The Xishuangbanna game fowl, a local Chinese chicken breed renowned for its athleticism, is facing extinction. Despite its significance, research on its genome assembly and resequencing remains sparse, limiting our understanding of its genetic structure and function. In this study, we assembled a chromosome-level genome using second-generation sequencing and high-throughput chromosome conformation capture (Hi-C), along with transcriptome sequencing.

In this study, we employed an orthogonal experimental design (T1-T9) with three fertilization treatments (N, P, and K) at three levels to identify an optimal fertilization scheme for strawberry cultivation. The effects of fertilizer combinations the rhizosphere soil microbial community were also explored by using bacterial full-length 16S rRNA and fungal ITS (internal transcribed spacer) sequencing (30 samples for each analysis).

Results: The study identified 16 haplogroups with fine-scale phylogenetic resolution using mitochondrial genomes of 317 horse samples. The time to the most recent common ancestor of the 16 haplogroups ranges from [0.
The fish genus Sinocyclocheilus contains many different species that inhabit diverse natural environments, such as surface water layer, cave, or intermediate. As a result of these different habitats there are some differences in their sensory systems. Microscopic and submicroscopic structures of olfactory systems in six representative species of Sinocyclocheilus were studied, including one surface-dwelling species (S.

Recently, there were more and more transcriptomes of leech published online including the medicinal leech (Hirudo medicinalis) and some other leeches. However, leech's genetic backgrounds are still largely unknown.

In this study, we first determined the complete mitochondrial genome sequence of , which is an endemic species to Southwestern China. The complete mitochondrial genome is 16,577 bp in length, consisting of 37 genes coding for 13 proteins, two rRNAs, 22 tRNAs, and one control region. Its gene arrangement pattern was identical to that of most vertebrates.

Despite the economic importance of this insect-disease complex, only a few studies are available on the population genetic structure of M. alternatus and the relationship between its historic dispersal pattern and various human activities.
View Article and Find Full Text PDFAttempts to understand the degeneration of the eyes in cave fish has largely been explained by either various extents of gradual degeneration, ranging from partial to total loss, observed in various species or by acceleration of loss caused by dark environments. However, neither the theory of biological evolution developed by Charles Darwin nor the neutral theory of molecular evolution formulated by Kimura Motoo adequately explains these phenomena. Recent trends in utilizing multidisciplinary research, however, have yielded better results, helping reveal a more complex picture of the mechanisms of degeneration.
