Objectives	to characterize the proteome from Arabidopsis ecotypes selected for contrasted responses to environmental conditions
Strategy	screening of a collection of 76 accessions for changes in root system architecture under phosphate starvation (Chevalier et al., 2003;  pdf)
	root proteome analysis by two-dimensional gel electrophoresis and MALDI-TOF MS, hierarchical clustering of data (Chevalier et al., 2004;  pdf)
Results	annotated 2D maps of root proteins from 8 Arabidopsis ecotypes
	- 2 very close accessions (Col 0, Col 4) showing the classical double response to phosphate starvation (decrease in both lenght of primary root and number of lateral roots)	Col 0 Col 4
	- 3 widely-used accessions (Cvi 0, Ler 1, Ws 1) showing also the classical double response	Cvi0 Ler 1 Ws 1
	- and 3 accessions (Be 0, Ll 0, Rld 1) showing only one of the two responses	Be 0 LI 0 Rld 1
	classification of proteomes according to protein maps and functions
