高质量染色体版本的簸箕柳参考基因组组装

该数据是林木次生生长的分子调控和环境胁迫机制项目论文，数据内容是高质量染色体版本的簸箕柳参考基因组组装。簸箕柳是一种原产我国的当年开花的灌木柳，杨树的姊妹种，具有速生丰产、轮伐期短、个体较小，易于繁殖等特点，是重要的生物质能源和造林用材树种。灌木柳地理分布广泛，能适应不同的生态环境，存在丰富的自然变异，是研究林木遗传育种的理想材料。本研究综合利用三代PacBio测序和Hi-C技术，获得了一个高质量染色体版本的簸箕柳参考基因组。新组装的簸箕柳基因组大小为356 Mb，Contig N50为263,908bp，是先前版本的65倍，注释了36,937个蛋白编码基因，95.29%的簸箕柳基因组序列能够挂载到19条染色体上。新组装的簸箕柳具有更高的连续性和完整性，将更有助于杨柳科物种比较基因组的研究，并为木本植物研究提供了高质量的基因组资源。

This dataset corresponds to the research paper on molecular regulation of secondary growth and environmental stress response mechanisms in forest trees, with the core content being the high-quality chromosome-level reference genome assembly of Salix suchowensis. Salix suchowensis is a shrubby willow native to China that flowers in the same growth year, and is the sister species of poplars. It boasts traits such as rapid growth, high yield, short rotation cycle, small individual size and easy propagation, making it an important species for biomass energy production and afforestation timber use. This species has a wide geographical distribution, can adapt to various ecological environments, and exhibits rich natural variation, rendering it an ideal material for forest tree genetic breeding research. In this study, we integrated third-generation PacBio sequencing and Hi-C technologies to generate a high-quality chromosome-level reference genome assembly for Salix suchowensis. The newly assembled Salix suchowensis genome has a total size of 356 Mb, with a Contig N50 of 263,908 bp, which is 65-fold that of the previous assembly. A total of 36,937 protein-coding genes were annotated, and 95.29% of the genome sequences could be anchored onto 19 chromosomes. The newly assembled genome exhibits higher continuity and completeness, which will greatly facilitate comparative genomic studies on Salicaceae species and provide high-quality genomic resources for woody plant research.
