Influence of salicylic acid on phytochelatin synthesis in Zea mays during Cd stress [PDF]

, 2013
: Presoaking maize (Zea mays) seeds in salicylic acid (SA) reduces damage caused by cadmium. In the present work the possible role of phytochelatins (PCs) in SA-mediated protection against Cd toxicity was investigated. Seeds were presoaked in 0.5 mM SA,

Biosynthesis of Kaitocephalin: A Neuroprotective Natural Product Featuring a Peptide‐Like yet Nonpeptidic Scaffold

Angewandte Chemie, EarlyView.
Kaitocephalin (KCP) is a neuroprotective fungal metabolite with a unique scaffold of amino acids linked via C–C bonds. Genome‐transcriptome analyses identified its biosynthetic gene cluster (kpb cluster) in Eupenicillium shearii. LC‐MS/MS profiling identified four new KCP‐related compounds.

Exogenous Melatonin Delays Dark-Induced Grape Leaf Senescence by Regulation of Antioxidant System and Senescence Associated Genes (SAGs)

Plants, 2019
Leaf senescence is a developmentally programmed and degenerative process which comprises the last stage of the life cycle of leaves. In order to understand the melatonin effect on grapevine leaf senescence, the dark treatment on detached leaves of Vitis ...

Effect of Thallium(I) on Growth, Nutrient Absorption, Photosynthetic Pigments, and Antioxidant Response of Dittrichia Plants

Antioxidants, 2023
Dittrichia plants were exposed to thallium (Tl) stress (10, 50, and 100 µM) for 7 days. The Tl toxicity altered the absorption and accumulation of other nutrients.

Exogenous Allantoin Confers Rapeseed (Brassica campestris) Tolerance to Simulated Drought by Improving Antioxidant Metabolism and Physiology

Antioxidants, 2023
Allantoin is an emerging plant metabolite, but its role in conferring drought-induced oxidative stress is still elusive. Therefore, an experiment was devised to explore the role of allantoin (0.5 and 1.0 mM; foliar spray) in rapeseed (Brassica campestris

Effect of arsenic-phosphorus interaction on arsenic-induced oxidative stress in chickpea plants [PDF]

, 2009
Arsenic-induced oxidative stress in chickpea was investigated under glasshouse conditions in response to application of arsenic and phosphorus. Three levels of arsenic (0, 30 and 60 mg kg−1) and four levels of P (50, 100, 200, and 400 mg kg−1) were ...

Enzyme protection systems of erythrocytes in conditions of ascorbate recirculation and oxidative loading

Regulatory Mechanisms in Biosystems, 2018
Vitamin C was shown to partially protect red blood cells from oxidative changes during storage by noticeable reduction of mechanical fragility and hemolysis. In order to maintain the content of ascorbate in the reconstituted form in plasma, the latter is
