The main focus of the research carried out in the lab is on the hormonal control of late stamen development in the model species Arabidopsis thaliana. Late stamen development consists of three simultaneous developmental processes: pollen maturation, anther dehiscence and filament elongation. We have demonstrated that auxin peaks during the initial stage of late development and that subsequently its concentration declines. The auxin peak is responsible for promoting filament elongation, whereas the subsequent decrease in auxin concentration triggers pollen maturation and anther dehiscence. As jasmonic acid (JA) controls positively anther dehiscence, we are currently investigating the interaction of auxin with jasmonic acid to control the anther dehiscence process. The ultimate goal is to understand how the cross talk between different hormones regulates late stamen development. The other research line in the lab focuses on the mechanisms of tolerance and accumulation of heavy metals and arsenic (As) in model species and in hyperaccumulators, that can be used to remediate contaminated soils. The role of phytochelatins (PCs) in heavy metal tolerance has been investigated in Arabidopsis and tobacco plants. We are currently investigating the involvement of the ABC transporter MRP3 in the compartmentalization of As- PCs and complexes into the vacuole. |
