Biological Activity
Spermidine (4-Azaoctamethylenediamine) is a natural polyamine synthesized from putrescine and dcSAM by spermidine synthase. It is a novel autophagy inducer that negatively regulates N-methyl-d-aspartate (NMDA).
In Vitro Studies
Spermidine plays a crucial role of against abiotic stresses, such as salt, drought, heat, and salinity-alkalinity stresses in tomato, cucumber, rice.
