Overview. Plant melatonin is an indole compound produced in plants and has a similar structure and activity to animal melatonin. Plant melatonin plays an important role in plant growth and development, antioxidant, anti-inflammatory, and anti-stress environments. Unlike animal melatonin, plant melatonin synthesis is not regulated by light, but by hormones such as auxin, ethylene, and cytosin.
2. Research status of plant melatonin.
In recent years, more and more studies have shown that plant melatonin plays an important role in plant adaptation to environmental changes, regulation of growth and development, and resistance to stress. For example, studies have found that under stress conditions such as drought, high and low temperatures, plant melatonin levels increase, which improves plant stress resistance. In addition, plant melatonin can also regulate the growth and development of plants, such as promoting seed germination, flowering, and fruit ripening.
3. Factors affecting plant melatonin.
The synthesis and release of plant melatonin is influenced by a variety of factors, including genotype, environmental factors, and hormones. Genotype is one of the important factors affecting the content of melatonin in plants, and there are differences in the content and composition of melatonin in different varieties of plants. In addition, environmental factors such as light, temperature, and humidity can also affect the synthesis and release of melatonin from plants. In addition, some hormones such as auxin, ethylene, and cytokine can also regulate the synthesis and release of plant melatonin.
Fourth, look forward to the future.
As a compound with important biological functions, plant melatonin has a wide range of application prospects in agricultural production and medicine. Future research can focus on the following aspects: 1) to deepen the synthesis and release mechanism of plant melatonin, so as to provide a theoretical basis for increasing the content of plant melatonin through genetic engineering;2) To study the interaction mechanism of plant melatonin with other hormones, and to reveal the mystery of plant growth and development and adaptation to environmental changes3) To study the application value of plant melatonin in the field of medicine, develop new drugs and solutions, and contribute to the cause of human health.
In conclusion, plant melatonin, as an important physiologically active substance, plays an important role in plant growth, development, and adaptation to environmental changes. In the future, it is necessary to strengthen the research on its synthesis, release and regulatory mechanism, so as to better use its potential to serve agricultural production, medicine and other fields.
