Admixture between modern humans and extinct hominins has shaped the genomes of present-day individuals, but reconstructing this history has been constrained by the scarcity of archaic samples and unad...

New work explains how avocado trees coordinate a complex reproductive strategy, switching every day between male and female

In avocado and certain wild relatives in Lauraceae, a highly synchronized daily rhythm of floral sex timing promotes cross-pollination between two ...

Abstract. The suppression of recombination between sex chromosomes is a widespread feature of genetic sex determination systems. Competing explanations for

Author summary Many plants avoid self-fertilization through a system of self-incompatibility, which allows them to recognize and reject their own pollen. In plants like those in the Arabidopsis family...

Postzygotic reproductive isolation is often thought to accumulate as a byproduct of neutral divergence. Yet it frequently evolves rapidly, in line wit…

More than a century after two introduced pathogens killed billions of American chestnut trees, introgression of resistance alleles from Chinese chestnuts has contributed to the recovery of self-sustai...

In avocado and certain wild relatives in Lauraceae, pollination occurs via a synchronized rhythm of floral sex timing between two hermaphroditic flowering types. A-type plants present female-phase flo...

Chromosomal rearrangements are a major driver of evolutionary innovation, shaping processes including local adaptation, speciation, and sex chromosome evolution. Multispecies synteny datasets are rich...

Position Summary The Lowry Lab at Michigan State University is searching for a postdoctoral research associate to conduct molecular and physiological experiments to understand the causes of genetic va...

Reciprocal timing of the maturity of male and female flowers on distinct plants is a powerful outcrossing-enforcing mechanism. Two new studies reveal surprising diversity of genetic systems controllin...

In the angiosperm mating system of heterodichogamy, two hermaphroditic morphs temporally alternate between male and female flowering phases, promoting…

In most species within the walnut family, two genetically determined morphs alternate between male and female flowering phases in time. Groh et al. identify a distinct locus for this dimorphism in two...

Adaptation to different environments is thought to play a key role in speciation. However, speciation typically begins in allopatry, where reproduc...

Summary: Ancestral recombination graphs (ARGs) are a complete representation of the genetic relationships between recombining lineages and are of central importance in population genetics. Recent brea...

Biodiversity loss can occur when disturbance compromises the reproductive barriers between species, causing them to collapse into a single population through hybridization. Recent research has documen...
