Genome of striped eel catfish(Plotosus lineatus) provides insights into the adaptive evolution of amphidromous fish

DEAR EDITOR,Dramatic changes in habitat can have a range of effects on organisms(Bi & Zhang, 2021). Plotosus lineatus is a representative fish within Ostariophysi showing adaptation from freshwater habitats to the ocean. Here, we sequenced the genome of P. lineatus using long-read and Hi-C sequencing technology. Based on the high-quality chromosome-level genome, we explored the molecular basis of various P. lineatus features, including large genome with fewer chromosomes, novel dendritic organ(DO),
