Recently，Teachers and students of Beijing Agricultural College and Institute of Biotechnology, Bet365 games Academy of Agricultural Sciences published an article in the well-known academic journal GigaScience (IF 9.2) published a paper titled "Revealing the Evolution and Adaptability of Lycopodium Plants through the Chromosome-level Reference Genome of Tetraploid" (Chromosome-level reference genome of tetraploidIsoetes sinensisResearch paper that provides insights into evolution and adaption of lycophytes。This study mapped the first high-quality Bet365 games (Isoetes sinensis) Genome，This is also the first tetraploid genome reported to be assembled at the chromosome level of a non-seed plant。This study provides an important basis for further analysis of the evolution and environmental adaptability of lycophytes and the protection of Bet365 games。Beijing Agricultural College is the first unit，bet365 online casinoTeacher Cui Jinteng, senior laboratory engineer of the School of Landscape Architecture, and visiting graduate student of the Institute of Biotechnology, Chinese Academy of Agricultural Sciences、Zhu Yunke of Gezhi Boya Biotechnology is the first author of the paper，Researcher Liang Zhe from the Institute of Biotechnology, Chinese Academy of Agricultural Sciences is the corresponding author of the paper，Sisi Qian, an undergraduate of the Forestry College on our campus、Wang Shuxin、Cui Wenwen participated in this research work。

Bet365 games (Isoetes sinensis) is considered the "giant panda of the plant world"，is the first batch of Class I key protected wild plants announced in my country，It is also a lycophyte plant unique to China。In all vascular plant groups，Lycophytes have the longest evolutionary history，To Earth’s Biodiversity、Soil formation and carbon dioxide fixation have an important impact。However，Compared to seed plants，The distribution area of ​​lycopods has been greatly reduced，Several species of Lycopodium are endangered。Bet365 games is an ancient tetraploid (2n = 4x = 44) aquatic lycophyte。Bet365 games was once widely distributed，But now it has disappeared from most of its habitat。Drawing of the genome map of Bet365 games，In-depth understanding of the evolution and environmental adaptability of lycophytes，And it is of great significance bet365 online sports betting liveto the protection of Bet365 games。

This research combines the second generation、Three-generation genome sequencing and Hi-C data，Assembled containing 22 chromosomes 2.13 Gb Bet365 games tetraploid genome，its scaffold N50 reaches 86.66 Mb。 Comparative analysis with the closely related diploid Taiwan water leek，Revealed the characteristics of the tetraploid genome and polyploidy of Lycopodium lycopersicum and the similarities and differences in the sedum acid metabolism pathway and stomatal development of Bet365 games and Taiwan water leek。Comparative analysis with evolutionarily representative species，Discover some common genetic regulatory characteristics of Bet365 games，such as transcriptional regulation、Abscisic acid、Cytokinin、Ethylene、Jasmonic acid and gibberellin signaling pathways, etc.。On the other hand，Some involved strigolactones were also found、Salicylic acid metabolism and stress response (cold、Drought、Important genes related to salinity and cadmium，"Lost" in Bet365 games and many lycophytes。These findings provide new insights into the development of lycophyte plants and their adaptability to adverse stress，Provides important information for the protection of Bet365 games。
