Armeniaca cathayana, a new species described in 2010, belongs to gametophytic self-incompatibility (GSI) system which is under S-allele control. One new non-S-ribonuclease (non-S-RNase) was found in A. cathayana through comparing its nucleotide and amino acid sequences with sequences of the S-allele in Genbank. The BLAST analysis showed that the one new non-S-RNase S68-RNase (GenBank Accession No. MH155952) had the highest 96% nucleotide sequence homology with Prunus webbii non-S-RNase PW1 (EU809938.1). Alignment of deduced amino acid sequences of A. cathayana S68-RNase shared 83% similarity with P. webbii PW1. The new non-S-RNase determined in this study will provide new information to GSI of Rosaceae.

Keywords: Armeniaca cathayana; gametophytic self-incompatibility; non-S-RNase homology
