Abstract
Partial genomic and cDNA sequences of the RNase alleles S1, S7, S8 and Sf were obtained from Prunus dulcis cvs ’Ne Plus Ultra’, ’Ferragnes’ and ’Nonpareil’ 15–1, and IRTA Selection 12–2. Total DNA was extracted from leaves, and cDNA was prepared from total RNA extracted from styles. The partial cDNA sequences of the S1 allele from ’Ferragnes’, and the S7 and S8 alleles from ’Nonpareil’ 15–1, matched those reported in the literature for the alleles Sb, Sc and Sd respectively. The sequences of the S1, S7, S8 and Sf alleles found in genomic DNA contained introns of 562, 1,530, 2,208 and 689 bp respectively. The exon/intron splice junction sites of all alleles followed the GT/AG consensus sequence rule, and the sequences were found to be highly conserved.
