Secondary homostyly in Primula L.; evidence for the model of the ‘S’ supergene [PDF]

New Phytologist, 1992
summaryIn Primula, in which 9% of the species are homostyle, it is estimated that 54% are polyploid, while only 4% of the cytologically examined heterostyle species are polyploid.To investigate the supposed secondary and recombinational nature of homostyly in polyploid Primulas of section Aleuritia, crosses were made between three diploid heterostyle ...

Rapid detection of RNase-based self-incompatibility in Lysimachia monelli (Primulaceae). [PDF]

Am J Bot
Abstract 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.

Landscape context and plant population size affect morph frequencies in heterostylous Primula veris—Results of a nationwide citizen‐science campaign

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 ...

Primary homostyly in Primula L. subgenus Sphondylia (Duby) Rupr. and the evolution of distyly in Primula [PDF]

New Phytologist, 1993
SUMMARYWe have studied eight species classified within Primula L. subgenus Sphondylia (Duby) Rupr. Two have monomorphic flowers and four have typically distylous flowers. P. floribunda Wall, includes both monomorphic and distylous races, while P. boveana Decres.

An Overview: Distribution, Production, and Diversity of Local Landraces of Buckwheat in Nepal

Advances in Agriculture, Volume 2017, Issue 1, 2017., 2017
Buckwheat is a sixth staple food crop after rice, wheat, maize, finger millet, and barley in Nepal. It is considered as an alternate cereal and poor man’s crop, representing an important food supply in remote places of Himalayas. It is the best crop in higher altitude in terms of adaptation to different climatic variables and easily fitted to different

The Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

TAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

Journal of Ecology, Volume 114, Issue 1, January 2026.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Mutualisms drive plant trait evolution beyond interaction‐related traits

Ecology Letters, Volume 27, Issue 2, February 2024.
This study reveals that mutualistic interactions impact traits beyond interaction‐related traits. While strong mutual dependencies appear to slow trait evolution, facultative and generalist mutualisms are associated with rapid trait change. This challenges the notion that mutualisms merely stabilise trait evolution and underscores their broader ...
