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 …

House mice prefer mates genetically dissimilar at the major histocompatibility complex
(MHC). The highly polymorphic MHC genes control immunological self/nonself recognition; …

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

Male fertility was restored to genetically engineered male sterile oilseed rape plants. Male
sterile plants that express a chimaeric ribonuclease gene in the anther tapetal cell layer …

The author offers an overview of pollen biology and biotechnology for students and
researchers in areas such as reproductive biology, biotechnology, aeropalynology, plant …

MANY angiosperms employ self-incompatibility systems to prevent inbreeding1, 2. The
simple genetics of such systems3–6 have made them attractive models of plant cellular …

Screening of a yeast two-hybrid library for proteins that interact with the kinase domain of an
S-locus receptor kinase (SRK) resulted in the isolation of a plant protein called ARC1 (A rm …

Heterostyly is a genetic polymorphism in which plant populations are composed of two
(distyly) or three (tristyly) morphs that differ reciprocally in the heights of stigmas and anthers …

S proteins, pistil-specific ribonucleases that cosegregate with S alleles, have previously
been shown to control rejection of self-pollen in Petunia inflata and Nicotiana alata, two …

Several self-compatible species of higher plants, such as Arabidopsis thaliana, have
recently been found to contain S-like RNases. These S-like RNases are homologous to the …
