Induced variability in quantitative characters of groundnut (Arachis hypogaea L.) [PDF]

Electronic Journal of Plant Breeding, 2010
Groundnut genotype AK-280 was treated with EMS 40 mM, 60 mM, gamma rays 30 kR, 40 kR, 50 kR and combination treatment of EMS 20mM + gamma rays 20 kR. The observations on various quantitative characters were recorded in M2 generation.

Comparison of radiosensitivity of two rice (Oryza sativa L.) varieties to gamma rays and electron beam in M1 generation

Electronic Journal of Plant Breeding, 2017
The present study was carried out to compare effect of gamma rays and electron beam on two rice varieties viz., ADT-37 and ADT(R) 45. Dried seeds of both the varieties were treated with gamma rays and electron beam with different doses viz., 100Gy, 200Gy,

Gamma radiation: A potential tool for abiotic stress mitigation and management of agroecosystem

Plant Stress, 2022
Context: Being sessile, it is impossible for the plants to evade from the unfavourable environmental conditions prevailing due to various abiotic stresses like heat, salinity, drought, flood, heavy metals, and high radiance amongst many others.

High-energy Electromagnetic, Neutrino, and Cosmic-Ray Emission by Stellar-mass Black Holes in Disks of Active Galactic Nuclei

The Astrophysical Journal, 2023
Some Seyfert galaxies are detected in high-energy gamma rays, but the mechanism and site of gamma-ray emission are unknown. Also, the origins of the cosmic high-energy neutrino and MeV gamma-ray backgrounds have been veiled in mystery since their ...

CONSTRAINTS ON COSMIC RAYS, MAGNETIC FIELDS, AND DARK MATTER FROM GAMMA-RAY OBSERVATIONS OF THE COMA CLUSTER OF GALAXIES WITH VERITAS AND FERMI [PDF]

, 2012
Observations of radio halos and relics in galaxy clusters indicate efficient electron acceleration. Protons should likewise be accelerated and, on account of weak energy losses, can accumulate, suggesting that clusters may also be sources of very high ...

Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

Molecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Supernova Remnants in Gamma Rays

Universe
In the 1960s, the remnants of supernova explosions (SNRs) were indicated as a possible source of galactic cosmic rays through the Diffusive Shock Acceleration (DSA) mechanism.
