NETWORKING FOR DIVERSITY Annual Report 2017 – 2019 2017 – BGBM BGBM Annual Report 2017 – 2019 Cover image: Research into global biodiversity and its significance for humanity is impossible without networks. The topic of networking can be understood in different ways: in the natural world, with the life processes within an organism – visible in the network of the veins of a leaf or in the genetic diversity in populations of plants – networking takes place by means of pollen, via pollinators or the wind. In the world of research, individual objects, such as a particular plant, are networked with the data obtained from them. Networking is also crucial if this data is to be effective as a knowledge base for solving global issues of the future: collaboration between scientific experts within and across disciplines and with stakeholders at regional, national and international level.

Florian Wagner iv Abstract Plant systematics, the study of taxonomy, phylogeny and evolutionary processes in plants has undergone considerable progress in the last decades. The application of modern molecular approaches and DNA-sequencing techniques in the field has led to an improved inventory of biodiversity and a better understanding of evolutionary processes shaping the biological diversity on our planet. The increased availability of molecular and genomic data has particularly facilitated the investigation of shallowly diverged and taxonomically complex taxon-groups, which is challenging due to minor morphological differences, low genetic differentiation and/or hybridization among taxa. The present thesis investigates species delimitation, hybridization and polyploidization in the recently diverged genera Leucanthemum Mill. and Rhodanthemum B.H. Wilcox & al. of the subtribe Leucantheminae K.Bremer & Humphries (Compositae, Anthemideae) by applying Sanger-, 454-pyro-, and restriction site associated

A noxious weed is defined as “any plant or plant product that can directly or indirectly injure or cause damage to crops (including nursery stock or plant products), livestock, poultry, or other interests of agriculture, irrigation, navigation, the natural resources of the United States, the public health, or the environment” (7 U.S.C. § 7701-7786, 2000). We use the PPQ weed risk assessment (WRA) process (PPQ, 2015) to evaluate the risk potential of plants, including those newly detected in the United States, those proposed for import, and those emerging as weeds elsewhere in the world. The PPQ WRA process includes three analytical components that together describe the risk profile of a plant species (risk potential, uncertainty, and geographic potential; PPQ, 2015). At the core of the process is the predictive risk model that evaluates the baseline invasive/weed potential of a plant species using information related to its ability to establish, spread, and cause harm in natural, anthropogenic, and production systems (Koop et al., 2012).

Here we present an overview on the results of eight years of research line devoted to the organisation, expression and evolution of rRNA genes in plant genomes. We describe how we discovered a new rDNA arrangement in genus Artemisia, which includes all rRNA genes in a single unit (L-type). This was the first time that such organisation was found in seed plants. We further explored family Asteraceae in depth, to which Artemisia belongs, to find that the L-type arrangement may be present in about 25% of its species. Later on we move to gymnosperms to describe the landscape of rRNA arrangements in a representative sample of its diversity. We assess the expression rate of the L-type rRNA in several L-type species, which is comparable to that of species with separated arrangement of rRNA genes (S-type). Finally, we present the resource www.plantrdnadatabase.com which includes information on type of rDNA arrangement, number and position of rDNA loci in plants.

We devel- oped a preliminary determination of plants that pose the greatest risk of becoming invasive in California, primarily through the horticultural industry. We identified 774 species that are invasive elsewhere in Mediterranean climates but not yet invasive in California. From this list, we determined which species are sold through the horticulture industry, whether they are Giant reed (Arundo donax) infesting a wetland area in Southern California. Giant reed was introduced as both an ornamental and erosion control species and is now one of the most invasive species in sold in California and whether they have the state. been reported as naturalized in California.
