Mutagens manufactured in fungal culture may affect DNA/RNA of producing fungi

open access: yesJournal of Applied Microbiology, 2009
Self‐produced mutagens in culture by fungi may affect DNA analysis of the same fungi. This has not been considered previously. Many fungi produce numerous mutagenic secondary metabolites (SM) in culture.

African Horned Melon (Cucumis metuliferus): Climate‐Resilient Crop and Gene Donor in the Breeding of Major Cucurbits

open access: yesPlant Breeding, Volume 144, Issue 2, Page 159-181, April 2025.
ABSTRACT African horned melon (Cucumis metuliferus E. Meyer ex Naudin, 2n = 2x = 24) is an under‐researched and under‐utilised cucurbit crop primarily grown for its nutritious fruit. In its centre of diversity, the crop is valued for its relatively high tolerance to insect pests, diseases, drought and heat stress. It is a potential opportunity crop and

Mutagenic activity of river water from a river near textile industrial complex in Korea [PDF]

open access: yes, 2018
The mutagenic activity of XAD-2 adsorbates and water extracts recovered from nine locations of the Kumho River was tested on S. typhimurium TA98 strain to identify the source of the mutagenicity.

Interpreting the dependence of mutation rates on age and time [PDF]

open access: yesarXiv, 2015
Mutations can arise from the chance misincorporation of nucleotides during DNA replication or from DNA lesions that are not repaired correctly. We introduce a model that relates the source of mutations to their accumulation with cell divisions, providing a framework for understanding how mutation rates depend on sex, age and absolute time. We show that

Mutation activity of Lonicera caerulea population in an active fault zone (the Altai Mountains) [PDF]

open access: yesarXiv, 2015
Geophysical and geochemical anomalies may have a mutagenic effect on plants growing in active fault zones being the factors of evolutionary transformation of plant populations. To test this assumption we evaluated the mutation activity of a Lonicera caerulea natural population in one of the active fault zones in the Altai Mountains.

GeoScatt-GNN: A Geometric Scattering Transform-Based Graph Neural Network Model for Ames Mutagenicity Prediction [PDF]

open access: yesarXiv
This paper tackles the pressing challenge of mutagenicity prediction by introducing three ground-breaking approaches. First, it showcases the superior performance of 2D scattering coefficients extracted from molecular images, compared to traditional molecular descriptors.

A Novel Graph-based Approach for Determining Molecular Similarity [PDF]

open access: yesarXiv, 2016
In this paper, we tackle the problem of measuring similarity among graphs that represent real objects with noisy data. To account for noise, we relax the definition of similarity using the maximum weighted co-$k$-plex relaxation method, which allows dissimilarities among graphs up to a predetermined level.
