Metalaxyl Effects on Antioxidant Defenses in Leaves and Roots of Solanum nigrum L.

Frontiers in Plant Science, 2017
Overuse of pesticides has resulted in environmental problems, threating public health through accumulation in food chains. Phytoremediation is a powerful technique to clean up contaminated environments.

KDM4A Erases the H3R17me2a Mark, Facilitating Chromosome Condensation

Advanced Science, EarlyView.
This study reveals a reversible histone modification switch governing chromosome condensation during mitosis. PKCα‐activated KDM4A removes H3R17me2a, permitting Suv39h1‐driven H3K9me3 deposition. This epigenetic transition recruits the chromosomal passenger complex and triggers Aurora B‐dependent H3S10 phosphorylation, coordinating chromatin remodeling

Abolishing activity against ascorbate in a cytosolic ascorbate peroxidase from switchgrass

Phytochemistry, 2013
Switchgrass (Panicum virgatum L.) is being developed as a bioenergy species. Recently an early version of its genome has been released permitting a route to the cloning and analysis of key proteins. Ascorbate peroxidases (APx) are an important part of the antioxidant defense system of plant cells and present a well studied model to understand structure-

The Regulatory Role of Iron Transporter SLC39A13 in Liver Fibrosis

Advanced Science, EarlyView.
SLC39A13/ZIP13, a newly discovered intracellular iron transporter, delivers iron to the ER/Golgi to catalyze procollagen hydroxylation during collagen maturation. Here, we systematically characterize the cell type‐specific functions of ZIP13 across distinct hepatic cell populations, and identify hepatic stellate cell‐specific ZIP13 as a promising and ...

Valsa mali Pathogenic Effector VmPxE1 Contributes to Full Virulence and Interacts With the Host Peroxidase MdAPX1 as a Potential Target

Frontiers in Microbiology, 2018
The Valsa canker, caused by Valsa mali (V. mali), is a destructive disease of apple in Eastern Asia. Effector proteins are important for fungal pathogenicity. We studied a candidate effector VmPxE1 isolated based on the genome information of V. mali.

Sirt3 Genetically Engineered Apoptotic Bodies Alleviate Skeletal Aging by Limiting Aggravated NLRP3 Inflammasome Activation of Senescent Macrophages

Advanced Science, EarlyView.
The senescence of macrophages leads to a decrease in the expression of Sirtuin3 (Sirt3), which in turn aggravates the NLRP3 inflammasome activation and IL‐1β secretion, thereby promoting the aging‐related osteoporosis. Sirt3‐enriched apoptotic bodies (ABs‐Sirt3) generated through genetic editing approaches can alleviate skeletal aging by targeting ...

Metarhizium anisopliae Mitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

Advanced Science, EarlyView.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...
