Haplotype-resolved genome assembly of the tetraploid Youcha tree Camellia meiocarpa Hu.
Camellia meiocarpa Hu, a member of Youcha species in the genus Camellia, is an important woody edible Youcha plant with high ecological and economic value. The haplotype-resolved genome assembly of this tetraploid species can shed light on genomic evolution and the functional divergence among subgenomes and haplotypes. In this study, we achieved the first chromosome-level haplotype-resolved genome assembly using PacBio HiFi, Hi-C, and Illumina sequencing. The scaffolds, with an N50 of 44.46 Mb and 41.40 Mb, were mapped to 60 chromosomes and four distinct haplotypes, each with unique transposon features. The haplotypes varied in length (2967.25 Mb to 3041.66 Mb) and contained 51,336 to 52,631 protein-coding genes, 99.4% of which were annotated. Non-coding RNAs and repetitive elements were identified across haplotypes. This comprehensive genomic resource will enhance molecular and genetic studies, aiding in the conservation and utilization of Youcha.
期刊介绍：
Scientific Data is an open-access journal focused on data, publishing descriptions of research datasets and articles on data sharing across natural sciences, medicine, engineering, and social sciences. Its goal is to enhance the sharing and reuse of scientific data, encourage broader data sharing, and acknowledge those who share their data.
The journal primarily publishes Data Descriptors, which offer detailed descriptions of research datasets, including data collection methods and technical analyses validating data quality. These descriptors aim to facilitate data reuse rather than testing hypotheses or presenting new interpretations, methods, or in-depth analyses.
