Optimal doses and concentrations of mutagens for winter wheat breeding purposes. Part I. Grain productivity [PDF]
Journal of Central European Agriculture, 2018 Evaluation of winter wheat mutant families (2011 – 2012, second – third generations, exclude a little number of dominant mutations at first generation) and lines (2013 – 2016, forth and next generations) has been carried out.

Concentration of mutagens from urine by absorption with the nonpolar resin XAD-2: cigarette smokers have mutagenic urine. [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 1977 A method is described for concentrating mutagens/carcinogens from human urine about 200-fold for subsequent assay in the Salmonella/mammalian microsome mutagenicity test.

Unboxing the molecular modalities of mutagens in cancer
Environmental science and pollution research international, 2021 The etiology of the majority of human cancers is associated with a myriad of environmental causes, including physical, chemical, and biological factors. DNA damage induced by such mutagens is the initial step in the process of carcinogenesis resulting in

Scientific Reports, 2019 Polycyclic aromatic compounds (PACs) are known due to their mutagenic activity. Among them, 2-nitrobenzanthrone (2-NBA) and 3-nitrobenzanthrone (3-NBA) are considered as two of the most potent mutagens found in atmospheric particles. In the present study

Detection of carcinogens as mutagens in the Salmonella/microsome test: assay of 300 chemicals.
Proceedings of the National Academy of Sciences of the United States of America, 1975 About 300 carcinogens and non-carcinogens of a wide variety of chemical types have been tested for mutagenicity in the simple Salmonella/microsome test.

Proceedings of the National Academy of Sciences of the United States of America, 1973 18 Carcinogens, including aflatoxin B(1), benzo(a)pyrene, acetylaminofluorene, benzidine, and dimethylamino-trans-stilbene, are shown to be activated by liver homogenates to form potent frameshift mutagens.

Archives of Toxicology, 2019 It is difficult to identify mutagen-induced genome-wide somatic mutations using next generation sequencing; hence, mutagenic features of each mutagen and their roles in cancer development require further elucidation.

PLoS ONE, 2023 Replication errors influence mutations, and thus, lifetime cancer risk can be explained by the number of stem-cell divisions. Additionally, mutagens also affect cancer risk, for instance, high-dose radiation exposure increases lifetime cancer risk ...

Principle and application of plant mutagenesis in crop improvement: a review
Biotechnology & Biotechnological Equipment, 2016 The first step in plant breeding is to identify suitable genotypes containing the desired genes among existing varieties, or to create one if it is not found in nature.

Induced Mutations Unleash the Potentials of Plant Genetic Resources for Food and Agriculture
Agronomy, 2013 The options for increasing food production by at least 70% over the next four decades so as to keep pace with a rapidly increasing human population are bedeviled by erratic climatic conditions, depleted arable lands, dwindling water resources and by the ...
