Project name: Arabidopsis thaliana

Description: The objective of this project is to identify genes that are expressed in the Arabidopsis thaliana root tip and that are early induced (or repressed) by phoshate deficiency. Seedlings were germinated and grown (for 6 days) on phosphate rich medium and transfered to either a phosphate poor medium (Pi- = 20uM Pi treatment) or a phosphate rich medium (Pi+ = 500uM, Pi = control). Fifteen and 60 minutes after transfer, the tip (~800um) of the primary root was cut under a dissecting microscope. About 100 root tips per condition were harvested and there mRNA was analysed with the use of microarrays.Overall design: 6 dye-swap - time course,treated vs untreated comparison

Data type: Transcriptome or Gene expression

Sample scope: Multiisolate
