Heritabilities of lateral and vertical herkogamy in Lysimachia arvensis
(Wiley, 2019-01-07)
Herkogamy, spatial separation between stigma and anthers within a flower, is important in regulating plant-mating systems. We studied phenotypic variation and heritability of herkogamy traits in Lysimachia arvensis (=Anagallis ...

Molecular approaches reveal speciation between red- and blue-flowered plants in the Mediterranean Lysimachia arvensis and L. monelli (Primulaceae)
(Linnean Society of London, 2022)
Flower colour has played a decisive role as an evolutionary force in many groups of plants by driving speciation. A well-known example of colour polymorphism is found across the Mediterranean populations of Lysimachia ...

Polimorfismo en el color floral y especiación en Lysimachia arvensis
(2019-06-19)
Uno de los caracteres que promueven la selección divergente es el polimorfismo del color que se define como la presencia en una especie de dos o más morfos de color, genéticamente determinados e interfértiles en las ...

Characterization of Nuclear Microsatellite Markers for Rumex bucephalophorus (Polygonaceae) Using 454 Sequencing
(Botanical Society of America Inc., 2015)
Premise of the study: Nuclear microsatellite markers were developed in Rumex bucephalophorus subsp. canariensis (Polygonaceae) to investigate its genetic diversity and structure. Methods and Results: Sixteen polymorphic ...

The role of lateral and vertical herkogamy in the divergence of the blue- And red-flowered lineages of Lysimachia arvensis
(Oxford University Press, 2020-06-01)
Background and Aims: Herkogamy, or anther-stigma separation, is known to reduce self-pollen deposition, but little is known about the relative efficacy of different modes or conformations of herkogamy. We assessed the ...

Uncertain pollination environment promotes the evolution of a stable mixed reproductive system in the self-incompatible Hypochaeris salzmanniana (Asteraceae)
(Oxford University Press, 2017)
Background and aims The transition from outcrossing to selfing is a repeated pattern in angiosperm diversification and according to general theory this transition should occur quickly and mixed reproductive systems should ...

Reproductive Assurance Maintains Red-Flowered Plants of Lysimachia arvensis in Mediterranean Populations Despite Inbreeding Depression
(Frontiers Media, 2020)
Flower color polymorphism, an infrequent but phylogenetically widespread condition in plants, is captivating because it can only be maintained under a few selective regimes but also because it can drive intra-morph assortative ...

Multiple pre- and postzygotic components of reproductive isolation between two co-occurring Lysimachia species
(Wiley-Blackwell, 2023)
Genetic divergence between species depends on reproductive isolation (RI) due to traits that reduce interspecific mating (prezygotic isolation) or are due to reduced hybrid fitness (postzygotic isolation). Previous research ...
