Polyploids—organisms that have multiple sets of chromosomes—are common in certain
plant and animal taxa, and can be surprisingly stable. The evidence that has emerged from …

Understanding the maintenance of sexual reproduction constitutes a difficult problem for
evolutionary biologists because of the immediate costs that sex seems to incur. Typically …

Unisexual animals are commonly found in some polyploid species complexes, and most of
these species have had a long evolutionary history. However, their method for avoiding …

Of the 340 genera in the Brassicaceae, apomictic reproduction is found only in the North
American genus Boechera. We investigated phylogenetic relationships, ability to hybridize …

The association between polyploidy and reproduction transition, which is an intriguing issue
in evolutionary genetics, can also be exploited as an approach for genetic improvement in …

Genetic variation within apomictic organisms, as a raw material for evolutionary change, has
been underestimated in the past. Here we present a review of population studies using …

Hawthorns and medlars are closely related genera in Rosaceae subfamily Maloideae,
whose taxonomy remains poorly understood. Gametophytic apomixis occurs in polyploids …

DNA methylation is an epigenetic mechanism that has the potential to affect plant
phenotypes and that is responsive to environmental and genomic stresses such as …

Deciphering species relationships and hybrid origins in polyploid agamic species
complexes is notoriously difficult. In this study of cheilanthoid ferns, we demonstrate …

• Premise of study: Weeds cause considerable environmental and economic damage.
However, genomic characterization of weeds has lagged behind that of model plants and …
