Soybean seeds provide an excellent source of protein for human and livestock nutrition. However, their nutritional quality is hampered by a low concentration of the essential sulfur amino acid, methionine (Met). In order to study factors that regulate Met synthesis in soybean seeds, this study used the Met-insensitive form of Arabidopsis cystathionine(More)
The essential sulfur-containing amino acid methionine plays a vital role in plant metabolism and human nutrition. In this study, we aimed to elucidate the regulatory role of the first committed enzyme in the methionine biosynthesis pathway, cystathionine γ-synthase (CGS), on methionine accumulation in tobacco seeds. We also studied the effect of this(More)
The sulfur-containing essential amino acid methionine controls the level of important metabolites and processes in plants. In addition, methionine levels limit the nutritional quality of many crop plants. The level of methionine is regulated mainly by cystathionine γ-synthase (CGS), the first enzyme committed to its biosynthesis. Within our efforts to(More)
