Since Darwinian times considerable knowledge has accumulated on the distribution,
physiology and genetics of self-incompatibility (SI) in higher plants. In the second half of this …

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 …

FLOWERING plants have evolved various stratagems to prevent inbreeding and promote
outcrosses1. One such mechanism, gametophytic self-incompatibility, provides a genetic …

Pollen–pistil interactions are crucial for controlling plant mating. For example, S-RNase-
based self-incompatibility prevents inbreeding in diverse angiosperm species. S-RNases …

▪ 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 …

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 (SI) prevents the production of “self” seed and inbreeding by providing a
recognition and rejection system for “self,” or genetically identical, pollen. Studies of …

Although S-locus RNases (S-RNases) determine the specificity of pollen rejection in self-
incompatible (SI) solanaceous plants, they alone are not sufficient to cause S-allele-specific …

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