Description

The system with the broadest taxonomic distribution, which we term type-1 SI, is gametophytic and based on linked pistil S S-RNase and pollen S S-locus F-box (SLF)/S-haplotype-specific F-box (SFB). So far, type-1 SI has been found in four eudicot families: Solanaceae, Plantaginaceae, Rosaceae, and Rutaceae. After pollination, both S1- and S2-RNases can enter pollen tubes and be recognized by S1- or S3-SLFs, but only SCFS3-SLF complexes can ubiquitinate these S-RNases leading to their degradation by 26S proteasome, with the survived S1-RNase in S1 pollen tubes forming the S-RNase condensates (SRCs) resulting in self-pollen inhibition.
