Spectrum and frequency of mutations induced by gamma rays and EMS in okra [Abelmoschus esculentus (L.) Moench]

open access: yesElectronic Journal of Plant Breeding, 2017
The seeds of okra variety P-8 were treated with different concentrations of gamma rays (65kR, 75kR and 85kR), EMS (1.2%, 1.4% and 1.6%) and their combinations to obtain the phenotypic response during M2 generation.

The Role of Stromal Tumor Environment in Advancing Skin Cancer Diagnosis and Treatment

open access: yesInternational Journal of Dermatology, EarlyView.
ABSTRACT The stromal tumor environment (STE) plays a vital yet often underrecognized role in cancer progression, shaping tumor development. It influences complex interactions among stromal cells, immune cells, extracellular matrix (ECM) components, and signaling molecules.

Induced mutations in cowpea, Vigna unguiculata (Leguminosae)

open access: yesRevista de Biología Tropical, 1998
Two cowpea (Vigna unguiculata L. Walp) varieties, IT84E-124 and Vita 7 of the International Institute of Tropical Agriculture, Ibadan, were exposed to varying doses of chemical and physical mutagens.

Isolation and characterization of a spore development mutant in Pyropia yezoensis (Rhodophyta) induced via insertional mutagenesis

open access: yesJournal of Phycology, EarlyView.
Abstract Mechanistic elucidation of spore development is essential for understanding reproductive strategies and improving seaweed cultivation. In this study, we isolated a mutant with spore development defects in Pyropia yezoensis (Rhodophyta) from among genetic transformants generated via insertional mutagenesis. We characterized the mutant phenotype

Atmospheric chemistry of gas-phase polycyclic aromatic hydrocarbons: formation of atmospheric mutagens.

open access: yesEnvironmental Health Perspectives, 1994
The atmospheric chemistry of the 2- to 4-ring polycyclic aromatic hydrocarbons (PAH), which exist mainly in the gas phase in the atmosphere, is discussed. The dominant loss process for the gas-phase PAH is by reaction with the hydroxyl radical, resulting

Gamma rays and EMS induced Flower Color Mutation in Grasspea (Lathyrus sativus Linn.)

open access: yesJournal of Agricultural Sciences, 2017
To induce flower color mutants in Grasspea (Lathyrus sativus Linn.) variety “Pusa-24“, the fresh seeds were exposed to 4 different doses of gamma radiation as physical mutagens (100, 200, 300 and 400 Gy) and treated with 4 different concentration of ...

Characterizing the structural variations in the genome of the mandarin variety, IrM2, induced by gamma irradiation

open access: yesPlant Biotechnology Journal, EarlyView.
Summary Fruits with few or no seeds are favoured by consumers because they provide an improved eating experience alongside other important quality traits such as taste and shelf‐life. Gamma irradiation has been widely used to induce favourable trait changes in plants, including a reduction in seediness.

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 ...
