A comparison of the effects of physical and chemical mutagens in sesame (Sesamum indicum L.)

open access: yesGenetics and Molecular Biology, 2010
Three sesame genotypes (Rama, SI 1666 and IC 21706) were treated with physical (γ-rays: 200 Gy, 400 Gy or 600 Gy) or chemical (ethyl methane sulphonate, EMS: 0.5%, 1.0%, 1.5% or 2.0%) mutagens and their mutagenic effectiveness and efficiency were ...

The Use of the Ames Test as a Tool for Addressing Problem-Based Learning in the Microbiology Lab

open access: yesJournal of Microbiology & Biology Education, 2012
Our environment is full of potential carcinogens such as UV light, industrial pollutants, pesticides, and food additives, among others. It is estimated that 90% of all carcinogens are also mutagens.

Nanomedicine Approaches for Autophagy Modulation in Cancer Therapy

open access: yesSmall Science, Volume 5, Issue 6, June 2025.
Autophagy modulation holds promise for enhancing cancer treatment, yet clinical translation remains challenging. This review explores nanomedicine‐based strategies to improve autophagy‐targeting drugs, highlighting their synergy with chemotherapy, immunotherapy, phototherapy, and gene therapy. It also discusses nanoparticle design and clinical progress,

Exploring the multifaceted dynamics of flowering time regulation in field crops: Insight and intervention approaches

open access: yesThe Plant Genome, Volume 18, Issue 2, June 2025.
Abstract The flowering time (FTi) plays a critical role in the reproductive success and yield of various crop species by directly impacting both the quality and quantity of grain yield. Achieving optimal FTi is crucial for maximizing reproductive success and ensuring overall agricultural productivity.

Micronucleus induction by 915 MHz Radiofrequency Radiation in Vicia faba root tips [PDF]

open access: yesarXiv, 2014
The mutagenic effect of radiofrequency electromagnetic field (RF-EMF) is evaluated by the micronucleus (MN) test in secondary roots of Vicia faba seedlings. Root exposures were carried out with 915 MHz continuous wave (CW) radiation for 72h, at power densities of 25, 38, 50 W/m$^2$.

Phenotypic and transcriptomic analysis reveals key genes associated with plant height in rubber tree and functional characterization of the candidate gene HbFLA11

open access: yesThe Plant Genome, Volume 18, Issue 2, June 2025.
Abstract The rubber tree (Hevea brasiliensis) is an important species in global natural rubber production. However, the mechanisms regulating the height of rubber trees remain poorly understood. In previous work, the dwarf mutant MU73397 was obtained through ethyl methanesulfonate mutagenesis.
