Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

Ecology affects each of the three principal processes leading to speciation: genetic
differentiation among populations within species, acquisition of reproductive isolation …

DNA methylation can cause heritable phenotypic modifications in the absence of changes in
DNA sequence. Environmental stresses can trigger methylation changes and this may have …

Allopolyploidy is an evolutionary and mechanistically intriguing process, in that it entails the
reconciliation of two or more sets of diverged genomes and regulatory interactions. In this …

Whole genome duplication (leading to polyploidy) is widely accepted as an important
evolutionary force in plants, but it is less recognized as a driver of animal diversification …

Here, we describe the evolution of gene expression among a diversified cohort of five
allopolyploid species in the cotton genus (Gossypium). Using this phylogenetic framework …

Epigenetic information includes heritable signals that modulate gene expression but are not
encoded in the primary nucleotide sequence. We have studied natural epigenetic variation …

Hybridization plays a central role in plant evolution, but its overall importance in fungi is
unknown. New plant pathogens are thought to arise by hybridization between formerly …

Being sessile organisms, plants show a high degree of developmental plasticity to cope with
a constantly changing environment. While plasticity in plants is largely controlled genetically …

For a holistic approach in developing the stress-resilient crops of the 21 st century, modern
genomic biology will need to re-envision the underappreciated phenomena in classical …
