Propagation of Gamma-Ray Burst Relativistic Jets in Active Galactic Nucleus Disks and Its Implication for Gamma-Ray Burst Detection

The Astrophysical Journal
The accretion disks of supermassive black holes (SMBHs) harboring in active galactic nuclei (AGN) are considered to be an ideal site for producing different types of gamma-ray bursts (GRBs). The detectability of these GRB phenomena hidden in AGN disks is

Observation of contemporaneous optical radiation from a gamma-ray burst

, 1999
The origin of gamma-ray bursts (GRBs) has been enigmatic since their discovery. The situation improved dramatically in 1997, when the rapid availability of precise coordinates for the bursts allowed the detection of faint optical and radio afterglows ...

A GLUTAMATE CYSTEINE LIGASE Gene StGSH1 Regulated by StERF10 Enhanced Glutathione Accumulation and Adaptation to Low Phosphorus Stress in Potato

Advanced Science, EarlyView.
The StERF10‐StGSH1 module coordinates glutathione (GSH) biosynthesis under low‐phosphorus stress. The low‐phosphate‐induced AP2/ERF transcription factor StERF10 directly activates the transcription of StGSH1 and enhances GSH accumulation. Consequently, GSH scavenges reactive oxygen species and provides sulfur for sulfolipid synthesis, facilitating the ...
