    Do homomorphic and heteromorphic self-incompatibility systems have the same sporophytic mechanism? (1986)

    Notes: Abstract The view put forward by some authors that flowering plant self-incompatibility mechanisms of the homomorphic sporophytic and heteromorphic sporophytic types have a close evolutionary relationship, with one form being evolved from the other, or both forms directly evolved from ancestors with homomorphic gametophytic incompatibility, is challenged. A review is provided of the various facets of each of the three main self-incompatibility systems, including a detailed summary of our current knowledge of the rejection mechanism, to demonstrate that the implicit assumption that these systems have a common S locus, and also evolutionary theories linking the systems, need to be treated with considerable caution.

    Contrasting breeding systems in twoEriotheca (Bombacaceae) species of the Brazilian cerrados (1992)
    Springer
    Plant systematics and evolution 179 (1992), S. 207-219

    Keywords: Angiosperms ; Eriotheca ; Bombacaceae ; Anthophoridae ; Neotropical savanna ; bee pollination ; polyembryony ; apomixis ; polyploidy

    Topics: Biology
    Notes: Abstract The pollination biology and breeding systems ofEriotheca pubescens andE. gracilipes have been studied. These two species occur as trees in cerrado vegetation, the neotropical savannas of Central Brazil, with partially sympatric distributions. They have similar phenology and floral structure, although the flowers ofE. pubescens are larger. Both species have nectar flowers pollinated by largeAnthophoridae bees but the main pollinators of each species differ in size. The species have markedly different breeding systems: late-acting self-incompatibility inE. gracilipes and apomixis stimulated by pollination inE. pubescens.
