About this Research Topic
Melatonin (N-acetyl-5-methoxytryptamine) was first discovered from the pineal gland of cow in 1958. Since then, melatonin has been well known for its involvement in circadian rhythms, innate and special immunity, antioxidative activity, sleep physiology, seasonal reproductive physiology, sexual behavior. Since two research groups first discovered melatonin in plants in 1995, melatonin has drawn more and more attention of plant biologists for its wide distribution and multiple in vivo roles in various plant species. To date, melatonin is an important modulator of plant development including seed germination, primary root and lateral root development, circadian rhythm, photoprotection, flowering time, seed yield, leaf senescence and fruit ripening. Moreover, melatonin is also involved in plant immunity and plant response to various abiotic stresses.
Taken together, many new data demonstrate the complex roles of melatonin in plants, and further investigations will shed light on the global involvement of melatonin in plants and underlying mechanisms.
This Research Topic will focus on the distribution, the synthesis and metabolism, and the in vivo roles of melatonin in plants. We aim to ask whether and how melatonin functions as an important regulator during plant development and plant stress responses, and how melatonin network connects with different signaling pathways. All types of articles including original research, mini review, review, method, and perspective opinion are welcomed.
