Background Amaranthus L. is a diverse genus consisting of domesticated, weedy, and non-
invasive species distributed around the world. Nine species are dioecious, of which …

Polyploidy results from whole-genome duplication and is a unique form of heritable variation
with pronounced evolutionary implications. Different ploidy levels, or cytotypes, can exist …

premise Invasive species are expected to undergo a reduction in genetic diversity due to
founder effects, which should limit their ability to adapt to new habitats. Still, many invasive …

Most crop plants, including sugar beet (Beta vulgaris subsp. vulgaris), suffer from
domestication bottlenecks and low genetic diversity caused by extensive selection for few …

Medicinal plants have long played a crucial role in healthcare systems, but limited genomic
information on these species has impeded the integration of modern biological technologies …

Anthropogenic activities, such as the movement of plants through greening, can result in
genetic disturbance that can interfere with local adaptation in wild populations. Although …

Many commonly studied species now have more than one chromosome-scale genome
assembly, revealing a large amount of genetic diversity previously missed by approaches …

At the molecular level, most evolution is expected to be neutral. A key prediction of this
expectation is that the level of genetic diversity in a population should scale with population …

Many invasive grasses drastically transform the ecosystems they invade, putting native
communities across the globe at risk (Fusco et al., 2019). Climate change will likely increase …

Background: Understanding population structure within species provides information on
connections among different populations and how they evolve over time. This knowledge is …
