My work covers three areas:
There is something weird about plant cells: they are lacking centrosomes. This is true for all vascular plants - which is the vast majority of land plants. How then are they orchestrating cell division? In animals, centrosomes have a role in building the mitotic spindle and they are important for controlling the plane of cell division. These functions are also important for plants, so it seems reasonable to assume that some other entity (molecule, protein, structure?) has taken over the function of the centrosome.
This entity is likely the preprophase band (including its associated proteins). The preprophase band encircles the premitotic cell and outlines the future plane of cell division. We are investigating …
Humans tend to confuse left and right occasionally. Plants don’t: Arabidopsis mutants like tortifolia1 (also called, convoluta or spiral2) are always right-handed. Precisely: all tortifolia1 organs show a right-handed twist when expanded. Why? Cortical microtubules of tortifolia1 are left-handed helical on average. This suggests that the cell wallmicrofibrils are left-handed too, which may explain right-handed growth. But what exactly makes the microtubules left-handed? We are investigating this question using single-molecule and superresolution microscopy.
In many developed countries drinking water quality suffers an alarming decline. The British Geological Survey (NERC) coined this the „nitrate time bomb“, because nitrate stored underground arrives at the groundwater level with considerable delay. High nitrate in drinking waters is dangerous for newborns. But also lakes and rivers suffer from nutrient overflow, resulting in algal blooms with concurrent impact on ecology and tourism. We are working on a solution to this problem by removing excess nutrient from waste waters through fast growing water cress (Lemna) cultures. This work involves a collaboration with a local company (Aqualight, Bramsche, Germany) and a local sewage plant (also in Bramsche).
