Evolutionary conflict can drive rapid adaptive evolution, sometimes called an arms race,
because each party needs to respond continually to the adaptations of the other. Evidence …

Species differentiation and the underlying genetics of reproductive isolation are central
topics in evolutionary biology. Hybrid sterility is one kind of reproductive barrier that can lead …

Understanding which reproductive barriers contribute to speciation is essential to
understanding the diversity of life on earth. Several contemporary examples of strong hybrid …

The fundamental molecular basis for phenotypic and genetic similarities among many
described cases of plant hybrid necrosis has not been fully described. Plants can be good …

Adaptation to local conditions likely plays an important role in plant diversity and speciation.
A fuller understanding of the role of adaptation in speciation requires connecting particular …

Flowering plants display spectacular floral diversity and a bewildering array of reproductive
adaptations that promote mating, particularly outbreeding. A striking feature of this diversity …

Polyploidy is commonly thought to be associated with the domestication process because of
its concurrence with agriculturally favourable traits and because it is widespread among the …

Reproductive compensation, the replacement of dead embryos by potentially viable ones, is
known to play a major role in the maintenance of deleterious mutations in mammalian …

This special Highlight section of Annals of Botany contains seven papers that show the rapid
progress in understanding the genetics related to plant evolution–identifying genes that …

Clonal plants are widespread throughout the plant kingdom and dominate in diverse
habitats. Spatiotemporal heterogeneity of environment is pervasive at multiple scales, even …
