Sulphur (S) is a part of every living cell and is a constituent of two of the 20 amino acids which form proteins. Of all the macronutrient, S is perhaps the nutrient which has attracted the most attention in soil science and plant nutrition due to its potential defensive characteristics to pests, good nutritive potentiality to crops and its relative immobility in the soil- plant system. The benefits from S fertilisation of crops can be traced to its role in protein development, to improvement of nitrogen use, etc. However, the availability of S needed for profitable crop production continues to decline. This review highlights the prominent effects of S in plants (i.e. growth retardation, alternations of photosynthesis, stomatal movement, enzymatic activities, protein synthesis, interferences with various stress conditions, membrane functioning etc.) but also includes the mechanism of uptake and translocation. Moreover, it also throws new insights, have led us to revisit the hypothesis of S chelation.

Key words: antioxidant, chelation, oxidative stress, Sulphur deficiency, Xylem transport.
