Physiological Performance of a Coastal Marsh Plant Hydrocotyle vulgaris in Natural Conditions in Relation to Mineral Nutrition and Mycorrhizal Symbio…
2020
Abstract Fluctuating soil salinity and competition for light are the main factors affecting plant distribution and performance in coastal salt marshes. The aim of the present study was to assess plant performance by means of non-destructive instrumental methods in a highly heterogeneous natural habitat. More specifically, environmental factors affecting growth and physiological performance of a clonal plant Hydrocotyle vulgaris L. were investigated. Changes in soil salinity, soil mineral characteristics, leaf nutrient concentrations, morphological parameters, chlorophyll fluorescence, and mycorrhizal symbiosis were analysed in different experimental plots of naturally growing H. vulgaris pl…
Genetic Diversity and Structure of Northern Populations of the Declining Coastal Plant Eryngium maritimum
2019
Abstract Genetic diversity among 13 northern populations of the declining coastal plant Eryngium maritimum L. at the northernmost extent of the species distribution range was studied using retro-transposon-based SSAP molecular markers. Diversity indices varied extensively among populations; some showing extremely low diversity whereas other populations exhibited moderate amounts of genetic variation. Differentiation among populations was highly variable as well. Interestingly, differentiation among northern populations was not influenced strongly by geographic distance. Closely situated populations were often more divergent than more distant populations suggesting other factors may be respo…
Genetically modified seeds and plant propagating material in Europe: potential routes of entrance and current status
2019
Genetically modified organisms (GMO), mainly crop plants, are increasingly grown worldwide leading to large trade volumes of living seeds and other plant material both for cultivation and for food and animal feed. Even though all the traded GMOs have been assessed for their safety with regards to human and animal health and the environment, there still are some concerns regarding the potential uncontrolled release in the environment of authorized or unauthorized GM plants. In this review, we identify the possible entrance routes of GM seeds and other propagating plant material in the EU which could be linked to unauthorized release of GMOs in the environment. In addition, we discuss the sit…
