ZmMS1 coordinates ROS homeostasis, lipid allocation, and male fertility for maize breeding applications

Journal of Integrative Plant Biology, EarlyView.
The redox‐sensitive transcriptional repressor ZmMS1 coordinates reactive oxygen species homeostasis and lipid allocation for pollen exine and anther cuticle formation. Loss or precocious expression of ZmMS1 causes male sterility. Constitutive overexpression induces dwarfism and semi‐sterility. These findings enable flexible maize male‐sterility systems

A NAC–MYB–cysteine regulatory module enhances drought and salt tolerance in soybean

Journal of Integrative Plant Biology, EarlyView.
In the GmNAC3—GmMYB60—GmCYS20 module, GmNAC3 represses the transcription factor gene GmMYB60 and GmMYB60 suppresses the cysteine biosynthetic gene GmCYS20. GmCYS20‐mediated cysteine metabolism feeds back to limit GmMYB60 activity. This transcription—metabolism circuit enhances stress tolerance and offers breeding targets for resilient soybean ...

S‑glutathionylation of MaWRKY44 orchestrates a MaZFP139‐MaWRKY44‐MaGSTU07 cascade to enhance banana cold tolerance

Journal of Integrative Plant Biology, EarlyView.
In banana, at low temperatures (7°C), the transcription factor MaZFP139 activates MaWRKY44 expression. MaWRKY44 binds to the W‐box sites in the promoter of the glutathione S‐transferase gene MaGSTU07 to enhance reactive oxygen species scavenging. S‐glutathionylation protects MaWRKY44 from oxidation‐induced degradation, reinforcing antioxidant defenses ...

The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Ascorbic Acid and Ascorbic Acid Oxidase in Vegetables

Ascorbic Acid and Ascorbic Acid Oxidase in Vegetables
Ascorbic acid, dehydroascorbic acid and total ascorbic acid content in fruits and vegetables and the amounts of remaining after 24 hours were measured and compared by high-performance liquid chromatography. Activity of ascorbic acid oxidase was determined in nine kinds of vegetables.

Serum Folate Concentration Corresponding to the Red Blood Cell Folate Threshold for Increased Risk of Neural Tube Defects Among Ethiopian Women of Reproductive Age

Maternal &Child Nutrition, EarlyView.
ABSTRACT Neural tube defects (NTDs) are severe birth defects linked to insufficient maternal folate status during early pregnancy. Red blood cell (RBC) folate concentration is the recommended biomarker for predicting NTD risk, with a threshold of 748 nmol/L using the US Centers for Disease Control and Prevention (CDC) microbiological assay. However, in
