The effect of the S nutritional status on a plant's capability to cope with Fe shortage was studied in solution cultivation experiments in barley (Hordeum vulgare L. cv. Europa). Barley is a Strategy II plant and responds to Fe deficiency by secretion of chelating compounds, phytosiderophores (PS). All PS are derived from nicotianamine whose precursor is(More)
The effect of iron (Fe) and sulphur (S) deprivation on sulphate uptake and assimilation pathways was investigated in durum wheat by analysing the expression of genes coding for major transporters and enzymes involved in sulphate assimilation and reduction: high-affinity sulphate transporters (TdSultr1.1 and TdSultr1.3), ATP sulphurylase (TdATPSul1 and(More)
As the salt-affected areas are expected to increase substantially in subsequent years, the impact of salinity on plant growth and yield is likely to increase. One of the first consequences of plant exposure to high saline concentrations is the formation of reactive oxygen species (ROS). In order to allow adjustment of the cellular redox state, plant(More)
