Biological invasions impose ecological and economic problems on a global scale, but also
provide extraordinary opportunities for studying contemporary evolution. It is critical to …

Abstract With c. 24 700 species (10% of all flowering plants), Asteraceae are one of the
largest and most phenotypically diverse angiosperm families, with considerable economic …

Most diploid organisms have polyploid ancestors. The evolutionary process of
polyploidization is poorly understood but has frequently been conjectured to involve some …

Cytonuclear disruption may accompany allopolyploid evolution as a consequence of the
merger of different nuclear genomes in a cellular environment having only one set of …

Ferns are the second largest clade of vascular plants with over 10,000 species, yet the
generation of genomic resources for the group has lagged behind other major clades of …

The concept of invasion is useful across a broad range of contexts, spanning from the fine
scale landscape of cancer tumors up to the broader landscape of ecosystems. Invasion …

Allopolyploidization is a frequent evolutionary transition in plants that combines whole-
genome duplication (WGD) and interspecific hybridization. The genome of an allopolyploid …

Homeologue expression bias occurs when one progenitor copy of a gene is expressed at a
higher level than the other in allopolyploids. Morphological variation, including differences in …

Allopolyploidization entailing the merger of two distinct genomes in a single hybrid
organism, is an important process in plant evolution and a valuable tool in breeding …

Polyploidy is a prominent mechanism of plant speciation and adaptation, yet the mechanistic
understandings of duplicated gene regulation remain elusive. Chromatin structure dynamics …
