“…Milder reductions in other S-containing metabolites, including GSH, Met, Cys, SAM, SMM, and S-adenosyl-L-homocysteine (SAH) were also observed [15]. Conversely, OAS dramatically accumulated by up to 140-fold in roots on −S [15,17,37,42]. The levels of non-polar amino acids, including valine (Val), Isoleucine (Ile), leucine (Leu), phenylalanine (Phe), and tryptophan (Trp), and the polar amino acids serine (Ser), threonine (Thr), arginine (Arg), and glutamine (Gln) along with total free proteinogenic amino acids were increased in S-deprived roots [15].…”
