Cultivar Désirée is an important model for potato functional genomics studies to assist breeding strategies. Here, we present a haplotype-resolved genome assembly of Désirée, achieved by assembling PacBio HiFi reads and Hi-C scaffolding, resulting in a high-contiguity chromosome-level assembly. We implemented a comprehensive annotation pipeline incorporating gene models and functional annotations from the Solanum tuberosum Phureja DM reference genome alongside RNA-seq reads to provide high-quality gene and transcript annotations. Additionally, we provide a genome-wide DNA methylation profile using Oxford Nanopore reads, enabling insights into potato epigenetics. The assembled genome, annotations, methylation and expression data are visualised in a publicly accessible genome browser, providing a valuable resource for the potato research community.
“德西蕾”品种是马铃薯功能基因组学研究以辅助育种策略的重要模型。在此,我们展示了“德西蕾”的单倍型解析基因组组装,通过组装PacBio HiFi reads和Hi-C支架构建实现,得到了高连续性的染色体水平组装。我们实施了一个综合注释流程,将来自马铃薯栽培种Phureja DM参考基因组的基因模型和功能注释与RNA-seq reads相结合,以提供高质量的基因和转录本注释。此外,我们使用牛津纳米孔reads提供了全基因组DNA甲基化图谱,有助于深入了解马铃薯表观遗传学。组装好的基因组、注释、甲基化和表达数据在一个可公开访问的基因组浏览器中可视化,为马铃薯研究群体提供了宝贵资源。
