Long a major focus of genetic research and breeding, sunflowers (H elianthus) are
emerging as an increasingly important experimental system for ecological and evolutionary …

The increased reproductive potential, size, shoot allocation, and growth rate of weedy plants
may result from reduced resource allocation to other aspects of plant growth and defense …

• Premise of the study: The sunflower genus Helianthus has long been recognized as
economically significant, containing species of agricultural and horticultural importance …

Shattercane (Sorghum bicolor (L.) Moench subsp. drummondii) and weedy sunflower
(Helianthus annuus L.) are two examples of crop wild relatives (CWRs) that have become …

Abstract Characterization of confectionary sunflower germplasm resources is critical to their
efficient collection and management as well as for breeding programs. Thirty six (36) …

Wild sunflower Helianthus annuus originates from North America and has naturalised in
Argentina where it is considered invasive. The present study attempts to assess the genetic …

Ahasl1 is a multilallelic locus where all the induced and natural mutations for herbicide
tolerance were described thus far in sunflower (Helianthus annuus L.). The allele Ahasl1-1 …

Helianthus annuus is an invasive alien species naturalised in the central region of Argentina
where it shares an extended area with the sunflower crop. As this species has also invaded …

Invasive plants represent a valuable model system for studying contemporary evolution and
predicting evolutionary responses to global climate change. Rapid adaptation to climate …

ABSTRACT A better understanding of the genetic and ecological factors underlying
successful invasions is critical to mitigate the negative impacts of invasive species. Here, we …
