Root transcriptional profile of 1103P and SO4 grapevine rootstock plants grown in presence and absence of magnesium. Root transcriptional profile of 1103P and SO4 grapevine rootstock plants grown in presence and absence of magnesium

Differences in root transcriptional profile between two grapevine rootstocks (1103P and SO4) showing different tolerance to Mg deficiency were analyzed after 4 and 14 days of growth with (+Mg) or without (-Mg). Overall design: Half part of microcuttings of 1103P and SO4, after a 2-week hydroponic grown using a dilute nutrient solution, were treated for 4 and 14 days with a new solution containing Mg (250 µM) and the other half with a solution without Mg (equivalent mole of CaSO4). Three biological replicates were obtained by three independent experiments and collecting roots after 4 and 14 days.
