Project description:The Spectacled Fulvetta (Fulvetta ruficapilla) is the type species of Fulvetta, an evolutionarily distinct group whose species show a high degree of sympatry in distribution and phenotypic convergence. To pave the way for insights into their adaptive evolution and speciation, we have assembled the first high quality reference genome for F. ruficapilla using high-fidelity (HiFi) long-read and Hi-C sequencing technologies. The resulting assembly spans a total of ~1.21 Gb with a contig N50 of 18.8 Mb and scaffold N50 of 75.9 Mb, and has a BUSCO completeness of 97.0%. The quality assessment suggests a high standard in base accuracy, continuity, and completeness of the assembly, comparable or close to that of Vertebrate Genomes Project. On this basis, we have annotated 23,774 protein-coding genes, of which 18,832 are functionally identified. The availability of this high-quality genome provides a solid foundation for the future studies of evolution and local adaptation in birds.
Project description:In this study, the complete mitochondrial genomes of Myzornis pyrrhoura and Fulvetta vinipectus were sequenced and described for the first time. The whole mitochondrial genomes of M. pyrrhoura and F. vinipectus are 17,397 bp and 16,961 bp in length, with the G + C percentage 46.34% and 47.36%, respectively. Both genomes contain 13 protein-coding genes, 22 transfer RNA genes, 2 ribosome RNA genes, and 1 non-coding control region. The arrangement of genes is identical to mitochondrial genomes of Sylviidae species reported previously. A phylogenetic reconstruction supported that M. pyrrhoura and F. vinipectus are members of family Sylviidae. The mitochondrial genomes of these two species reported here would be helpful in better understanding the phylogeny and evolution of Sylviidae.
