Scholarcy highlights

  • Deficiency of sulphur has been recognised as a limiting factor for crop production in many regions in the world
  • Incidence of S deficiency has increasingly been reported in Brassica and cereal crops in Western Europe over the last decade, mainly as a consequence of a massive decrease of atmospheric S inputs
  • The S requirement of wheat is about 15–20 kg/ha for optimum growth
  • Reproductive growth of wheat appears to be more sensitive to S deficiency than vegetative growth, with decreased grain size under S-limiting conditions
  • Recent progress in cloning genes encoding components involved in sulphate uptake and assimilation has substantially increased our understanding of plant S nutrition and its regulation, and opened up opportunities for manipulation of S uptake and metabolism in plants
