Similar traits and functions commonly evolve in nature. Here, we explore patterns of
replicated evolution across the plant kingdom and discuss the processes responsible for …

Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

Speciation is the process by which barriers to gene flow evolve between populations.
Although we now know that speciation is largely driven by natural selection, knowledge of …

Speciation is driven by the evolution of reproductive isolating barriers that reduce, and
ultimately prevent, substantial gene flow between lineages. Despite its central role in …

Studies of plants have been instrumental for revealing how new species originate. For
several decades, botanical research has complemented and, in some cases, challenged …

Gravity is one of the fundamental environmental cues that affect plant development. Indeed,
the plant architecture in the shoots and roots is modulated by gravity. Stems grow vertically …

Identifying the genetic architecture underlying adaptive traits is exceptionally challenging in
natural populations. This is because associations between traits not only mask the targets of …

Plants adapted to challenging environments offer fascinating models of evolutionary
change. Importantly, they also give information to meet our pressing need to develop …

Two major developments have made it possible to use examples of ecological radiations as
model systems to understand evolution and ecology. First, the integration of quantitative …

Understanding the genetic architecture of complex traits is a major objective in biology. The
standard approach for doing so is genome-wide association studies (GWAS), which aim to …
