plants, but otherwise little is known about endogenous roles of D-amino acids in plants. In the studies underlying this thesis, the negative responses to D-serine and D-alanine were converted to positive effects in Arabidopsis thaliana (Arabidopsis) plants by The easiest way to obtain amino acids that are useful for agriculture is by protein hydrolysis, breaking the peptide bridges by which the various amino acids are joined together. Hydrolysis gives amino acid chains or short chain and free (single) amino acids. It is the latter that can be used most beneficially by plants.The better the hydrolysis process is, the more free amino acids and short
