| Abstract: | In Rosa chinensis‘Slater’s Crimson China’and Rosa sp.‘2015-58-20’,the fluorescence microscope observation of pollen tubes in both self-pollinated and cross-pollinated styles indicated that rose is a typical gametophyte self-incompatible plant.The full-length sequence of RcS1-RNase and RcS2-RNase cDNA and DNA have been identified in the‘Slater’s Crimson China’.Sequence analysis showed that RcS1-RNase and RcS 2-RNase have five conserved domains(C1,C2,C3,RC4 and C5)and a hypervariable region.Phylogenetic analysis found that RcS-RNase has high homology with S-RNase proteins in other Rosaceae plants.Tissue specific expression analysis indicated that RcS1-RNase and RcS2-RNase genes are solely expressed in styles. |
