...s. If the pollen is too closely related and therefore incompatible, the vacuolar compartments are somehow disrupted, and the S-RNases released to the cytosol begin to destroy the RNA of the pollen tubes, in effect, killing them. However, S-specific matching between S-RNase and SLF, by itself is not suffici...
