MsWRKY49 Modulates Pollen Tube Elongation in Response to Boron Deficiency by Regulating Reactive Oxygen Species Homeostasis in Alfalfa

Plant Biotechnology Journal, EarlyView.
ABSTRACT Boron, an essential micronutrient, plays a crucial role in plant reproductive processes. Boron deficiency is widespread in many regions and significantly reduces alfalfa (Medicago sativa) seed yield, yet the molecular mechanisms underlying its impact on reproductive organ development remain elusive.

Nitric oxide participates in the regulation of ascorbate-glutathione cycle and water physiological characteristics of Arabidopsis thaliana by NaHS

Photosynthetica, 2020
We investigated the role of nitric oxide (NO) in the regulation of ascorbate-glutathione (AsA-GSH) cycle and water physiological characteristics of Arabidopsis thaliana by sodium hydrosulfide (NaHS).

Analysis of Antioxidant Enzyme Activity Involved in Ascorbate-glutathione Cycle in Green-flesh Kiwifruits

IOP Conference Series: Materials Science and Engineering, 2018
To compare the activities of enzymes related to ascorbate-glutathione cycle (AsA-GSH cycle) in different varieties, the fruits of five green-fleshed kiwifruit varieties were used as materials and activities of ascorbate peroxidase (APX), monodehydroascorbic acid (MDHA), dehydroascorbate reductase (DHAR) were measured by ultraviolet spectrophotometry ...

Calmodulin‐Like Protein MfCML50 Interacts With Carveol Dehydrogenase in Medicago falcata to Regulate Cold Tolerance Through Mediating ROS Homeostasis

Plant Biotechnology Journal, EarlyView.
ABSTRACT Low temperature triggers Ca2+ signalling and reprogramming of gene expression and metabolism in plants. However, how the Ca2+ signal is transduced to the downstream metabolic pathways remains unknown. The involvement of a cold‐induced calmodulin‐like protein, MfCML50, from Medicago falcata in regulation of cold tolerance was examined in the ...

Multigene families encode the major enzymes of antioxidant metabolism in Eucalyptus grandis L

Genetics and Molecular Biology, 2005
Antioxidant metabolism protects cells from oxidative damage caused by reactive oxygen species (ROS). In plants, several enzymes act jointly to maintain redox homeostasis.

The miR164b‐SiNAC015 Module Regulates Drought Tolerance by Scavenging Reactive Oxygen Species in Foxtail Millet

Plant Biotechnology Journal, EarlyView.
ABSTRACT Drought is the major abiotic stress threatening global crop yields, thus identifying potential candidates with promising breeding value has become a central goal of current breeding programmes. Here, we found that miR164b functions as a negative regulator in plant drought tolerance, whose expression is dramatically inhibited under drought ...

The Relationship between Leaf Rolling and Ascorbate-Glutathione Cycle Enzymes in Apoplastic and Symplastic Areas of Ctenanthe setosa Subjected to Drought Stress

Biological Research, 2009
The ascorbate-glutathione (ASC-GSH) cycle has an important role in defensive processes against oxidative damage generated by drought stress. In this study, the changes that take place in apoplastic and symplastic ASC-GSH cycle enzymes of the leaf and ...

Biochemical responses of Hyacinth bean (Lablab purpureus) to salinity stress [PDF]

, 2010
Effect of salinity on Hyacinth bean, Lablab purpureus (HA-​4 cultivar) was evaluated in 10-​day old seedlings with 100-​500 mM NaCl over 72 h of exposure. The stress reduced dry and fresh wt., leaf surface area, root and shoot length, total chlorophyll,

Effector‐Mediated Spatial Reprogramming of Glycolate Oxidase Subverts Peroxisomal and Membrane‐Associated ROS Defences

Plant Biotechnology Journal, EarlyView.
ABSTRACT Oomycete pathogens secrete hundreds of RXLR effectors into plant cells to modulate host immunity by targeting diverse plant proteins. Here, we report that the Peronophythora litchii RXLR effector PlAvh133 acts as a virulence factor and targets the litchi glycolate oxidase (GLO) LcGLO1, a key enzyme in photorespiration, thereby suppressing ...
