WebSome of the biochemical and molecular processes involved in the recognition and rejection of self-pollen, however, have become known only in the past 20 years, thanks to the development of molecular techniques, which have provided an answer to some of the many questions concerning SI. The best studied mechanisms of SI act by inhibiting the germination of pollen on stigmas, or the elongation of the pollen tube in the styles. These mechanisms are based on protein-protein interactions, and the best-understood mechanisms are controlled by a single locus termed S, which has many different alleles in the species population. Despite their similar morphological and genetic manifestations, these mechanisms have evolved independently, and are based on different cellul… hire rite fencing
