S-genotyping in Japanese plum by PCR and capillary gel electrophoresis detection

In this work a PCR S-genotyping method using capillary electrophoresis detection was assayed in Japanese plum. Sweet cherry primers designed for S-RNase and SFB intron length polymorphism detection by capillary electrophoresis were evaluated in Japanese plum cultivars. Amplification of both genes was successful and amplified sizes were correlated with Japanese plum S-alleles. The S-RNase genotype of 58 Japanese plum type cultivars previously determined by other methods was confirmed using this technology and the SFB alleles of these cultivars were also determined. Allele sizes of both genes are reported for 13 different S-alleles found in Japanese plum and will allow efficient S-genotype characterization in this species.
