Plant jasmonic acid (JA) is a plant hormone with a variety of biological activities, which plays an important regulatory role in plants by regulating plant growth and development and stress response. In recent years, with the deepening of research on plant jasmonic acid, it has been found that it also has some new bioactive compounds, such as methyl jasmonate (meja-opda, ja-ile and 2hja, etc.). The effects of these compounds in plants vary, but all are closely related to the biological activity of jasmonic acid.
1. Methyl jasmonate (MEJA).
Methyl jasmonate is a derivative of jasmonic acid, which has similar biological activity to jasmonic acid in plants. Studies have shown that methyl jasmonate can induce disease resistance and insect resistance in plants, and improve the stress resistance of plants. At the same time, it can also promote the growth and development and reproductive process of plants, and have an important impact on plant morphogenesis and physiological metabolism.
II. 12-OPDA
12-OPDA is a precursor substance of jasmonic acid, which can be converted into jasmonic acid in plants. Studies have shown that 12-OPDA can induce disease resistance and insect resistance in plants, and improve the stress resistance of plants. At the same time, it can also promote the growth and development and reproductive process of plants, and have an important impact on plant morphogenesis and physiological metabolism.
3. Ja-ile
Ja-ile is a conjugate of jasmonic acid to isoleucine, which has similar biological activity to jasmonic acid in plants. Studies have shown that ja-ile can induce disease resistance and insect resistance in plants, and improve plant stress resistance. At the same time, it can also promote the growth and development and reproductive process of plants, and have an important impact on plant morphogenesis and physiological metabolism.
Fourth, 2HJA
2HJA is the abbreviation of dihydrojasmonic acid, which is one of the metabolites of jasmonic acid. Studies have shown that 2HJA can inhibit the growth and development process of plants, and have an important impact on plant morphogenesis and physiological metabolism. At the same time, it can also induce disease resistance and insect resistance in plants, and improve the stress resistance of plants.
5. Other bioactive compounds.
In addition to the compounds mentioned above, there are some other bioactive compounds that are closely related to the biological activity of jasmonic acid. For example, some jasmonic acid derivatives can act as signaling molecules to transmit messages in plants, regulating plant growth and development and stress responses. In addition, there are compounds that can function in plants as transporters of jasmonic acid.
6. Summary. Plant jasmonic acid and its bioactive compounds play an important regulatory role in plants. The synthesis, decomposition and transport processes of these compounds in plants are closely related to the biological activity of jasmonic acid. Through the in-depth study of these compounds, we can provide new ideas and methods for agricultural production, and promote the improvement of crop quality and high yield and stress resistance. At the same time, these compounds can also be used as an important role in drug development and contribute to the cause of human health.
