Nitrogenous compounds such as amino acids (AAs), polyamines (PAs), and nitric oxide (NO) plays a crucial role in the plant development, growth, and signaling. Among these compounds, PAs are ubiquitous polycationic compounds, which are usually found in all living organisms, including bacteria to plants. Multifunctional PAs mainly interact with the biomolecules such as DNA or protein to strengthen the structure. However, NO is a gaseous signaling molecule, regulates several physiological functions in the plants. In recent studies, PAs found to be induce the biosynthesis of NO, but the exact mechanism remains to be deciphered. In plants, PAs and NO crosstalk regulates the different biological functions such as stress responses and hormone regulations. In light of recent findings, PAs and NO crosstalk have been an emerging topic for researchers. Overall, the nitrogen metabolism and its related compounds are a remarkable research topic, which may be biotechnologically important to develop a high-yielding and stress-resistant crops.
