Patterns of genomic variation reveal a single evolutionary origin of the wild allotetraploid Mimulus sookensis

This study identifies a single evolutionary origin of the wild allotetraploid Mimulus sookensis using genomic data, estimating its origin to be around 71,000 years ago.

Strong postmating reproductive isolation in Mimulus section Eunanus

The paper examines postmating reproductive isolation and genetic divergence in Mimulus species, finding strong barriers preventing hybridization despite historical gene flow.

Developmental evidence for parental conflict in driving Mimulus species barriers

The paper investigates parental conflict in Mimulus species by analyzing hybrid seed inviability and identifies the chalazal haustorium as a target of conflict affecting resource allocation.

Evolution of multiple postzygotic barriers between species in the Mimulus tilingii species complex

This study identifies strong postzygotic reproductive barriers between three closely related Mimulus species, suggesting geographic isolation played a key role in their speciation.

Genome-wide misexpression associated with hybrid sterility in Mimulus (monkeyflower)

This study identifies genome-wide misexpression in sterile hybrids of Mimulus species, showing it is a downstream effect of sterility rather than a cause.

A two-locus hybrid incompatibility is widespread, polymorphic, and active in natural populations of Mimulus

The paper identifies a two-locus hybrid incompatibility system in Mimulus species, showing it is widespread, polymorphic, and subject to natural selection.

Gene duplicates cause hybrid lethality between sympatric species of Mimulus

The paper identifies a gene duplication causing hybrid lethality in Mimulus species hybrids due to misregulated photosynthetic gene expression.

Mechanisms of transmission ratio distortion at hybrid sterility loci within and between Mimulus species

The paper investigates transmission ratio distortion at hybrid sterility loci in Mimulus species, finding hybrid transmission bias and a genetically independent hybrid lethality system.
