Outbreeding depression and breeding system evolution in small, remnant populations of Primula vulgaris: consequences for genetic rescue. [PDF]
Conserv Genet, 2018 Many species suffer from anthropogenic habitat fragmentation. The resulting small and isolated populations are more prone to extinction due to, amongst others, genetic erosion, inbreeding depression and Allee-effects.

Plant Diversity, 2016 Primula chungensis is a species with considerable floral and mating-system variation, including distylous (outcrossing), homostylous (selfing) and mixed populations that contain both outcrossing and selfing forms.

Rapid detection of RNase-based self-incompatibility in Lysimachia monelli (Primulaceae). [PDF]
Am J BotAbstract Premise Primroses famously employ a system that simultaneously expresses distyly and filters out self‐pollen. Other species in the Primulaceae family, including Lysimachia monelli (blue pimpernel), also express self‐incompatibility (SI), but involving a system with distinct features and an unknown molecular genetic basis.

Journal of Ecology, Volume 108, Issue 6, Page 2169-2183, November 2020., 2020 Heterostyly is a genetically determined floral polymorphism of style length promoting outcrossing between individuals of different morphs, which usually coexist within populations at equal frequencies. However, a nationwide citizen‐science campaign in Estonia revealed the prevalence of short‐styled individuals over long‐styled ones in a common ...

Variation and evolution of herkogamy in Exochaenium (Gentianaceae): implications for the evolution of distyly. [PDF]
Ann Bot, 2013 Backgrounds and Aims The spatial separation of stigmas and anthers (herkogamy) in flowering plants functions to reduce self-pollination and avoid interference between pollen dispersal and receipt.
