Abstract

cDNA clones for an S-allele, designated S5, of the self-incompatibility locus (S-locus) of Lycopersicon peruvianum have been isolated by probing a pistil cDNA library with cDNAs for S-alleles of Petunia inflata and Solanum chacoense. The longest S5-cDNA is 869 bp and contains an open reading frame of 217 amino acids. An alignment of the deduced amino acid sequence of S5-protein with that of the 18 S-proteins from five other solanaceous species is presented. Sequence comparison further refines the primary structural features of the S-proteins previously revealed from comparison of subsets of these sequences. Based on this comparison and evidence presented elsewhere, it is proposed that accumulation of point mutations, and not intragenic recombination, is responsible for the generation of new allelic specificities.
