CircRNA-seq of salt stress cucumber (Cucumis sativus L.)

Cucumber is an important controlled-environment horticultural crop and is fairly sensitive to salinity. And, there is still no evidence showing the role of circRNAs, a new type of non-coding RNAs, in the salt stress resistance of cucumber. Besides, although genome-wide identification of circRNAs has been performed in a lot of plant species, the characteristics and functions of circRNAs are not clear in cucumber. Our study firstly focuses on identification and characterization of circRNAs in cucumber in response to salt stress and then uncovered a potential functional role of circRNAs in the regulation of salt stress response.
