PLANT BIOLOGY Going Forth to Multiply

Self-incompatibility, which assures cross-fertilization in plants, has many similarities to other eukaryotic self-nonself recognition systems. Molecular components involved in the self-incompatibility response in Brassica have been identified on the surface of both pollen and receptive stigma. Murase et al. (see the Perspective by Goring and Walker) have now identified another key component in the pathway, the membrane-anchored kinase MLPK, that functions early in the responsive signal transduction cascade after pollen encounters a stigma epidermis cell.
