Effect of induced mutagenesis in M1 and M2 generations of cumin (Cuminum cyminum L.)

Electronic Journal of Plant Breeding, 2023
Cumin is an important spice that has been used for centuries in various cuisines around the world. Two cumin varieties (GC 3 and GC 4) were subjected to mutation to understand macromutational modifications.

Lymphocyte Micronucleus Formation Is Driven by Inflammation‐Induced Oxidative DNA Damage in Oesophageal Cancer Development

International Journal of Cancer, EarlyView.
Chromosomal instability is a hallmark of cancer, but minimally invasive ways to detect systemic DNA damage and cancer risk remain limited. Here, using patient blood samples, the authors investigated lymphocyte micronuclei (MN) frequency as a potential marker of DNA damage across the progression from gastroesophageal reflux disease to Barrett's ...

Environmental Pesticide Exposure in the Etiology of Pediatric Brain Tumors and Leukemia: A Scoping Review of Epidemiological Studies

International Journal of Cancer, EarlyView.
ABSTRACT Pediatric cancer is a significant cause of morbidity and mortality in children. The etiologies of pediatric cancer are largely unknown, but environmental pesticide exposures are likely to contribute. Chronic low‐dose exposure to pesticide mixtures through drinking water is a growing concern in agricultural communities.

A comparison of transgenic rodent mutation and in vivo comet assay responses for 91 chemicals. [PDF]

, 2019
A database of 91 chemicals with published data from both transgenic rodent mutation (TGR) and rodent comet assays has been compiled. The objective was to compare the sensitivity of the two assays for detecting genotoxicity.

Analysis of induced genetic variability for morphological and floral characters with male sterility in sesame (Sesamum indicum L.)

Electronic Journal of Plant Breeding, 2018
Male sterility can be useful to obtain high yielding sesame hybrids with reduced cost and labour. It can be induced artificially into the released cultivars by using chemical mutagens.

EFFECT OF GAMMA IRRADIATION, ETHYLEMETHANE SULPHONATE AND THEIR COMBINATIONS ON PERFORMANCE OF PEA (Pisum sativum L.) [PDF]

Journal of Plant Production, 2004
Seeds of three cultivars of pea Pisum sativum L. were irradiated with different doses of gammar-rays (2.5, 5, 10, 15,20,25 and 30 KR). Other portions the some of seeds were treated with different levels of EMS (0.025, 0.05 and 0.1 %).

Miniaturized Droplet‐Based Adaptation of the Ames Test for High‐Throughput Mutagenicity Assessment

Journal of Applied Toxicology, EarlyView.
ABSTRACT This work presents the first demonstration of a tube‐based droplet microfluidic implementation of the Ames test, bridging single‐droplet resolution with regulatory genotoxicity testing. The Ames test is a cornerstone assay for detecting mutagenicity, but conventional plate‐ and well‐based formats suffer from high reagent consumption, low ...

Mussel eggs as indicators of mutagen exposure in coastal and estuarine environments [PDF]

, 1994
The aim of this study was to develop a short-term genotoxicity assay for monitoring the marine environment for mutagens. Based on the developing eggs and embryos of the marine mussel Mytilus edulis, an important pollution indicator species, the test ...

Biochemical mutagens affect the preservation of fungi and biodiversity estimations [PDF]

, 2013
Many fungi have significant industrial applications or biosafety concerns and maintaining the original characteristics is essential. The preserved fungi have to represent the situation in nature for posterity, biodiversity estimations, and taxonomic ...
