Plant regeneration occurs when plants repair or replace damaged structures based on the
totipotency and pluripotency of their cells. Tissue culture is one of the most widely used …

The classification of reproductive isolating barriers laid out by Dobzhansky and Mayr has
motivated and structured decades of research on speciation. We argue, however, that this …

The tree of life is highly reticulate, with the history of population divergence emerging from
populations of gene phylogenies that reflect histories of introgression, lineage sorting and …

Given the explosive development of new molecular marker techniques over the last decade,
newcomers and experts alike in the field of DNA fingerprinting will find an easy-to-follow …

The nature and timing of evolution of niche differentiation among closely related species
remains an important question in ecology and evolution. The American live oak clade …

Previous phylogenetic studies in oaks (Quercus, Fagaceae) have failed to resolve the
backbone topology of the genus with strong support. Here, we utilize next-generation …

Background Analysis of interspecific gene flow is crucial for the understanding of speciation
processes and maintenance of species integrity. Oaks (genus Quercus, Fagaceae) are …

Hybridization can facilitate both evolutionary diversification and extinction and has had a
critical role in plant evolution, with c. 25% of species known to hybridize in some temperate …

Hybrid zones provide interesting systems to study genetic and ecological interaction
between different species. The correct identification of hybrids is necessary to understand …

Powerful and accurate detection of first-generation (F1) hybrids and backcrosses in nature is
needed to achieve a better understanding of the function and dynamics of introgression. To …
