In vitro growth of Arabidopsis thaliana
Growth conditions - Hydroponics culture
Seeds of Arabidopsis thaliana are germinated in soil. Three weeks after sowing at 8H (100µmol/m2s) light / 16 H dark, plantlets are transferred into containers for hydroponics culture. The macronutrients composition is in mM: 1,00 Ca(NO3) 2, 1,00 MgSO4, 0,88 K2SO4, 0,25 KH2PO4, 0,01 NaCl and the micronutrients composition in µM is 20,00 FeEDTA, , 10,00 H3BO3, 1,00 ZnSO4, 1,00 MnSO4, 0,10 CuSO4, 0,01 (NH4)6Mo7O24. The pH of the solution is adjusted to 5,8 ± 0,1.

Beta vulgaris
Seeds of Beta vulgaris are germinated in soil. Three weeks after sowing, plantlets are transferred into containers for hydroponics culture.
The macronutrients composition is in mM: 2,00 Ca(NO3) 2, 1,00 MgSO4, 0,88 K2SO4, 0,25 KH2PO4 and the micronutrients composition in µM is 20 FeEDTA, 10 NaCl, 10 H3BO3, 1,00 ZnSO4, 1,00 MnSO4, 0,10 CuSO4, 0,01 (NH4)6Mo7O24. The pH of the solution is adjusted to 5,8 ± 0,1. In the Mg deficiency experiments, plants are fed with a Mg-free nutrient solution, which is the same as above formulated, except that 1,00 mM MgSO4 was replaced by 1,00 mM Na2SO4.
During all the experiment, nutrient solution are replaced every 4 days. The growth conditions in the culture room are 16 H light (300 µE m-2 s-1) / 8 H dark photoperiodism, temperature 23°C.
Thlaspi caerulescens - Thlaspi arvense
Seeds of Thlaspi are germinated on sterilized and moistened sand. After germination, the sand is moistened with 0,2-strength nutrient solution (see below). Five to seven days after germination, seedlings are transferred to 1,2 l vessels (10 plants per vessel) containing a nutrient solution (Basic "modified" 0,1 strength Hoagland's solution) which composition is in mM: 0,40 Ca(NO3) 2, 0,20 MgSO4, 0,50 KNO3, 0,10 KH2PO4 and the micronutrients composition in µM is 20 FeEDDHA, 10,00 H3BO3, 10,00 ZnSO4, 2,00 MnSO4, 0,20 CuSO4, 0,01 Na2MoO4. Plants are grown in a glasshouse with supplementary illumination provided by sodium-vapour lamps to give a photoperiod of 16 H per day.
The nutrient solution is aerated continuously and renewed every seven days.
