Abstract
Gametophytic refers to the fact that the self incompatibility phenotype of the pollen is determined by its own (haploid) S-genotype. The subject is considered under the following headings: distribution of gametophytic self incompatibility (GSI), biology of GSI, molecular genetics of GSI, ribonuclease activity of the S-glycoproteins, localization of the S-RNases within the pistil tissue, role of S-RNases in arrest of pollen tube growth, nature of the pollen S-allele product, signal transduction during self incompatibility, glycosylation of S-RNases of N. alata, and relationship between S-RNases and other RNases.
