The excessive accumulation of cobalt (Co) in plant tissues severely impairs growth that ultimately reduces the yield. However, melatonin (MT) has been known to mediate abiotic stress tolerance plants. present study aimed at investigating protective mechanisms exogenously applied MT (0, 50 and 100 μM) under Co 100, 200 300 by focusing on morpho-physiological, biochemical cellular characterizations Brassica napus Cobalt (300 alone treatment drastically inhibited stomatal conductance, height (45%), leaf area (30%), free amino acid (139%), relative electrolyte leakage (109%), total soluble sugars (71%), compared with control. exogenous supply notably minimized oxidative damage, lipid peroxidation maintained membrane integrity Co-toxicity restricting overproduction ROS (H2O2 O2•), MDA leaves roots.

Abstract Seed germination (SG) is the first stage in a plant's life and has an immense importance sustaining crop production. Abiotic stresses reduce SG by increasing deterioration of seed quality, reducing potential, vigor. Thus, to achieve sustainable level yield, it important improve under abiotic stress conditions. Melatonin (MEL) biomolecule that interplays developmental processes regulates many adaptive responses plants, especially stresses. this review specifically summarizes discusses mechanistic basis MEL‐mediated MEL regulating some stress‐specific common responses. For instance, induced specific include regulation ionic homeostasis, hydrolysis storage proteins salinity stress, C‐repeat binding factors signaling cold starch metabolism high temperature heavy metal activation aquaporins accumulation osmolytes drought stress. On other hand, mediated gibberellins biosynthesis abscisic acid catabolism, redox Ca 2+ are amongst Nonetheless such as endogenous contents, plant species, growth conditions also influence above‐mentioned In conclusion, interacting with different physiological mechanisms.

Melatonin application has obvious improving effects on alleviating the drought-induced inhibition of plant growth. However, root phenotypic dynamics in wheat treated with melatonin remain unknown. This study was conducted using RhizoPot, a novel and improvised situ observation device, three treatments, including normal water condition (CK), drought (Ds, relative content 45–50%), 100 µM treatment under (MT). Results showed that MT effectively improves morphological indicators, (specific root) length, surface area, volume; length density; average diameter plants. Also, inhibitory effect shoot morphology, height, dry weight, net photosynthesis, stomatal aperture leaves, were improved significantly through condition. Life span percent survival fine root, lateral hair at different segments also treatment. Compared those shown CK Ds, contents leaves roots increased, expression levels melatonin-synthesis-related genes (TaCOMT TaTDC) upregulated The findings this may clarify resistance mechanism stress.

Melatonin is a potent antioxidant that can prevent plant damage caused by adverse stresses. It remains unclear whether exogenous melatonin mitigate the effects of salt stress on seed germination and seedling growth sorghum (Sorghum bicolor (L.) Moench). The aim this study was to decipher protective mechanisms (100 μmol/L) seedlings under NaCl-induced (120 mmol/L). Plant morphological, photosynthetic, physiological characteristics were analyzed at different timepoints after sowing. Results showed inhibited germination, growth, biomass accumulation reducing photosynthetic pigment contents, efficiency, root vigor, mineral uptake. In contrast, priming with enhanced biosynthesis, K+ content stress. application additionally activities enzymes (superoxide dismutase, catalase, ascorbate peroxidase, glutathione reductase) increased levels non-enzymatic antioxidants (reduced glutathione, ascorbic acid) in leaves. These changes accompanied increase leaf contents soluble sugars, proteins, proline, as well decrease hydrogen peroxide accumulation, malondialdehyde content, electrolyte leakage. Our findings indicate alleviate stress-induced through multifaceted mechanisms, such improving performance facilitating ion homeostasis osmoregulation, promoting defense reactive oxygen species scavenging.
