Abstract Ethyl methanesulfonate is a chemical mutagen, which is currently being used in plant breeding, to increase genetic variability in genes of agronomic interest, of species useful in agriculture. It primarily causes single base point mutations by inducing guanine alkylation, resulting in GC to AT transitions. Its effect is different between clones of a genotype and between genotypes of the same species. This review presents the results obtained in recent research, where its effect on plant tissues, callus, and cells in suspension has been evaluated. Changes in the phenotypic expression of somaclonal variants were reported, involving morphology, production of secondary metabolites,… More >

Abstract The tulip (Tulipa sp.) is an ornamental plant produced by bulbs. Wild tulips are native to several areas of Iran, especially the Alborz and Zagros mountains. Endemic Iranian tulips are the origin of some commercial cultivars of tulip, and mutagens are commonly used to produce new traits and varieties. In this trial, X-rays were applied at 60, 70 and 80 kV; sodium azide (SA) at doses of 0.01%, 0.02%, and 0.03%, and diethyl sulfate (DES) at doses of 0.1%, 0.2% and 0.4 on Kess Nelis and Jan Van Ness varieties of tulip. Morphophysiological traits of the treated plants were measured.… More >
