A Comparative Analysis of Drought Tolerance Mechanisms in Triticum araraticum Jakubz. and Modern Bread Wheat (Triticum aestivum L.) Cultivars

Journal of Agronomy and Crop Science, Volume 211, Issue 4, July 2025.
ABSTRACT Wild wheat relatives are promising sources of drought tolerance that demonstrate adaptive mechanisms not found in modern wheat cultivars. This study investigated and compared the drought tolerance mechanisms in Triticum araraticum genotypes, a relatively unexplored species, with those of modern Triticum aestivum cultivars.

Ascorbate-glutathione cycle in wheat and rice seedlings under anoxia and subsequent reaeration

Вавиловский журнал генетики и селекции
The most important part of the plant antioxidant system is the ascorbate-glutathione cycle (AGC), the activity of which is observed upon exposure to a range of stressors, including lack of O2, and oxidative stress occurring immediately after the ...

The Mutualistic Fungus Piriformospora indica Protects Barley Roots from a Loss of Antioxidant Capacity Caused by the Necrotrophic Pathogen Fusarium culmorum

Molecular Plant-Microbe Interactions, 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 (subdivision ...

Dehydroascorbate and dehydroascorbate reductase are phantom indicators of oxidative stress in plants

, 1997
In many physiological studies dehydroascorbate (DHA) reductase is regarded as one of the chloroplast enzymes involved in the protection against oxidative stress. Here, evidence is presented that plant cells do not possess a specific DHA reductase.

Upregulation of Chloroplast Antioxidant System to Alleviate Salt Dependent Oxidative System in Rice Varieties [PDF]

Journal of Stress Physiology & Biochemistry, 2020
The chloroplast antioxidant system in pokkali (vytilla-2), kaipad (ezhome-1) and upland (koduvelliyan) rice varieties showed upregulation of enzymatic and non- enzymatic antioxidants under salt stress.

Advancements in Water‐Saving Strategies and Crop Adaptation to Drought: A Comprehensive Review

Physiologia Plantarum, Volume 177, Issue 4, July/August 2025.
ABSTRACT Drought stress, which is one of the most critical environmental constraints affecting global crop productivity, is exacerbated by climate change and increased atmospheric water demand. This review comprehensively examines plant responses to drought, integrating physiological, morphological, biochemical, and genetic adaptations that contribute ...

The Vacuolar Inositol Transporter BvINT1;1 Contributes to Raffinose Biosynthesis and Reactive Oxygen Species Scavenging During Cold Stress in Sugar Beet

Plant, Cell &Environment, Volume 48, Issue 5, Page 3471-3486, May 2025.
ABSTRACT Despite a high sucrose accumulation in its taproot vacuoles, sugar beet (Beta vulgaris subsp. vulgaris) is sensitive to freezing. Earlier, a taproot‐specific accumulation of raffinose was shown to have beneficial effects on the freezing tolerance of the plant.

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.
