Sequence And Functional Analyses Of Salinity Tolerance Genes Isolated From The Mangrove Plant, Acanthus Ebracteatus (Sea Holly) [PDF]

open access: yes, 2005
Salinity is a major abiotic stress that greatly affects plant growth and crop production. Most trees and crop plants are sensitive to salty conditions. Sodium ions are toxic to plants because of their adverse effects on potassium nutrition, cytosolic ...

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

open access: yesPhysiologia 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 FAD-Enzyme Monodehydroascorbate Radical Reductase Mediates Photoproduction of Superoxide Radicals in Spinach Thylakoid Membranes [PDF]

open access: yesPlant and Cell Physiology, 1998
The photoreduction of dioxygen in spinach thylakoid membranes was enhanced about 10-fold by the FAD-enzyme monodehydroascorbate radical (MDA) reductase at 1 fM. The primary photoreduced product of dioxygen catalyzed by MDA reductase was the superoxide radical, as evidenced by the inhibition of photoreduction of Cytc by superoxide dismutase.

Stage specific upregulation of antioxidant defence system in leaves for regulating drought tolerance in chickpea [PDF]

open access: yes, 2014
Leaf is one of the early sensors for the drought stress and is important to study drought tolerance mechanism. Activities of antioxidative enzymes and status of malondialdehyde (MDA), hydrogen peroxide (H2O2), proline and total phenols were studied in ...

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

open access: yesPlant, 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.

Light‐dependent regulation of ascorbate in tomato by a monodehydroascorbate reductase localized in peroxisomes and the cytosol [PDF]

open access: yesPlant Biotechnology Journal, 2012
SummaryAscorbate is a powerful antioxidant in plants, and its levels are an important quality criteria in commercial species. Factors influencing these levels include environmental variations, particularly light, and the genetic control of its biosynthesis, recycling and degradation.

Salts and nutrients present in regenerated waters induce changes in water relations, antioxidative metabolism, ion accumulation and restricted ion uptake in Myrtus communis L. plants [PDF]

open access: yes, 2017
The use of reclaimed water (RW) constitutes a valuable strategy for the efficient management of water and nutrients in landscaping. However, RW may contain levels of toxic ions, affecting plant production or quality, a very important aspect for ...

Nucleobase‐ascorbate transporter OsNAT9 regulates seed vigor and drought tolerance by modulating ascorbic acid homeostasis in rice

open access: yesThe Plant Journal, Volume 122, Issue 3, May 2025.
SUMMARY Drought and seed aging severely impact crop yield and seed vigor, respectively. Here, we identified the rice protein OsNAT9, a nucleobase–ascorbate transporter, as being crucial for seed vigor and drought tolerance. Knockout of OsNAT9 resulted in a significant reduction in seed vigor; however, the application of exogenous ascorbic acid (AsA ...

Exogenous sucrose influences antioxidant enzyme activities and reduces lipid peroxidation in water-stressed cucumber leaves

open access: yesBiologia Plantarum, 2015
To investigate whether exogenous sucrose can protect cucumber from water stress, cucumber (Cucumis sativus L.) seedlings were pretreated with 90 mM sucrose or 90 mM mannitol for 1 d and then were dehydrated with 10 % (m/v) polyethylene glycol (PEG) 6000 ...
