Primrose homostyles: A classic case of possible balancing selection revisited. [PDF]

Mol Ecol, 2023
In this issue of Molecular Ecology, Mora‐Carrera et al. (2022) revisit a case of the loss of an outcrossing system in primroses, which has been studied as an example of balancing selection in the wild since the 1940s. Molecular variants in the gene involved in the mutant self‐fertile phenotype, which is now known, help towards understanding this ...

Unveiling the Genome-Wide Consequences of Range Expansion and Mating System Transitions in Primula vulgaris. [PDF]

Genome Biol Evol
Genetic diversity is heterogeneously distributed among populations of the same species, due to the joint effects of multiple demographic processes, including range contractions and expansions, and mating systems shifts.

Genetic Causes and Genomic Consequences of Breakdown of Distyly in Linum trigynum. [PDF]

Mol Biol Evol
Distyly is an iconic floral polymorphism governed by a supergene, which promotes efficient pollen transfer and outcrossing through reciprocal differences in the position of sexual organs in flowers, often coupled with heteromorphic self-incompatibility ...

Multiple Glacial Refugia and Complex Postglacial Dynamics of <i>Primula sikkimensis</i> (Primuaceae) in the Heterogeneous Qinghai-Tibet Plateau. [PDF]

Ecol Evol
Primula sikkimensis persisted in distinct glacial refugia within the Hengduan Mountains and eastern Himalayas during the Last Glacial Maximum. Subsequent postglacial range expansions onto the Qinghai–Tibet Plateau were accompanied by secondary contact and interspecific hybridization, collectively enhancing genetic diversity and adaptive capacity. These

Heterostylous plants in an era of global change: a review on the consequences of habitat loss and fragmentation. [PDF]

AoB Plants
The widespread loss and fragmentation of habitats have caused significant declines in biodiversity. Among plants, animal-pollinated species are particularly threatened because of the negative effects of these factors on pollinators.

Asymmetrical disassortative pollination mediated by long-/short-tongued pollinators in a distylous Limonium myrianthum (Plumbaginaceae) with a short corolla tubular small flower. [PDF]

Ecol Evol
The pollination efficiency and their effects on floral morph variation of short‐tongued and long‐tongued pollinators were investigated in two Limonium myrianthum populations with short corolla tubular small flowers and considerable floral morph variation. We found that asymmetrical disassortative pollination affects floral morph variation.

Domestication During Restoration: Unintentional Selection During Eight Generations of Wild Seed Propagation Reduces Herkogamy, Dichogamy and Heterozygosity in Clarkia pulchella. [PDF]

Mol Ecol
ABSTRACT Seed production on native seed farms has increased to meet the rising demand for plant material for restoration. Although these propagation efforts are necessary for restoration, cultivating wild populations may also result in unintentional selection and elicit evolutionary changes that mimic crop domestication, essentially turning these ...

Origin and diversification of flax and their relationship with heterostyly across the range

Journal of Biogeography, Volume 48, Issue 8, Page 1994-2007, August 2021., 2021
Abstract Aim Understanding plant diversity and how different traits have shaped the current biodiversity setting across the world is one of the major challenges for evolutionary biology. In this sense, genus Linum have been broadly studied as a model of species showing heterostyly, but no studies have attempted to investigate possible correlations ...

Different molecular changes underlie the same phenotypic transition: Origins and consequences of independent shifts to homostyly within species

, 2021
The repeated transition from outcrossing to selfing is a key topic in evolutionary biology. However, the molecular basis of such shifts has been rarely examined due to lack of knowledge of the genes controlling these transitions.
