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.

Registration for the 6th SPPS PhD Student Conference is now closed. The Conference will be held from 2nd to 5th September in Espoo, Finland. The number of participants in the student meetings has been increasing year by year and this time almost 100 participants have registered to the conference. This means, that the upcoming conference will be the biggest ever. Forty-five percent of the participants come from Finland, 20% from Denmark, 15 % Sweden and the rest from all over the word. There will be nine sessions and every participant will be expected to present either a talk or a poster.
The session topics and confirmed plenary speakers are listed below: - Environment: Christine Foyer (UK)
- Ecophysiology: Gareth Jenkins (UK)
- Environmental Stress Responses: Maria Israelsson-Nordström (SE)
- Bioenergy: Eva-Mari Aro (FI)
- Bioinformatics: Ken Birnbaum (US)
- Biotechnology: Kirsi-Marja Oksman-Caldentey (FI)
- Signalling: Elena Baena-Gonzalez (PR)
- Development: Thomas Laux (D)
- Applied Plant Biology: CropDesign (BE)
In addition, there will be two special sessions: "Life after a PhD" - a panel discussion where invited speakers will be asked to give a talk - and "How to get published" - a discussion lead by Vaughan Hurry, editor-in-chief, from Physiologia Plantarum.
