Reactive oxygen species (ROS) are important regulating factors that play a dual role in plant and human cells. As the first messenger response organisms, ROS coordinate signals growth, development, metabolic activity pathways. They also can act as an alarm mechanism, triggering cellular responses to harmful stimuli. However, excess cause oxidative stress-related damage oxidize organic substances, leading malfunctions. This review summarizes current research status mechanisms of eukaryotic cells, highlighting differences similarities between two elucidating their interactions with other reactive substances ROS.

Abstract Melatonin, the most widely distributed hormone in nature, plays important roles plants. Many physiological processes plants are linked to melatonin, including seed germination, anisotropic cell growth, and senescence. Compared with animals, different possess diverse melatonin biosynthetic pathways regulatory networks. Whereas biosynthesis animals is known be regulated by ambient signals, little about how responds environmental signals. Plants affected numerous factors, such as light, temperature, moisture, carbon dioxide, soil conditions, nutrient availability at all stages of development tissues. Melatonin content exhibits dynamic changes that affect plant growth development. various species-specific responses conditions. However, much remains learned, not factors have been studied, mechanisms which these influence biosynthesis. In this review, we provide a detailed, systematic description signaling providing reference for in-depth research on issue.

Abstract Melatonin is a highly conserved and ubiquitous molecule that operates upstream of broad array receptors in animal systems. Since melatonin was discovered plants 1995, hundreds papers have been published revealing its role plant growth, development, adaptive responses to the environment. This paper summarizes current state knowledge melatonin’s involvement regulating ion homeostasis abiotic stress tolerance. The major topics covered here are: (i) control H+-ATPase activity implication for various stresses; (ii) regulation reactive oxygen species (ROS)–Ca2+ hub by signaling; (iii) ionic via hormonal cross-talk. We also show properties allow direct scavenging ROS, thus preventing negative effects ROS-induced activation channels. above ‘desensitization’ may play critical stress-induced K+ loss from cytosol as well maintaining basic levels cytosolic Ca2+ required optimal cell operation.
