The gene plays an essential role in the gametophytic self-incompatibility (GSI) system of . It codes for the stylar-expressed S-RNase protein which inhibits the growth of incompatible pollen tubes through cytotoxicity and the induction of programmed cell death in the pollen tube. While research on the GSI system has primarily focused on the gene, there is still a lack of insight into its spatiotemporal expression profile and the factors that regulate it.

This assay provides a valuable addition to existing tools in GSI research. The gametophytic self-incompatibility (GSI) system in Pyrus inhibits fertilization by pollen that shares one of the two S-alleles of the style.
