Its outer umbrella surface is covered with white spots and it is mainly distributed in the Pacific and Indian Ocean. In this study, we generated a haplotype-resolved, chromosome-scale genome assembly for M. papua using PacBio HiFi long reads and Hi-C technology. The resulting assembly contains two haplotypes (Hap A and Hap B) with sizes of 379.81 MB (contig N50 = 13.03 Mb) and 344.57 MB (contig N50 = 14.24 Mb), and both anchored to 21 chromosomes with anchor ratio of 94.35% and 97.59%, respectively. The sequencing depth, mapping coverage, contig continuity, and BUSCO assessment collectively indicate a high-quality haplotype-resolved genome assembly. This high-quality genome assembly provides a valuable resource for further genetic studies and genetic improvement of the group of M. papua. BUSCO assessment indicated that the completeness of the two haploid genomes was 93.3% (HapA) and 92.2% (HapB), respectively, demonstrating excellent assembly quality. Annotation results identified 27,401 protein-coding genes and 182.83 Mb of repetitive sequences (accounting for 48.14% of the genome) in HapA, while HapB contained 23,905 protein-coding genes and 158.00 Mb of repetitive sequences (representing 45.85% of the genome). Functional annotation revealed that over 88% of the genes could be matched to public databases such as NR, KEGG, and GO. These phased genome assemblies and gene annotations provide a quality-controlled genomic resource for Mastigias papua.","PeriodicalId":21597,"journal":{"name":"Scientific Data","volume":"13 1","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13518791/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148832134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They underpin key biological analyses such as gene and transcript quantification, and the study of transcriptional and post-transcriptional regulation, including alternative transcription initiation, polyadenylation and splicing. Accurate characterisation of transcript isoforms is critical for understanding how gene expression relates to functional protein products. However, for many species-including Solanaceae crops such as potato and tomato-current annotations suffer from limited isoform coverage, with tens or hundreds of thousands of splice junctions and transcript isoforms missing. This undermines the completeness and accuracy of transcript-level analyses. Here, by generating Iso-seq and RNA-seq on a range of tissues and samples, we have produced transcriptome annotations for both potato and tomato with improved coverage, diversity, accurate splice junctions, and transcript start and end sites. We have also made these high-quality resources accessible through genome browsers.

To better understand human pathologies, relevant models and methodologies must be made available. In this study, we focused on a biomedical model capable of recapitulating the complexity of human pathology, the pig (Sus scrofa). Brain tissue and cerebrospinal fluid samples from a transgenic minipig model of Huntington's disease were subjected to multiple extraction and fractionation steps. A proteomic mass spectrometry (MS) methodology then allowed the generation of a porcine spectral library for 8,321 proteins. Using data-independent acquisition (DIA), we demonstrated that our porcine spectral library substantially enhanced the quantitative potential of this untargeted MS approach, generating reproducible proteome-wide data.
