Plants in space

Microgravity seems to impose stress on the photosynthetic apparatus according to a new American study. Seeds of rape, Brassica rapa, were germinated in growth chambers on board a space shuttle that during 14 days flight took several loops around Earth in microgravity. Growth conditions were monitored and replicated to control plants grown at the Kennedy Space Center. Microgravity did not seem to influence growth and biomass accumulation, but the chlorophyll a/b ratio increased from 2.4 in ground controls to 3.5 in space grown plants. Mainly photosystem I was affected, having a reduced number of complexes and a 30% decrease of photochemical activity. Microgravity also led to altered chloroplast ultrastructure as shown by transmission electron micrographs.

A Troedsson symposium on "Intracellular Trafficking and Cell Wall Formation in Plants" will take place at Umeå Plant Science Centre, Sweden 4-5 February 2005. The symposium is organized by the SSF (Stiftelsen för Strategisk Forskning, i.e. Swedish Foundation for Strategic Research) funded Centre of Excellence in Plant Developmental Biology.
The registration fee is covered by SSF but attendants must arrange for transportation and accommodation at hotel or youth hostel in the city at their own expenses. The deadline for registration is 30 November 2004 so everybody interested should hurry up, as the number of participants is limited to 100.
The invited speakers are:- Sebastian Bednarek, Madison, Wisconsin, USA
- Paul Dupree, Cambridge, UK
- Elzbieta Glaser, Stockholm, Sweden
- Gerd Jürgens, Tübingen, Germany
- Paul Knox, Leeds, UK
- Sybille Kubis, Leicester, UK
- Ian Moore, Oxford, UK
- Wolf-Dieter Reiter, Connecticut, USA
- Henrik Scheller, Copenhagen, Denmark
For more information, registration and submission of the abstract visit the symposiums website or contact the secretariat by e-mail.
