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 SPPS Secretary has now started to collect documents, pictures and other material for the book about the history of the Scandinavian Plant Physiology Society's, that will be published in 2012 as a celebration of the Society's 65th anniversary. While much information is available in printed or electronic form, we believe that the memories of our many members are key to a comprehensive coverage of the history of SPPS.
Maybe you overheard the discussion where the first thoughts of a Scandinavian society for plant physiologists emerged, or maybe you participated in the board meeting where it was decided to publish the journal Physiologia Plantarum? The secretary is eager to collect all kinds of information about SPPS, so if you think you can make a contribution, please don't hesitate to contact us at spps@helsinki.fi.
You can find more information about the history project in a former article of SPPS Newsletter.
