The role of Ala134 in controlling substrate binding and reactivity in ascorbate peroxidase [PDF]

, 2018
Ascorbate peroxidase (APX) is a class I heme peroxidase. It has two sites for binding of substrates. One is close to the γ-heme edge and is used for oxidation of ascorbate; the other is at the δ-heme edge and is used for binding of aromatic substrates ...

A comparative analysis of cell death signalling in RNA and DNA virus infections and potential inhibitory strategies

The FEBS Journal, EarlyView.
RNA and DNA viruses can manipulate host cell death through various mechanisms. RNA viruses (H1N1, SARS‐CoV‐2) induce acute apoptosis, necroptosis, and pyroptosis to promote rapid viral transmission and epithelial barrier damage. In contrast, DNA viruses (HSV‐1, EBV) regulate these mechanisms to sustain a lytic‐latency cycle, evade immune response and ...

Linoleic Acid Enhances Murine Natural Killer Cell Function In Vitro but Compromises Mitochondrial Bioenergetic Function During Retroviral Infection

Immunology, EarlyView.
Natural Killer (NK) cells are potent effectors against virus‐infected and tumour cells. During Friend Virus (FV) infection, fatty acid metabolism supports NK‐cell effector functions. Here, we found that NK cells from FV‐infected mice preferentially take up linoleic acid (LA), which reduced proliferation, mitochondrial function, and increased reactive ...

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

Abiotic Stress Tolerance in Plants: Myriad Roles of Ascorbate Peroxidase

Frontiers in Plant Science, 2017
One of the most significant manifestations of environmental stress in plants is the increased production of Reactive Oxygen Species (ROS). These ROS, if allowed to accumulate unchecked, can lead to cellular toxicity. A battery of antioxidant molecules is

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 ...

Physiological and molecular mechanisms of exogenous salicylic acid in enhancing salt tolerance in tobacco seedlings by regulating antioxidant defence system and gene expression

Frontiers in Plant Science
IntroductionSalt stress has emerged as a predominant abiotic factor that jeopardizes global crop growth and yield. The plant hormone salicylic acid (SA) has notable potential in mitigating salt toxicity, yet its mechanism in enhancing the salinity ...
