Molecular mechanisms of self-incompatibility in flowering plants and fungi - different means to the same end.
Hermaphrodite flowering plants and fungi face the same sexual dilemma - how to avoid self-fertilization. Both have evolved ingenious recognition systems that reduce or eliminate the possibility of selfing. These self-incompatibility (SI) systems offer unique opportunities to study recognition and signalling in non-animal cells and also represent model systems for studying the evolution of breeding systems at a molecular level. In this review, the authors discuss recent molecular data that predict an astonishing diversity in the cellular mechanisms of SI operating in flowering plants and fungi.
