Research interest

Programmed cell death (PCD) has been observed in various developmental processes in plants such as tracheary element differentiation, root cap shedding, androgenesis, leaf senescence, aerenchyma formation etc. PCD also appears to play an important role in leaf development in species with perforated leaves, although almost nothing is known about this process. Therefore, I am interested in looking at whether cell death pattern during formation of perforations is a form of PCD or not. In my study Monstera obliqua and Aponogeton madagascariensis have been selected as model systems.
