Abstract

Poppies' self awareness Self-incompatibility is an important mechanism in many plant species, used to prevent inbreeding by ensuring rejection of 'self' pollen. It is controlled by a multi-allelic S locus, comprising pollen (male) and pistil (female) S determinants. Wheeler et al. have cloned three alleles of a highly polymorphic pollen-expressed gene, PrpS, from the common poppy Papaver rhoeas, which has no homologues in existing databases. PrpS is a transmembrane protein that appears to function as the pollen S-locus determinant. This adds to our knowledge of the evolution of cell–cell recognition systems.
