Classical genetic and molecular data show that genes determining disease resistance in
plants are frequently clustered in the genome. Genes for resistance (R genes) to diverse …

The majority of flowering plants produce perfect flowers that contain both the male and
female reproductive organs in close proximity; consequently, they would have a strong …

Advances in plant cell molecular biology have considerably increased our understanding of
pollen-pistil barriers, particularly those operated by incompatibility mechanisms, and, at the …

In many plant species, self-incompatibility (SI) is genetically controlled by a single
multiallelic S locus. Previous analysis of S alleles in the Solanaceae, in which S locus …

Stylar riboncleases (RNases) are associated with gametophytic self-incompatibility in two
plant families, the Solanaceae and the Rosaceae. The self-incompatibility-associated …

▪ Abstract Many bisexual flowering plants possess a reproductive strategy called self-
incompatibility (SI) that enables the female tissue (the pistil) to reject self but accept non-self …

Complementary DNA clones representing two alleles of the self-incompatibility (S) locus of
apple (Malus× domestica Borkh.) have been isolated and characterised. One of the alleles …

Self-incompatibility (SI) is one of the mechanisms that have evolved to encourage
outbreeding in flowering plants and is defined as “the inability of a fertile hermaphrodite …

Self-incompatibility is a widespread mechanism in flowering plants that prevents inbreeding
and promotes outcrossing. The self-incompatibility response is genetically controlled by one …

Stylar proteins of 13 almond (Prunus dulcis) cultivars with known S-genotypes were
surveyed by IEF and 2D-PAGE combined with immunoblot and N-terminal amino acid …
