… ; (c) the agents of selection underlying local adaptation, when field experiments are paired
with environmental manipulations; (d) the processes that constrain local adaptation; and (e) …

A fundamental goal in plant biology is to identify and understand the variation underlying
plants’ adaptation to their environment. Climate change has given new urgency to this goal, as …

Transposable elements (TEs) are responsible for significant genomic variation in plants.
Our understanding of the evolutionary forces shaping TE polymorphism has lagged behind …

… e–h, Predicted structure of optimized hp-sgRNA spacers (hairpin 1 (e), hairpin 3 (f), hairpin
1 (g), hairpin 4 (h)); arrows indicate 3′ end of RNA. The sequences of the sgRNA variants …

CRISPR-associated endonuclease Cas9 cuts DNA at variable target sites designated by a
Cas9-bound RNA molecule. Cas9's ability to be directed by single ‘guide RNA’ molecules to …

… orientalis (4,000) but much smaller than the N e of the highly outcrossing C. grandiflora (…
that the N e of the founding population may be as large as 40,000. The reductions in N e in C. …

Life-history traits controlling the duration and timing of developmental phases in the life
cycle jointly determine fitness. Therefore, life-history traits studied in isolation provide an …

The extent that both positive and negative selection vary across different portions of plant
genomes remains poorly understood. Here, we sequence whole genomes of 13 Capsella …

Understanding the evolutionary forces that shape genetic variation within species has long
been a goal of evolutionary biology. Integrating data for the genetic architecture of traits from …

… As might be expected from its large effective population size (N e ) and relative lack of
population structure, purifying and positive selection are prevalent in C. grandiflora (4, 27), making …
