, a Grapsidae family member, can adapt to terrestrial and semi-terrestrial environments. This study used transcriptomic and microbiome analyses to explore its adaptation mechanisms. Transcriptome analysis showed gene changes related to cytoskeleton-motor, water-osmotic pressure, and energy metabolism. For example, was upregulated in the aquatic environment compared to the semi-terrestrial one, and was downregulated in some groups. and SLC6A3 were upregulated with osmotic regulation, and was upregulated when comparing the aquatic and semi-terrestrial habitats; at the same time, many energy-related genes were downregulated between the terrestrial and semi-terrestrial habitats. Regarding the gut microbiota, no significant differences in alpha diversity were found between habitats, but there were differences at the genus level. and were more abundant in the aquatic habitat, and in the semi-terrestrial one. These results provide insights into ' terrestrial adaptation, benefiting crustacean evolution study and aquaculture.
作为方蟹科的一员，能够适应陆地和半陆地环境。本研究采用转录组学和微生物组分析来探索其适应机制。转录组分析显示了与细胞骨架运动、水渗透压和能量代谢相关的基因变化。例如，与半陆地环境相比，在水生环境中上调，而在某些组中下调。和SLC6A3随着渗透调节而上调，并且在比较水生和半陆地栖息地时上调；同时，在陆地和半陆地栖息地之间，许多与能量相关的基因下调。关于肠道微生物群，在不同栖息地之间未发现α多样性的显著差异，但在属水平上存在差异。和在水生栖息地中更为丰富，而在半陆地栖息地中更为丰富。这些结果为的陆地适应提供了见解，有利于甲壳类动物进化研究和水产养殖。
