Polyamines are a class of low-molecular-weight, aliphatic nitrogen-containing bases that are widely present in prokaryotes and eukaryotes with strong biological activity. Higher plants contain mainly five polyamines: putrescine (Put), spermidine (Spd), spermine (Spm), cadaverine (Cad), and agmatine (Agm). Numerous studies indicate that polyamines serve as growth regulators in plants, participating in essential physiological processes such as growth and development, gender differentiation, fruit maturation and senescence, as well as adaptation to stress. In plants, polyamines are typically found in a free state or conjugated with hydroxycinnamic acids.
Polyamines, belonging to the class of aliphatic nitrogen-containing bases, are widely distributed in both animals and plants. The most common polyamines include putrescine (Put), cadaverine (Cad), spermidine (Spd), and spermine (Spm). Polyamines play crucial roles in cell growth and development, nucleic acid metabolism, protein synthesis, as well as metabolism of sugars, lipids, and hormones, exerting significant effects on the growth and development processes in living organisms. Therefore, the detection of polyamines is of great research significance in studying plant growth and development, as well as clinical diagnosis.
- Cellular Processes: Polyamines play essential roles in cell processes such as cell growth, differentiation, gene expression, DNA and protein synthesis.
- Physiological Processes: They are involved in organ formation, embryonic development, flower occurrence and development, leaf senescence, pollen tube growth, fruit development, and maturation.
- Participation in Various Stress Responses: Polyamines can induce the accumulation of nitric oxide (NO) and reactive oxygen species (ROS).
