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

The emblem of the heterostylous syndrome is the positioning at equivalent levels of the
stigmas of one floral morph and the anthers of one or two alternate morphs. Of less …

Self-incompatibility is an inherited ability of a flower to reject its own pollen. This trait
effectively prevents inbreeding and promotes outcrossing. In the absence of self …

Abstract Background The flowering plant Primula veris is a common spring blooming
perennial that is widely cultivated throughout Europe. This species is an established model …

Summary In 1862, Charles Darwin published his landmark study on the different forms of
flower in Primula; he coined the term distyly and subsequently expanded his studies to other …

Self-incompatible flowering plants are often classified into two major categories, depending
on whether mating types in populations are morphologically alike or unlike (Fisher and …

The inhibition sites for within‐morph incompatibility are reported for 52 species of Primula.
Pollen tube inhibition usually occurs at more than one site; when only one site is involved …

The view put forward by some authors that flowering plant self-incompatibility mechanisms
of the homomorphic sporophytic and heteromorphic sporophytic types have a close …

Distyly, a floral dimorphism associated with heteromorphic self-incompatibility and controlled
by the S-locus supergene, evolved independently multiple times. Comparative analyses of …
