Construction and analysis of telomere-to-telomere genomes for two sweet oranges: Longhuihong and Newhall (Citrus sinensis) (PRJCA026660)

The study de novo assembled two T2T reference genomes of sweet orange varieties exhibiting different levels of cold tolerance. These genomes serve as valuable foundational resources for genomic research and molecular breeding aimed at enhancing cold tolerance in sweet oranges. Additionally, they expand the existing repository of reference genomes and sequencing data resources for Citrus sinensis. Moreover, these genomes provide a critical data foundation for comparative genomics analyses across different plant species.

本研究从头组装了两个耐寒性存在差异的甜橙品种的端粒到端粒（Telomere-to-Telomere, T2T）参考基因组。上述基因组可为面向甜橙耐寒性改良的基因组学研究与分子育种工作提供宝贵的基础资源。此外，本研究还扩充了甜橙（Citrus sinensis）现有的参考基因组与测序数据资源库。同时，这些基因组还为跨植物物种的比较基因组学分析提供了关键的数据基础。
