白冠麻雀（Zonotrichia leucophrys）是一种分布广泛、对环境变化有广泛适应能力的雀形目鸟类。它历史上一直是鸟类生态学、生理学和行为研究中的模式物种。在这里，我们使用 PacBio 和 OmniC 测序数据展示了 Zonotrichia leucophrys 的高质量染色体水平基因组。通过结合来自肝脏、下丘脑和卵巢的 RNA-seq 和 Iso-seq 数据构建基因模型。总共生成了 1,123,996,003bp 的基因组，包括组装在完整支架中的 31 条染色体以及其他未放置的支架。这种高质量的基因组组装为研究界使用白冠麻雀作为了解鸟类基因组生物学和发育的模型提供了重要的基因组资源，并为未来的基础和应用研究提供了基因组基础。
The white-crowned sparrow, Zonotrichia leucophrys, is a passerine bird with a wide distribution and it is extensively adapted to environmental changes. It has historically acted as a model species in studies on avian ecology, physiology and behaviour. Here, we present a high-quality chromosome-level genome of Zonotrichia leucophrys using PacBio and OmniC sequencing data. Gene models were constructed by combining RNA-seq and Iso-seq data from liver, hypothalamus, and ovary. In total a 1,123,996,003 bp genome was generated, including 31 chromosomes assembled in complete scaffolds along with other, unplaced scaffolds. This high-quality genome assembly offers an important genomic resource for the research community using the white-crowned sparrow as a model for understanding avian genome biology and development, and provides a genomic basis for future studies, both fundamental and applied.
