Additional recruitment to the Doctoral School of Natural Sciences beyond the limit of places
Project description:
Excess nitrogen in the environment leads to serious ecological and climatic consequences. Although this element is essential for plant growth, its overuse, primarily resulting from the application of synthetic fertilizers, industrial emissions, and animal waste, leads to soil degradation and contamination of surface and groundwater. Moreover, nitrogen compounds contribute to air pollution and the formation of acid rain, further disrupting ecosystem balance. Human activity has more than doubled the natural nitrogen cycle, which significantly affects global climate change. While plants initially benefit from high nitrogen availability, its excess can disrupt their development, making them more susceptible to environmental stresses. Moderate levels of nitrogen promote root development and increase root biomass; however, an excess can induce morphological and anatomical changes, such as growth inhibition, reduced root diameter, and alterations in tissue structure, thereby limiting the transport of water and nutrients. These responses reflect a trade-off between maximizing nitrogen uptake and maintaining the functional integrity of the root system under conditions of high nutrient availability.
The aim of the project is to investigate the mechanisms regulating root growth in relation to nitrogen availability and to determine whether this relationship is modified under drought conditions. The research will be conducted on the model tree species Populus trichocarpa, using anatomical, physiological, and molecular approaches.
The research tasks include: 1/ Identification of key developmental stages of plants under varying nitrogen availability, with particular emphasis on symptoms of restricted root system growth; 2/ Identification of cytological changes in root cells in response to excess nitrogen; 3/ Characterization of the molecular and genetic mechanisms regulating root system responses to excess nitrogen; 4/ Analysis of the combined effects of excess nitrogen and varying water availability on root system functioning.
REQUIRED SKILLS OF THE CANDIDATE:
· a Master’s degree in biology, biotechnology, or a related field;
· basic knowledge of cell biology and molecular biology techniques, as well as the ability to analyze data and draw conclusions;
· proficiency in English; knowledge of Polish will be considered an additional advantage;
· commitment and motivation to engage in research work.
