Polyploids—organisms that have multiple sets of chromosomes—are common in certain
plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from …

Charles Darwin recognized that flowering plants have an unrivalled diversity of sexual
systems. Determining the ecological and genetic factors that govern sexual diversification in …

Polyploidy is a mutation with profound phenotypic consequences and thus hypothesized to
have transformative effects in plant ecology. This is most often considered in the context of …

A phylogeny of Solanaceae is presented based on the chloroplast DNA regions ndhF and
trnLF. With 89 genera and 190 species included, this represents a nearly comprehensive …

Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …

The vast majority of eukaryotic organisms reproduce sexually, yet the nature of the sexual

Pseudocereals are promising crops for coming decades keeping in view the global food
security. Amaranths are a leading group of plants among the pseudocereals that have the …

Polyploidy, the multiplication of chromosome sets above the diploid state, is arguably as
prevalent in plants as any other eukaryotic group. Over the past century, polyploidy has …

This unique volume combines discussion of plant evolution with that of crop origins. The first
