The mutualistic fungus Piriformospora indica protects barley roots from a loss of antioxidant capacity caused by the necrotrophic pathogen Fusarium culmorum [PDF]

, 2013
Fusarium culmorum causes root rot in barley (Hordeum vulgare), resulting in severely reduced plant growth and yield. Pretreatment of roots with chlamydospores of the mutualistic root-colonizing basidiomycete Piriformospora indica (Agaricomycotina ...

Changes in the ascorbate-glutathione system during storage of recalcitrant seeds of Acer saccharinum L.

Acta Societatis Botanicorum Poloniae, 2011
Two seed lots of Acer saccharinum (recalcitrant), with an initial moisture content of 50% and 55%, were stored at +3oC for 6 months. After this time, their viability (measured as germinability) reached 100% and 30%, respectively.

Neodymium improves the activity of ascorbate-glutathione cycle and chloroplast function of wheat seedlings under chromium stress

Photosynthetica, 2020
We investigated the roles of neodymium trichloride (NdCl3) in regulating ascorbate-glutathione (AsA-GSH) cycle and chloroplast function of chromium (Cr)-stressed wheat seedlings. The findings showed that Cr stress markedly increased malondialdehyde (MDA)

Exogenous silicon enhances the systemic defense of cucumber leaves and roots against CA-induced autotoxicity stress by regulating the ascorbate-glutathione cycle and photosystem II

Ecotoxicology and Environmental Safety, 2021
Cinnamic acid (CA), one of the main autotoxins secreted by cucumber roots during continuous cropping, inhibits plant growth and reduces yield. Silicon (Si) is an environmentally friendly element that alleviates abiotic stresses in plants, but the ...

Redox Homeostasis via Gene Families of Ascorbate-Glutathione Pathway

Frontiers in Environmental Science, 2015
The imposition of environmental stresses on plants brings about disturbance in their metabolism thereby negatively affecting their growth and development and leading to reduction in the productivity. One of the manifestations of abiotic and biotic stress

Physiological and Biochemical Dissection Reveals a Trade-Off between Antioxidant Capacity and Heat Tolerance in Bread Wheat (Triticum aestivum L.)

Antioxidants, 2021
Heat stress alters photosynthetic components and the antioxidant scavenging system, negatively affecting plant growth and development. Plants overcome heat stress damage through an integrated network involving enzymatic and non-enzymatic antioxidants ...

Melatonin: Awakening the Defense Mechanisms during Plant Oxidative Stress

Plants, 2020
Melatonin is a multifunctional signaling molecule that is ubiquitously distributed in different parts of a plant and responsible for stimulating several physio-chemical responses to adverse environmental conditions. In this review, we show that, although

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.
