Engineering morphogenesis of Marchantia polymorpha gemmae
… polymorpha (Marchantia), also known as gemmae, are an attractive system for studying these interactions. Gemmae are small, have a simple disk-like shape and are resilient to environmental conditions. As such, they are well-suited for fluorescent microscopy and the collection of gene …

Determinants of gemmae output in the liverwort Lophozia ventricosa
… variation and population parameters affecting gemmae output of a boreal and arctic liverwort species, Lophozia ventricosa, were studied in Trnndelag, a boreal region of central Norway and in the arctic tundra on Svalbard. The population parameters investigated included colony size, colony shoot …

The life history of Grimmia pulvinata (Hedw.) SM. and Tetraphis pellucida Hedw. in the laboratory and in the field
… T. pellucida usually reproduces asexually by gemmae produced in a terminal cup formed by specialised leaves. Sex organs have not been reported in culture by previous workers. In the present study antheridia formed in axenic cultures where either light intensity or the concentration of mineral …

Frameworks for reprogramming early diverging land plants
… of cellular properties in germinating gemmae. I implemented high-efficiency Cas9-mediated mutagenesis in Marchantia for use in functional molecular genetics studies. Furthermore, I produced inducible systems for expression of heterologous elements by transactivation which showed …

Cell markers for air chamber development in Marchantia polymorpha
… small flat disc-like propagules, called gemmae, that develop into adult plants. Gemmae have an open mode of development, which facilitates the live observation of developmental processes. The fundamental processes underlying morphogenesis in plants are poorly understood and epidermal …

Improved plastid transformation in Marchantia polymorpha
… genetics, and asexual reproduction by means of gemmae, small disks of tissue which provide a powerful platform for live-tissue microscopy. In this thesis, tools for Marchantia plastid transformation are systematically improved by the generation of the first plastome sequence assembly for a …

Evolution of life history strategies in Lophoziaceae
… established between gemma size and the number of gemmae produced per shoot. For two of the studied species, L. ciliata and L. /ongiflora, there was a general positive relationship between spore size and proportion of germination, with bigger spores having higher germination proportions. L …

On the role of pectin methylesterases in the development of the non-vascular land plant model Marchantia polymorpha
… contributes to growth and development of gemmae and thalli, as well as resilience against infections by a filamentous pathogen. We anticipate that this research will extend our understanding of the developmental role of PMEs beyond what has traditionally been inferred from …
