Abstract

Polyamines (PAs) play a crucial role in the physiological and biochemical regulation of plant growth. These small, organic molecules, including putrescine (Put), spermidine (Spd), and spermine (Spm), are essential for various cellular processes. They interact with DNA, RNA, proteins, and membranes to affect plant growth. Polyamines are crucial for general growth and development because they play a role in cell division, differentiation, and elongation. These bioactive compounds are actively involved in germination of seeds, shoot and root growth, flowering, and reproductive growth of plants. They contribute to abiotic stress tolerance stress of plant to withstand adverse environmental conditions. Polyamines also act as signaling molecules, modulating gene expression and enzyme activities. Their crosstalk with other growth regulators modulates plant growth and physiology. They are intricately involved in cellular and molecular processes to regulate plant growth and development. Understanding their physiological and biochemical functions provides valuable insights for optimizing agricultural practices and enhancing crop yield.

Conclusion

Polyamines play integral role in plant growth regulation, impacting various physiological and biochemical processes. These bioactive compounds have the potential for field use and are also known to protect plants from a variety of biotic and abiotic challenges. Understanding their roles at the molecular level can open avenues for targeted manipulation of polyamine metabolism for crop improvement and stress tolerance.
