Cellular and Molecular Biology of Self-Incompatibility
Systematic efforts to identify and understand the cellular and molecular bases of self-incompatibility (SI) were initiated at the start of the second half of the twentieth century with the very first investigations regarding the involvement of glycoproteins in pollen-pistil relationships (Linskens 1954, 1955, 1958, 1960). From then on, Linskens (1961, 1962, 1964, 1975, 1986, 1988), who undertook an important part of the early work in the biochemistry of SI, regularly reviewed the state of the art and continued to contribute actively to research on the differential evolution of selfed, cross-pollinated and castrated buds and flowers and their RNA, amino acid (AA; Tupý 1961) and specific protein contents. New models of the recognition mechanisms, particularly those of Lewis (1965) and Ascher (1966) — both of which were inspired by earlier suggestions from Straub (1946, 1947) — and of Linskens (1965) began to flourish.
