Plant material
The height Arabidopsis thaliana accessions were obtained from INRA Versailles Genomic Resource Centre VNAT collection: An-1 (96AV, Belgium), Bl-1 (42 AV, Italy), Col-0 (186AV, Poland), Cvi-0 (166AV, Cape Verde), Ge-0 (101AV, Switzerland), Mt-0 (94AV, Libya), Oy-0 (224AV, Norway) and Shahdara (Tadjikistan). Plants were grown in a growth chamber under short photoperiod (8h light/16h dark), PPFD = 150 µmol m-2 s-1, temperature 22°C/18°C and relative humidity 60%. Plants were watered every 3 days and once a week with Plant-Prod (15-10-30, N-P-K, Fertil). Fifty-five (55) days after sowing, two fully developed leaves were sampled on each rosette and instantly quenched in liquid nitrogen. Frozen samples were then frozen-dried, dry material was grinded and 5 mg of dry powder used for metabolites extraction by adding 400 µL of methanol/water (90/10) with adonitol (55 µM) as an internal standard.
