Summary: The hormone melatonin can enhance the germination potential and other physiological attributes of soybean seeds under abiotic stresses. In particular, at concentrations of 50 mu mol L-1 and 100 mu mol L-1, melatonin significantly improved the germination indices and other physiological attributes of soybean seeds.

Summary: This study investigates the effects of functionalized carbon nanoparticles (CNPs) on chili pepper plants under drought stress. The results show that CNPs can significantly improve the relative water content, chlorophyll stability index, and chlorophyll fluorescence of the leaves. The application of CNPs also leads to a significant increase in proline content by reducing abscisic acid levels in the leaves. Furthermore, CNPs enhance the activity of antioxidant enzymes under drought stress. These findings suggest that CNPs have the potential to be used as a novel agricultural technique for crop cultivation in drought conditions.

Summary: Agro-industrial wastes of Ficus carica L. and Olea europaea L. are important sources of bioactive phenolic compounds that can be used as potential bioherbicides. This study investigated the biochemical and physiological mechanisms of action of fig and olive allelochemicals on lettuce, revealing that these compounds induce oxidative stress and trigger adaptive responses in lettuce, leading to the activation of defense systems and increased antioxidant levels. The study also found a correlation between the activation of the phenylpropanoid pathway and the presence of phenolic compounds in lettuce tissues.

Summary: The aim of this study was to investigate the response mechanisms of drought stress tolerance in two melon genotypes. Drought stress led to significant effects on the drought-sensitive genotype, while the drought-resistant genotype exhibited a robust response. Antioxidant enzyme genes and activities were upregulated in the drought-resistant genotype, resulting in decreased oxidative damage and improved growth and photosynthetic functions. The findings provide insights into coping strategies for drought stress tolerance and have implications for melon breeding and molecular studies.

Summary: The development stages of Eucalyptus marginata's fruits have an impact on the fatty acid composition, phenolic, flavonoid, and tannin contents of oils. Vegetable oils extracted from mature and immature Eucalyptus marginata fruits exhibit notable antibacterial activities against various species, while only oils from immature fruits show antifungal activity against Candida parapsilosis.

Summary: The study found that exposure to soil contaminated with cadmium and copper significantly inhibited the growth and photosynthetic activity of pigeon pea plants, leading to decreased nutrient content. High metal concentrations induced oxidative stress, increased antioxidant enzyme activities, and reduced biosynthesis of secondary metabolites, which could result in a decline in the medicinal properties of pigeon pea.

Summary: This study reveals the potential role of melatonin (MEL) in enhancing Cr stress tolerance in pepper seedlings. MEL supplementation significantly mitigated the phytotoxic effects of Cr on root morphology, gas exchange elements, and leaf photosynthetic capacity, and restored the growth of pepper seedlings.

Summary: Melatonin treatment through seed priming and foliar application improved the growth, physiological, and biochemical traits of pearl millet under drought stress. It regulated the expression of antioxidant-responsive genes, increased proline content, and reduced oxidative damage. The activities of antioxidant enzymes were also enhanced. Seed priming at 120 mu M and foliar application at 160 mu M were particularly effective.

Summary: The SlBAG9 gene in tomato is highly expressed under high-temperature conditions, with its promoter containing various stress and hormone response elements, particularly related to heat stress. Overexpression of SlBAG9 in tomato results in increased sensitivity to heat stress, leading to leaf burning, chlorophyll degradation, and reduced photosynthetic rates. Additionally, SlBAG9-overexpressing lines exhibit higher levels of lipid peroxidation and H2O2, along with lower activities of antioxidant enzymes, suggesting that SlBAG9 plays a negative role in thermotolerance by inhibiting the antioxidant defense system.

Summary: Melatonin protects plants from heavy metal stress by immobilizing the metals in cell walls and storing them in root cell vacuoles, reducing their translocation to shoots. It enhances osmolyte production, increases antioxidant enzyme activity, and improves photosynthesis, thereby improving cellular functions. Understanding melatonin-mediated response and signaling is important for sustaining crop production in heavy metal-stressed soils.

Summary: The study demonstrated that Halimione portulacoides actively responded to higher concentrations of Ce, with the shoots showing decreased antioxidant enzyme activity at 1200 μg/L. High Ce concentrations led to a loss of turgor pressure and oxidative stress in the shoots, posing a threat to the sustainability of halophytes and estuarine marshes.
