Arabidopsis thaliana dehydroascorbate reductase 2 : conformational flexibility during catalysis [PDF]

, 2017
Dehydroascorbate reductase (DHAR) catalyzes the glutathione (GSH)-dependent reduction of dehydroascorbate and plays a direct role in regenerating ascorbic acid, an essential plant antioxidant vital for defense against oxidative stress.

Identification, characterization, and expression of Oryza sativa tryptophan decarboxylase genes associated with fluroxypyr‐meptyl metabolism

The Plant Genome, Volume 18, Issue 1, March 2025.
Abstract Tryptophan decarboxylase (TDC) belongs to a family of aromatic amino acid decarboxylases and catalyzes the conversion of tryptophan to tryptamine. It is the enzyme involved in the first step of melatonin (MT) biosynthesis and mediates several key functions in abiotic stress tolerance.

Improving photosynthesis and the ascorbate-glutathione cycle of own-root and grafted-root chrysanthemums by brassinolide under drought stress

Horticultural Science
Many studies have demonstrated that brassinolide improves the drought tolerance of plants. This study aims to test whether the drought tolerance of chrysanthemums can be improved by brassinolide and to clarify the underlying physiological mechanism.

Effects of chlorogenic acid on capacity of free radicals scavenging and proteomic changes in postharvest fruit of nectarine.

PLoS ONE, 2017
To study how chlorogenic acid affects changes of reactive oxygen species (ROS) and the proteins involved in ROS scavenging of nectarine during storage time, the fruits were treated with chlorogenic acid (CHA) then stored at 25°C for further studies.

Tolerance to combined drought and heat stress in edamame is associated with enhanced antioxidative responses and cell wall modifications

Physiologia Plantarum, Volume 177, Issue 2, March/April 2025.
Abstract Drought and heat stress often co‐occur in nature, and their combined effects are a major driver of crop losses, causing more severe damage to plant metabolism than when they occur individually. This study investigates the responses of three edamame cultivars (AGS429, UVE14, and UVE17) to combined drought and heat (DH) stress, with emphasis on ...

Expression in grasses of multiple transgenes for degradation of munitions compounds on live fire training ranges [PDF]

, 2016
The deposition of toxic munitions compounds, such as hexahydro-1, 3, 5-trinitro-1, 3, 5-triazine (RDX), on soils around targets in live-fire training ranges is an important source of groundwater contamination.

Antioxidant activity as a response to cadmium pollution in three durum wheat genotypes differing in salt-tolerance

Open Chemistry, 2020
Durum wheat is commonly used in various food industry industries and cultivated worldwide. A serious problem with the species cultivation is its capability to accumulate cadmium (Cd) in the grains.
