Title:
Biogenesis and Biomedical Utilization of the Photosynthetic Apparatus

Host: Christiane Funk

Room: KB3A9, Lilla hörsalen KBC

Abstract:
Cyanobacteria, algae and plants can convert light energy to chemical energy using a very similar type of photosynthetic membrane system, named thylakoids. Current molecular analyses suggest that the initial steps of the biogenesis of the cyanobacterial energy conversion system, in particular photosystem (PS) II, progress in a membrane subfraction representing a biosynthetic center which is marked by the PS II assembly factor PratA. This factor binds and delivers manganese (Mn) to PS II and, consequently, is involved in the assembly of its oxygen evolving Mn4CaO5 cluster.
Also in chloroplasts of the eukaryotic alga Chlamydomonas reinhardtii, PSII biogenesis centres – so called translation (T) zones – have been described. We have recently identified the DLA2 factor which appears to target the chloroplast psbA mRNA to these T-zones. Interestingly, DLA2 represents the E2 subunit of the plastid pyruvate dehydrogenase enzyme suggesting a crosstalk between gene expression and carbon metabolism via this protein.
In an applied approach, the oxygen evolving activity of PSII is used to provide a constant source of oxygen supply to engineered mammalian skin tissues which usually suffer from hypoxia due to poor vascularization. In particular, our data suggest that bioartificial scaffolds can be loaded with the microalgae Chlamydomonas reinhardtii, showing high biocompatibility and photosynthetic activity in vitro. The results of this study represent a first step towards the establishment of engineered autotrophic tissues and suggest that the use of photosynthetic cells can overcome a broader spectrum of hypoxic stress conditions.

A chromatin perspective of cell cycle and genome replication during Arabidopsis organogenesis

The cell cycle is defined by a series of complex events, finely coordinated through hormonal, developmental and environmental signals, which occur in a unidirectional manner and end up in producing two daughter cells. Accumulating evidence reveals that chromatin is not a static entity throughout the cell cycle. In fact, there are many changes. It is possible to correlate the occurrence of several of these chromatin-related events with specific processes necessary for cell cycle progression. Therefore, an emerging view is that chromatin dynamics must be considered as an intrinsic part of cell cycle regulation. In this talk, I will briefly review the results supporting a chromatin perspective of the cell cycle. Also I will focus on events related to genome replication and cell division control in the meristems linked to chromatin dynamics.
