Y. Zhao, Wang, J., Thammaratsuntorn, J., Wu, J. W., Wei, J. H., Wang, Y., Xu, J. W., and Zhao, J. L., Comparative transcriptome analysis of Nile tilapia (Oreochromis niloticus) in response to alkalinity stress, vol. 14, pp. 17916-17926, 2015.

To identify genes of potential importance to alkalinity tolerance, RNA sequencing (RNA-Seq) was performed to survey gill transcriptome profiles from freshwater (FW) and alkaline water (AW) exposed Nile tilapia (Oreochromis niloticus). A total of 22,724,036 (AW)/16,461,040 (FW) single-end reads were generated in which 20,304,348 (AW)/14,681,290 (FW) reads (90.0/89.72%) were aligned to the reference genome. Differential expression analysis revealed 302 up-regulated and 193 down-regulated genes between AW- and FW-exposed fish.

Transcriptomic profiles of Japanese medaka (Oryzias latipes) in response to alkalinity stress

Oryzias latipes (Adrianichthyidae), known as Japanese medaka or Japanese killifish, is a small 2-4 cm long fish common in rice paddies in coastal Southeast Asia and is also a popular aquarium fish. It has been widely used as a research model because of its small size and because it is very easy to rear. Alkalinity stress is considered to be one of the major stressors on fish in saline-alkaline water.
