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 …

The breakdown of self-incompatibility has occurred repeatedly throughout the evolution of
flowering plants and has profound impacts on the genetic structure of populations. Recent …

Self-incompatibility (SI) is an important mechanism that prevents self-fertilization and
inbreeding in flowering plants. The most widespread SI system utilizes S ribonucleases (S …

T2-type RNases are responsible for self-pollen recognition and rejection in three distantly
related families of flowering plants—the Solanaceae, Scrophulariaceae, and Rosaceae. We …

Loss of complex characters is thought to be irreversible (Dollo's law). However, hypotheses
of irreversible evolution are remarkably difficult to test, especially when character transitions …

Breakdown of self‐incompatibility occurs repeatedly in flowering plants with important
evolutionary consequences. In plant families in which self‐incompatibility is mediated by S …

The pollen and stigma are well adapted to generate micro-environments for pollen
germination, tube growth, fertilization and the avoidance of subvention of the pollination …

To elucidate the molecular basis of loss of self‐incompatibility in Lycopersicon, S‐RNases
and HT‐proteins were analysed in seven self‐compatible (SC) and three self‐incompatible …

S-RNase-based gametophytic self-incompatibility appears to be the most phylogenetically
widespread form of self-incompatibility found in the angiosperms, having been reported in …
