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

Host: László Bakó

Room: Lilla hörsalen KB3A9


Abstract:

A chromatin perspective of cell cycle and genome replication during Arabidopsis organogenesis
Crisanto Gutierrez
Centro de Biologia Molecular Severo Ochoa (CSIC-UAM)
 
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.

Title Parenting for plants: a manual for the successful control of progeny seed behaviour for mothers


Host: Maria Eriksson
Place: Lilla hörsalen, KB3A9

Abstract:
 
In humans we understand that fitness is about more than just progeny yield, but also about parental optimisation of progeny behaviour. But what about plants where little is known about the influence of parents on progeny attributes beyond a shared genetic heritage? In this talk I will discuss how dynamic environmental signalling processes in the mother plant are used to generate trans-generational information flows that control offspring behaviour and permit coordination of plant life history by seasonal cues. I will show that seasonal detection pathways converging on Flowering Locus T play a key role in this process and in so doing reveal why flowering time control is important for plant fitness.

Title: Living on the edge: Responses of an evolutionarily co-evolved and a naïve
pine host in the face of mountain pine beetle range expansion


Host. Ulrika Ganeteg

Room: Lilla hörsalen, KB3A9

Abstract:
The current epidemic of mountain pine beetle (MPB) has impacted more than
28 million hectares of pine forests in western North America.  Lodgepole
pine, with a range overlapping that of MPB, has been the main species of
pine affected by the present outbreak.  From its historic range in British
Columbia, MPB has spread across the Rocky Mountains into northern Alberta.
In this novel habitat, lodgepole pine hybridizes with jack pine, a boreal
forest species.  We used species-distinguishing markers to refine this
hybrid zone, and demonstrate that MPB has undergone host range expansion
to pure jack pine.  We are testing the hypotheses that (1) host quality
differs between lodgepole and jack pine and (2) that abiotic stresses such
as water limitation affect these responses.  Lesion development following
inoculation with the MPB fungal associate Grosmannia clavigera was slower
in jack pine than lodgepole pine, with water deficit delaying lesion
development in both species.  G. clavigera inoculation significantly
increased levels of jasmonic acid in both species.  Microarray analyses
revealed that thousands of genes are invoked in the response of these pine
species to G. clavigera infection, that there are substantial differences
in responses of lodgepole and jack pine, and that water limitation alters
this transcriptional programme.

Title:
The many layers of plant hormone interactions: from metabolic networks to translation regulation

Host: Karin Ljung

Room: NOTE! Stora hörsalen KB3B1

Abstract:
Fine-tuning of the growth and development programs with the changes in the environment is a process of critical importance for plants that, due to their sessile lifestyle, cannot escape adverse environmental conditions. Plant hormones play a key role in the integration of signals triggered by endogenous and exogenous stimuli. To dissect the involvement of plant hormones in signal integration, the interaction between ethylene and auxin in the regulation of a highly plastic phenotype, root elongation, was chosen as a model. Our initial studies have uncovered an unexpected role of ethylene in the precise spatiotemporal regulation of auxin biosynthesis. Current work using genome-wide ribosome footprinting is uncovering the molecular mechanisms linking this hormone perception to the activation of a novel gene-specific translational control mechanism. Characterization of one of the targets of this translational regulation indicates that the signaling molecule EIN2 and the nonsense-mediated decay proteins UPFs play a central role in this ethylene-induced translational response. Our findings represent a new mechanistic paradigm of gene-specific regulation of translation in response to a key growth regulator in plants.
