<b>chromosome-level genome assembly </b><b>of the mud carp (</b><b><i>Cirrhinus molitorella</i></b><b>)</b>

We constructed high-quality chromosome-level genome assembly of C. molitorella using PacBio sequencing and Hi-C data. The evolutionary history of C. molitorella was studied by inferring dynamic changes of ancestral population sizes. The genetic basis of adaptation in C. molitorella was dissected by performing gene family expansion and contraction analyses and identifying positively selected genes (PSGs). This provides the basis for the ecological adaptability of C. molitorella.本研究借助PacBio测序（PacBio sequencing）与Hi-C数据（Hi-C data），构建了鲮鱼（C. molitorella）的高质量染色体级基因组组装。在此基础上，本研究通过推断祖先种群规模的动态变化，解析了鲮鱼的演化历史；同时通过开展基因家族扩张与收缩分析并鉴定正选择基因（positively selected genes, PSGs），剖析了鲮鱼适应性演化的遗传基础。上述研究成果为鲮鱼的生态适应性研究奠定了重要基础。
