Morphology, transcriptome and physiology analyses reveal adaptation mechanisms of Gymnocypris Przewalskii juveniles to saline-alkaline stresses.

ABSTRACT:

Background

Naked carp (Gymnocypris przewalskii), a fish endemic to Qinghai Lake, China, has attracted extensive attention for its adaptation to salinity and alkalinity stress. However, the survival mechanism of G. przewalskii against saline-alkaline water environments remains elusive. In this study, we aimed to reveal the causes of saline-alkaline tolerance of G. przewalskii through the analysis of morphological, physiological and transcriptomic dimensions. The combination of growth performance and physiological indexes, and the morphology of gill tissues and transcriptomics strengthened the connection between this experiment, and further explored and analyzed the causes of salinity tolerance of G. przewalskii.

Results

Analysis of growth indices revealed weight gain rate (WG
