Problem:
• Arbuscular mycorrhiza is a very common symbiosis between fungi of the phylum Glomeromycotina and land plants, which increases the supply of nutrients and the water absorption of the plant.
• In previous experiments it could be shown that the rate of establishment of arbuscular mycorrhiza and the colonization strength vary depending on the maize genotype.
• To understand the molecular basis for this genotype-dependent variation, a panel of maize lines will now be characterized in detail.
• Based on previous results, the relationship between the beginning, development and strength of colonization to measurable growth parameters is particularly interesting.
• This experiment lays the foundation for subsequently identifying the underlying genetic elements in maize and making them available for maize breeding.
Your task:
• Planning and implementation of a large greenhouse experiment
• Phenotypic characterization by measuring growth parameters
• Fluorescence-based photosynthesis measurements
• Quantitative analysis of the architecture of root systems using image analysis of root scans
• Quantification of root colonization by AM fungi using microscopy
• Evaluation and statistical analysis of the collected data with R
Conditions:
• Start possible from March 2020 (last possible start date July 2020)
• Possibility to combine the master thesis with a research internship
