Sulfur (S) is an essential nutrient for plants causing chlorosis and retard growth and development as deficiency. We performed to expand our knowledge on the metabolic perturbation of bell pepper plants in response to S deficiency. Primary metabolites from the leaves, roots and fruits and flavonoids from the leaves were investigated using GC-TOF-MS and HPLC-DAD-QTOF-MS after 15 days of S deficiency. In the leaves, carbohydrates and amino acids showed a trend of increase whereas organic acids decreased. In the roots, carbohydrate contents decreased, by contrast, amino acids and organic acids increased. In the fruits, carbohydrates and organic acids decreased. Furthermore, the levels of flavonoids in the leaves differently responded with the type of derivatives. Considering the significant increase in amino acids in the leaves and a decrease in carbohydrates in the fruits, our results suggest that C-N metabolism was likely to be affected by S deficiency. Sulfur deficiency could cause the shortage of soluble carbohydrates from source to sink tissue due to protein degradation followed by abundant amino acids in the leaves. Together, S-containing fertilizers could be used to ensure favorable crop production and quality in low fertility soils including the reclaimed land.
