Abstract
Dipteris is a relic plant genus and an important indicator of global climate warming and plant geography during the Mesozoic era. However, the lack of genomic resources has hindered the study of paleoclimate, systematic evolution, and medicinal value of this genus. Here, we sequenced and assembled the first chromosome-level genome of Dipteris shenzhenensis. The assembled genome was 1.9 Gb with a contig N50 length of 4.75 Mb, GC content of 42.28% and BUSCO value of 98.3%, and 98.37% of the assembled sequences were anchored onto 33 pseudochromosomes. 71.97% of the genome were predicted to be repetitive sequences, and 45 telomeres were identified, including 15 paired telomeres. A total of 26,471 protein coding genes were predicted, of which 24,485 (92.5%) genes were functionally annotated. The first high-quality genome of Dipteris will provide important genome resources for understanding the systematic evolution, paleoclimate and medicinal value of ferns.
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.
