  • Sulfur Assimilation in Higher Plants (With Diagram)

    2021-12-26 · Let us make an in-depth study of the sulfur assimilation in higher plants. Conversion of inorganic sulphur compounds such as SO 4 2-into sulfur-containing organic compounds such as cysteine by plants is called as sulfur or sulfate assimilation. The first step in sulfate assimilation in plants is conversion of sulfate into cysteine.
