Transcriptome reveals phosphate responses
|
Microarrays are increasingly being used for global expression studies and over the last few years this has been used to build up substantial information about the plant transcriptome. Using internet-based data ressources from previous analysis on Arabidopsis thaliana, Danish researchers have dissected the complex regulatory network involved in responses to phosphate deprivation. Tom Hamborg Nielsen and co-workers from University of Copenhagen and Aalborg University evaluated the functional relationship between several transcription factors, microRNAs (miRNAs) and feedback loops that contribute to keep P-homeostasis. The authors propose a model for the complex coordinated responses to phosphate starvation, which affect all parts of the plant and include Pi-signalling miRNAs that are transported via the phloem. However, the model still lacks any sensor of P-status, since the precise role of several recent candidates for this crucial function still needs to be verified.

The next SPPS Congress will be hosted by Centre for Organelle Research at The University of Stavanger, Norway from 21-24 August 2011. The congress will be held at Stavanger Forum, a professional congress centre, which is within a short walking distance to Stavanger city centre. Stavanger is a medium-sized town on the South-West coast of Norway with beautiful fjords and mountains with easy access to major European cities.
The 2011 SPPS Congress will not only allow the presentation of cutting-edge plant science research but will also place plant science in a wider context in relation to industrial applications and innovation arenas. The combination of invited plenary talks, selected oral presentations and poster sessions promises to be of great interest and value to senior scientists as well as PhD students and postdoctoral researchers.
We look forward to welcoming you to Stavanger in August 2011.
