“…Transcriptome differences among 8 psu, 16 psu and the freshwater environment are not sufficiently stressful to activate the pathways that are involved in the stable-then-change category. These regulatory pathways can adapt to a low salinity environment when the salinity reaches a threshold that these paths cannot withstand the change and result in functional adaptation at the transcriptional level [ 73 , 74 ].…”

“…Similarly, a considerable number of genes were identified encoding energy-dependent ATP-binding transporters (atp1a3, atp2a2, atp2a3) and voltagegated ion channels (scn1b, kcna2/3/10).. Among these genes, atp1a3 that codes Na + /K + -ATPase plays a key role in the Na + and K + gradient balance, and this gene has been reported as being differentially expressed in salinity-varying environments in T. obscurus [18]. The voltage-gated ion channel genes (scn1b and kcna family) have been discovered by differential gene expression during spawning [34] and selective sweeps adapting freshwater and alkaline waters in Amur Ide [35,36].…”

“…Na + /K + -ATPase (NKA), as a key enzyme of ion transport maintaining the 4 Na + and K + gradient, is mainly distributed in the chloride cells of the gills and has a crucial function in the ion exchange and osmoregulation in T. obscurus [17]. The activity of NKA changes dramatically with the variation of environmental salinity [18]. In hypoosmotic environments, the intestine plays a pivotal osmoregulatory role in absorbing water and balancing ions through the intestinal epithelia [14].…”
