Project description:Aquilaria yunnanensis is an endangered agarwood-producing tree currently listed on the IUCN Red List of Threatened Species. The agarwood it produces has important medicinal and economic value, but its population has sharply declined due to human destruction and habitat reduction. Therefore, obtaining genomic information on A. yunnanensis is beneficial for its protection work. We assembled a chromosome-level reference genome of A. yunnanensis by using BGI short reads, PacBio HiFi long reads, coupled with Hi-C technology. The final genome assembly of A. yunnanensis is 847.04 Mb, with N50 size of 99.68 Mb, in which 805.49 Mb of the bases were anchored on eight pseudo-chromosomes. Two gapless pseudo-chromosomes were detected in the assembly. A total of 27,955 protein-coding genes as well as 74.65% repetitive elements were annotated. These findings may provide valuable resources in conservation, functional genomics, and molecular breeding of A. yunnanensis, as well as the molecular phylogenetics and evolutionary patterns in Aquilaria.

Project description:Soybean aphid (Aphis glycines) is one of the main pests on soybeans, which causes serious damage to the soybean worldwide. The current genome of the soybean aphid is quite fragmented, which has impeded scientific research to some extent. In this study, we assembled a chromosome-level genome of the soybean aphid using MGI short reads, PacBio HiFi long reads and Hi-C reads. The genome sequence was anchored to four pseudo-chromosomes, with a total genome length of 324 Mb and a scaffold N50 length of 88.85 Mb. We evaluated the genome based on insecta_odb10 and the results show it has a completeness of 97.2%. A total of 20,781 protein-coding genes were predicted in the genome, of which 17,183 genes were annotated in at least one protein database. Our work provides a new genomic resource for the soybean aphid study.

Project description:Hydractinia symbiolongicarpus is a pioneering model organism for stem cell biology, being one of only a few animals with adult pluripotent stem cells (known as i-cells). However, the unavailability of a chromosome-level genome assembly has hindered a comprehensive understanding of global gene regulatory mechanisms underlying the function and evolution of i-cells. Here, we report the first chromosome-level genome assembly of H. symbiolongicarpus (HSymV2.0) using PacBio HiFi long-read sequencing and Hi-C scaffolding. The final assembly is 483 Mb in total length with 15 chromosomes representing 99.8% of the assembly. Repetitive sequences were found to account for 296 Mb (61%) of the total genome; we provide evidence for at least two periods of repeat expansion in the past. A total of 25,825 protein-coding genes were predicted in this assembly, which include 93.1% of the metazoan Benchmarking Universal Single-Copy Orthologs (BUSCO) gene set. 92.8% (23,971 genes) of the predicted proteins were functionally annotated. The H. symbiolongicarpus genome showed a high degree of macrosynteny conservation with the Hydra vulgaris genome. This chromosome-level genome assembly of H. symbiolongicarpus will be an invaluable resource for the research community that enhances broad biological studies on this unique model organism.

Project description:Sablefish (Anoplopoma fimbria) are in the suborder Cottioidei, which also includes stickleback and lumpfish. This species inhabits coastal regions of the northeastern and northwestern Pacific Ocean from California to Japan. A commercial fishery for sablefish began to flourish in the 1960s, though a downward trend in stock biomass and landings has been observed since 2010. Aquaculture protocols have been developed for sablefish; eggs and sperm from wild-caught and hatchery-reared captive broodstock are used to generate offspring that reach market size in about two years. Parentage analyses show that survival in aquaculture varies among families. Growth rate and disease resistance also vary among individuals and cohorts, but the extent to which genetics and the environment contribute to this variation is unclear. The sablefish genome assembly reported here will form the foundation for SNP-based surveys designed to detect genetic markers associated with survival, growth rate, and pathogen resistance. Beyond its contribution to sablefish domestication, the sablefish genome can be a resource for the management of the wild sablefish fishery. The assembly generated in this study had a length of 653 Mbp, a scaffold N50 of 26.74 Mbp, a contig N50 of 2.57 Mbp, and contained more than 98% of the 3640 Actinopterygii core genes. We placed 620.9 Mbp (95% of the total) onto 24 chromosomes using a genetic map derived from six full-sib families and Hi-C contact data.

Project description:The pink stem borer, Sesamia inferens (Walker), is a significant polyphagous pest historically restricted to regions south of N34° latitude. However, with changes in global climate and farming practices, the distribution of this moth has progressively exceeded its traditional limit of 34° N and encompassed most regions in North China. The genetic adaptations of S. inferens remain incompletely understood due to the lack of high-quality genome resources. Here, we sequenced the genome of S. inferens using PacBio and Hi-C technology, yielding a genome assembly of 865.04 Mb with contig N50 of 1.23 Mb. BUSCO analysis demonstrated this genome assembly has a high-level completeness of 96.1% gene coverage. In total, 459.72 Mb repeat sequences (53.14% of the assembled genome) and 20858 protein-coding genes were identified. We used the Hi-C technique to anchor 1135 contigs to 31 chromosomes, yielding a chromosome-level genome assembly with a scaffold N50 of 29.99 Mb. In conclusion, our high-quality genome assembly provided valuable resource that exploring the genetic characteristics of local adaptation and developing an efficient control strategy.

Project description:This study presents a chromosome-level reference genome assembly of a traditional Tibetan medicinal plant, Herpetospermum pedunculosum belonging to the Cucurbitaceae family. Following a combined PacBio high-fidelity sequencing and Hi-C analysis, a final H. pedunculosum genome assembly, 804.11 Mb in length was obtained, 90.45% of which was anchored into ten pseudochromosomes with a contig N50 of 24.39 Mb. In addition, 579.55 Mb repetitive sequences and 23,924 high-confidence protein-coding genes were annotated. Phylogenetic analysis revealed that H. pedunculosum was sister to a clade formed by cucumber, zucchini, and wax gourd. Further whole-genome duplication analysis revealed no recent polyploidization event in the H. pedunculosum genome. The high-quality H. pedunculosum genome presented here will be highly useful in investigating the molecular mechanisms underlying the biosynthesis of its active compounds and adaptation strategies to the extreme environment. It will also provide great insights into comparative genomic studies of Cucurbitaceae and flowering plants.
