    ..Recombinant protein of the cDNA clone showing sequence similarity to LTP was demonstrated to bind IgE of a patient allergic to Brassica pollen. The cDNA clone reported here, therefore, represents a novel pollen allergen of Brassica rapa...
  8. Sato Y, Fujimoto R, Toriyama K, Nishio T. Commonality of self-recognition specificity of S haplotypes between Brassica oleracea and Brassica rapa. Plant Mol Biol. 2003;52:617-26 pubmed
    ..Comparing deduced amino-acid sequences of SP11 proteins and SRK proteins in the pairs, regions of SP11 and SRK important for self-recognition are discussed. ..
  9. Sato Y, Okamoto S, Nishio T. Diversification and alteration of recognition specificity of the pollen ligand SP11/SCR in self-incompatibility of Brassica and Raphanus. Plant Cell. 2004;16:3230-41 pubmed
    ..These results suggest that Regions III and Region V of SP11 are important for determining the recognition specificity, but not the sole determinant. A possible process of the generation of a new S haplotype is herein discussed...

    ..Two other S genotypes in B. napus also had non-functional class I S haplotypes together with recessive BnS-6. These observations suggest independent origins of self-compatibility in B. napus...

    ..Down-regulation of DCW11 and up-regulation of AOX1a were also observed in two other types of rice CMS. Our result indicates that DCW11 could play a role as a mitochondrial signal transduction mediator in pollen germination. ..
