Self-Incompatibility Gene in Tomato

The tomato (Lycopersicon peruvianum) has a gametophytic self-incompatibility (GSI) mechanism controlled by a single genetic locus (S locus) with multiple alleles. S RNases, an allelic series of abundant stylar proteins, are products of the S locus in L. peruvianum and other Solanaceous plants. The S-11 RNase gene from L. pervuianum was introduced into a self-compatible (SC) species (Lycopersion esculentum) to examine whether the expression pattern in the heterologous host mimics that in L. peruvianum.

Expression of Gene in Transgenic Plants

The resultant transgenic L. esculentum plants expressed the introduced gene highly in their styles, which is similar to the expression in L. peruvianum.
