Genome data for the draft assembly of the Chinese tertiary relict tree, Nyssa yunnanensis.
Dataset type: Genomic, Transcriptomic
Data released on July 31, 2020
Nyssa yunnanensis is a deciduous tree species in the family Nayssaceae within the order Cornales. With only eight individuals across two geographic sites recorded in the Yunnan province of China, this species was listed as a national grade-I protected species in China in 1999. It is also one of the 120 species in the Implementation Plan of Rescuing and Conserving China’s Plant Species with Extremely Small Populations (PSESP) (2011-2-15). N. yunnanensis has also been evaluated as Critically Endangered in the IUCN red list and Threatened Species List of China's Higher Plants. Hence understanding the genomic characteristics of this highly endangered Tertiary relict tree species is essential, especially for developing conservation strategies.
Here we present the draft genome assembly of N. yunnanensis. Using 10X genomics linked-reads sequencing data. We carried out the de novo assembly and annotation analysis. The N. yunnanensis genome assembly is 1475 Mb in length containing 288,519 scaffolds with an scaffold N50 length of 985.59 kb. 799.51 Mb of the assembled genome was identified as repetitive elements, accounting for 54.24% of the sequenced genome and a total of 39,803 protein-coding genes were predicted.
The genomic data of N. yunnanensis provided in this study will provide basic information for future genomic and evolutionary studies. With the genomic characteristics of N. yunnanensis available, our study might also facilitate future conservation biology studies to help protect this extremely threatened tree species.
