC skews were negative), a heat-tolerant mammal ( Sarvani et al 2018 ; Manee et al 2019 ).…”

“…The ATP6, ATP8, ND2, and ND3 genes had positive AT skews, whereas the remaining genes (9 of 13) had negative values. Notably, ND6 had deviation ranges for AT skew (–0.303) and GC skew (0.636) when compared with the other 12 PCGs in the L. yarkandensis mtDNA sequence, and the deviation range is highly similar to some mammalians, such as Moschiola indica , Camelus dromedarius , and Bubalus quarlesi ( Sarvani et al 2018 ; Manee et al 2019 ; Priyono et al 2020 ).…”

Lepus yarkandensis is a national second-class protected animal endemic to China and distributed only in the hot and arid Tarim Basin in Xinjiang. We sequenced and described the complete mitogenome of L. yarkandensis to analyze its characteristics and phylogeny. The species’ DNA is a 17,047 bp circular molecule that includes 13 protein-coding genes (PCGs), two rRNA genes, 22 tRNA genes, and one control region. The overall base composition was as follows: A, 31.50%; T, 29.40%; G, 13.30% and C, 25.80%, with a high A+T bias of 60.9%. In the PCGs, ND6 had deviation ranges for AT skew (–0.303) and GC skew (0.636). The Ka/Ks values of ND1 (1.067) and ND6 (1.352) genes were >1, indicating positive selection, which might play an important role in the adaptation of L. yarkandensis to arid and hot environments. The conserved sequence block, the central conserved domain, and the extended termination-associated sequences of the control region and their features were identiﬁed and described. The phylogenetic tree based on the complete mitogenome showed that L. yarkandensis was closely related to the sympatric Lepus tibetanus pamirensis. These novel datasets of L. yarkandensis can supply basic data for phylogenetic studies of Lepus spp., apart from providing essential and important resource for further genetic research and the protection of this species.

the gaur is the largest extant cattle species and distributed across South and Southeast Asia. Around 85% of its current global population resides in India, however there has been a gradual decrease in the gaur population over the last two decades due to various anthropogenic activities. Mitochondrial genome is considered as an important tool for species identification and monitoring the populations of conservation concern and therefore it becomes an obligation to sequence the mitochondrial genome of Indian gaur. We report here for the first time 16,345 bp mitochondrial genome of four Indian gaur sequenced using two different approaches. Mitochondrial genome consisted of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. Among the 37 genes, 28 were positioned on the H-strand and 9 were positioned on the L-strand. The overall base composition appeared to be 33.5% A, 27.2% T, 25.9% C and 13.4% G, which yielded a higher AT content. The phylogenetic analysis using complete mitochondrial genome sequences unambiguously suggested that gaur is the maternal ancestor of domestic mithun. Moreover, it also clearly distinguished the three sub species of B. gaurus i.e. B. gaurus gaurus, B. gaurus readei and B. gaurus hubbacki. Among the three sub species, B. gaurus gaurus was genetically closer to B. gaurus readei as compared to B. gaurus hubbacki. The findings of our study provide an insight into the genetic structure and evolutionary history of indian gaur. The gaur, Bos gaurus also known as "Indian bison" is the largest living wild cattle species belonging to the family Bovidae 1. The historical distribution of gaur ranged throughout much of the mainland South and Southeast Asia. But, currently it occurs in a few Asian countries such as Bangladesh,

The Gayal is a large-sized endangered semi-domesticated bovine species belonging to the family Bovidae, tribe Bovini, group Bovina, genus Bos, and species Bos frontalis. It is also called the Mithan or Mithun. Mitochondrial genome is considered as an important tool for species identification and monitoring the populations of conservation concern and therefore it becomes an obligation to sequence the mitochondrial genome of Bagladeshi gayal. We want to identify some important genes related to a particular trait such as those associated with adaptation, muscle strength, or prolificacy. The data will help explore evolutionary relationships with closely related species. The mitogenome of Bos frontalis is 16,347 bp in length and nucleotide composition is AT-based (60.21%), contains 37 genes including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region.
