AB Treeworkers: Expert Tree Care and Biological Services for Sustainable Ecosystems
The Laboratory of Cell Biology explores selected molecular regulatory modules of plant cell polarity and morphogenesis operating mostly at the plasma membrane, at the interface of secretory pathway, membrane lipids and cytoskeleton. Plant morphogenesis is based essentially on two processes - oriented cell division and differential cell growth. As model plants we use angiosperm Arabidopsis and tobacco along with moss Physcomitrella patens. We focus on intracellular molecular mechanisms driving cellular morphogenesis such as exocytosis. Proteins participating in these mechanisms are, despite major differences in cell structure and behaviour, often very similar to those found in the fungal and animal kingdoms. The laboratory is centered around the detailed characterization and regulation of the plant vesicle tethering complex exocyst in various cell types across plant species, including plant-pathogen interactions. A significant aspect of the research is understanding of minor membrane lipids in the maintenance and establishment of cell polarity
Nutrient Uptake:
Trees rely on healthy soil with proper nutrient levels to support growth and sustain biological functions. The uptake of essential nutrients like nitrogen, phosphorus, and potassium through roots supports the tree's metabolic processes and development.
Water Management:
Proper hydration is crucial for tree health. Trees absorb water from the soil, which is necessary for photosynthesis and maintaining cell structure. Overwatering or drought can stress trees, making them susceptible to diseases.
Photosynthesis Efficiency:
Trees convert sunlight into energy through photosynthesis. Healthy leaves ensure efficient energy production, fueling growth and maintaining vigor.
Disease Resistance: Healthy trees have stronger immune responses to pathogens. Factors like fungal infections, bacterial diseases, and pest infestations can significantly impact a tree's health. Preventive care and early treatment, often biological in nature, help in managing these threats.
Structural Integrity: Trees with good biological health have strong trunks and branches, which are less prone to breakage. This resilience is essential for withstanding environmental stresses such as wind or storms.
Symbiotic Relationships: Trees often form symbiotic relationships with fungi and bacteria (e.g., mycorrhizae), which aid in nutrient absorption and enhance the tree's growth and health.
