Evolutionary history and patterns of geographical variation, fertility, and hybridization in Stuckenia (Potamogetonaceae)

Autor: Judith Fehrer, Michaela Nagy Nejedlá, C. Barre Hellquist, Alexander A. Bobrov, Zdenek Kaplan

Publikováno v: Frontiers in Plant Science, Vol 13 (2022)

Aquatic plant species are often widespread, even across continents. They pose a challenge to species delimitation and taxonomy due to their reduced morphology and high phenotypic plasticity. These difficulties are even more pronounced in the case of

A Multigene Phylogeny of Native American Hawkweeds (Hieracium Subgen. Chionoracium, Cichorieae, Asteraceae): Origin, Speciation Patterns, and Migration Routes

Autor: Judith Fehrer, Yann J. K. Bertrand, Matthias Hartmann, Petra Caklová, Jiřina Josefiová, Siegfried Bräutigam, Jindřich Chrtek

Publikováno v: Plants, Vol 11, Iss 19, p 2584 (2022)

Native American hawkweeds are mainly mountainous species that are distributed all over the New World. They are severely understudied with respect to their origin, colonization of the vast distribution area, and species relationships. Here, we attempt

Molecular Evolution and Organization of Ribosomal DNA in the Hawkweed Tribe Hieraciinae (Cichorieae, Asteraceae)

Autor: Judith Fehrer, Renáta Slavíková, Ladislava Paštová, Jiřina Josefiová, Patrik Mráz, Jindřich Chrtek, Yann J. K. Bertrand

Publikováno v: Frontiers in Plant Science, Vol 12 (2021)

Molecular evolution of ribosomal DNA can be highly dynamic. Hundreds to thousands of copies in the genome are subject to concerted evolution, which homogenizes sequence variants to different degrees. If well homogenized, sequences are suitable for ph

Characterization and Dynamics of Repeatomes in Closely Related Species of Hieracium (Asteraceae) and Their Synthetic and Apomictic Hybrids

Autor: Danijela Zagorski, Matthias Hartmann, Yann J. K. Bertrand, Ladislava Paštová, Renata Slavíková, Jiřina Josefiová, Judith Fehrer

Publikováno v: Frontiers in Plant Science, Vol 11 (2020)

The repetitive content of the plant genome (repeatome) often represents its largest fraction and is frequently correlated with its size. Transposable elements (TEs), the main component of the repeatome, are an important driver in the genome diversifi

The endangered Florida pondweed (Potamogeton floridanus) is a hybrid: Why we need to understand biodiversity thoroughly.

Autor: Zdeněk Kaplan, Judith Fehrer, Veronika Bambasová, C Barre Hellquist

Publikováno v: PLoS ONE, Vol 13, Iss 4, p e0195241 (2018)

Thorough understanding of biodiversity is a fundamental prerequisite for biological research. A lack of taxonomic knowledge and species misidentifications are particularly critical for conservation. Here we present an example of Potamogeton floridanu
