Completely outside the two systems is Theobroma cacao which must be
mentioned because it has been reported by Knight and Rogers (1955) that a
major sporophytic S gene is operating but later statements implicate additional

This is self-incompatibility, of which there are three major types: gametophytic.
homomorphic sporophytic and hetero- morphic sporophytic. In all cases,
prevention of self-fertilisation is due to expressed alleles common to both parents

Molecular Genetics of Plant Development
In sporophytic self-incompatibility, the genotype of the plant (sporophyte) from
which the pollen is derived determines whether the pollen will be rejected or not.
In this type of self-incompatibility, development of the pollen is usually blocked on

Natural Hybridization and Evolution
If the alleles are expressed co-dominantly, matemal plants with either of the
alleles of the pollen parent will reject pollen under sporophytic 51. In contrast,
plants that exhibit gametophytic 51 reject only those pollen grains that possess
one of ...

Incompatibility and Incongruity in Wild and Cultivated Plants
The finding is remarkable, because it shows that the ovule, and not only the male
gametophyte, can be a target of SI and because it suggests long-distance
messaging between tube tips and young ovules. n 2.4 Sporophytic-Gametophytic

In other words, behaviour is controlled by the diploid sporophyte (sporophytic
control). Work by Correns (1912, 1913) on Cardamine pratensis showed that a
similar inheritance of a di-allelic sporophytic incompatibility system could occur in

The view that gametophytic self-incompatibility is phylogenetically primitive
whereas sporophytic self-incompatibility is derived has recently been challenged
by Zavada134 and Zavada and Taylor135 on the basis of fossil evidence.
