NKA-α, SLC26A6, SLC4A4 mRNA expression levels in the mid-intestine of Gymnocypris przewalskii at different time points (4:00, 10:00, 16:00 and 22:00) exposed to saline-alkaline lake water with a salinity of 17. Light–dark cycle was 14:10-h light:dark (5:00–19:00 with light intensity of 600–1000 lx;19:00–5:00 with light intensity of 0 lx); Lowercase indicates significantly difference among time points in each treatment (P < 0.05).
