A putative CsS-RNase gene (KU852488) was cloned and characterized in Camellia sinensis.
The CsS-RNase is primarily expressed in the styles.
The expression of CsS-RNase in self-pollinated styles was up-regulated earlier than the crossed treatments.
The amino acid sequences of CsS-RNase were polymorphic in different tea cultivars.
The CsS-RNase was mapped on a genetic linkage map of C. sinensis.
