TL;DR: The role played by various macronutrients such as nitrogen (N), sulfur (S), phosphorus (P), magnesium (Mg), calcium (Ca), and potassium (K) in plant metabolism and growth is focused on and the symptoms of deficiency and toxicity of these macronsutrients are described.

TL;DR: Concomitant decrease of the tissue thiol content after selenate treatment was consistent with the suggested role of glutathione (GSH) as a repressive effector for the expression of sulphate transporter genes.

TL;DR: It is shown that reproductive growth of wheat appears to be more sensitive to S deficiency than vegetative growth, with decreased grain size under S-limiting conditions, and breadmaking quality correlated more closely with grain S concentration than with N concentration.

TL;DR: The present paper will review the potential for biofortification of UK food crops with Se and suggest that selecting or breeding crop varieties with enhanced Se-accumulation characteristics may be possible in the longer term.

TL;DR: Mutual influences between sulfur assimilation, nitrogen imbalance, lipid breakdown, purine metabolism, and enhanced photorespiration associated with sulfur-deficiency stress are revealed in this study and may be assembled into a global scheme of metabolic regulation induced by sulfur nutritional stress, which optimizes resources for seed production.
