Abstract
Begonia fimbristipula Hance (Begoniaceae) is a valuable medicinal herb that is classified as a protected species in Guangdong Province, China. In this study, we present a chromosome-level genome assembly of B. fimbristipula, aiming to facilitate its conservation and utilization. The genome was assembled using a combination of Oxford Nanopore long-read data and Illumina short-read data. The assembled genome size of B. fimbristipula is 462.11 Mb, with a scaffold N50 of 38.22 Mb. A total of 91.96% (424.94 Mb) of the sequences were anchored to 11 pseudochromosomes using Hi-C technology. The genome assembly exhibits a BUSCO completeness of 90.3% and an LTR Assembly Index (LAI) of 17.73. Genome annotation revealed 25,563 protein-coding genes and 274 tRNA genes. The high-quality chromosome-level assembly and annotation provide valuable insights into the genomic characteristics of B. fimbristipula, thereby offering essential resources for its conservation and economic utilization.
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.
