Article Abstract
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.

Background: In horses, genetic diversity is predominantly observed between breeds, with little variation within breeds. The studbooks of the two largest horse populations in the Netherlands, the Dutch Warmblood horse and Friesian horse population, have ongoing conservation projects including collecting large-scale genotype and sequence data. The current reference genome, derived from a Thoroughbred horse can lead to bias in genetic analyses of other horse breeds.

Spinibarbus caldwelli is a cyprinid freshwater fish of significant economic and ecological value that is known for its strong environmental adaptability and disease resistance. As an allotetraploid species with a complex genome structure, the lack of a high-quality reference genome has long hindered in-depth studies on its evolutionary mechanisms and adaptive basis. In this study, we employed PacBio HiFi long-read sequencing in combination with Hi-C technology to generate a high-quality, haplotype-resolved chromosome-level reference genome of S.
