Dioecy, the coexistence of separate male and female individuals in a population, is a rare
but phylogenetically widespread sexual system in flowering plants. While research has …

Monoecious or dioecious trees, shrubs, or herbs, sometimes succulent or scandent; stems
with or without laticifers; indumentum simple, malphighiaceous, stellate, or lepidote …

Parsimony and Bayesian analyses of plastid rbcL and trnL‐F DNA sequence data of the
pantropical family Euphorbiaceae sensu stricto (ss) are presented. Sampling includes …

The evolutionary transition from hermaphroditism (combined sexes) to dioecy (separate
sexes) is associated with whole genome duplication (polyploidy) in several flowering plant …

Parsimony, likelihood, and Bayesian analyses of nuclear ITS and plastid trnL‐F DNA
sequence data are presented for the giant genus Croton (Euphorbiaceae ss) and related …

Neutral genetic diversity gradients have long been used to infer the colonization history of
species [1, 2], but range expansion may also influence the efficacy of natural selection and …

The evolutionary success of polyploidy most directly requires the ability of polyploid
individuals to reproduce and transmit their genes to subsequent generations. As a result, the …

For many applications in population genetics, codominant simple sequence repeats (SSRs)
may have substantial advantages over dominant anonymous markers such as amplified …

Androdioecy is an unusual breeding system in which populations consist of separate male
and hermaphrodite individuals. The evolution of androdioecy is still poorly understood; …

Suppressed recombination allows divergence between homologous sex chromosomes and
the functionality of their genes. Here, we reveal patterns of the earliest stages of sex …
