摘要

鸢尾草是世界上一种具有侵略性的水稻杂草。到目前为止，伊里亚锥虫的参考基因组尚未发表。在这里，我们基于Illumina， PacBio和Hi-C reads完成了C. iriia染色体水平的基因组组装。鸢尾花的基因组大小为479.08 Mb， N50为7.02 Mb。利用Hi-C支架合成了68条假染色体，占组装基因组的99.65%。预测的蛋白编码基因数量为47,395个，其中93.26%被注释，37.69%被鉴定出重复序列。本研究为鸢尾鸢尾的分子生物学研究和管理提供了宝贵的基因组资源。

Chromosome-level genome assembly of Cyperus iria, an aggressive weed of rice.

Cyperus iria is an aggressive weed of rice throughout the world. Until now, the reference genome of C. iria has not been published. Here, we completed the chromosome-level genome assembly of C. iria based on Illumina, PacBio and Hi-C reads. The assembled genome size of C. iria was 479.08 Mb with a contig N50 of 7.02 Mb. 68 pseudochromosomes were produced using Hi-C scaffolding, accounting for 99.65% of the assembled genome. The number of predicted protein-coding genes is 47,395, of which 93.26% were annotated, and 37.69% repetitive sequences were identified. Our study provided a valuable genomic resource for the molecular biology research and the management of C. iria.

期刊介绍： Scientific Data is an open-access journal focused on data, publishing descriptions of research datasets and articles on data sharing across natural sciences, medicine, engineering, and social sciences. Its goal is to enhance the sharing and reuse of scientific data, encourage broader data sharing, and acknowledge those who share their data. The journal primarily publishes Data Descriptors, which offer detailed descriptions of research datasets, including data collection methods and technical analyses validating data quality. These descriptors aim to facilitate data reuse rather than testing hypotheses or presenting new interpretations, methods, or in-depth analyses.
