Chromosomal aberrations induced by Glycidol in Allium cepa L root meristem cells
Glycidol is used as a stabilizer in the manufacture of vinyl polymers and natural oils and as an intermediate in the synthesis of glycerol, glycidyl ethers, and amines. It is also used as an alkylating agent, demulsifier, and dye-leveling agent and for sterilizing milk of magnesia. Glycidol is an alkylating agent which reacts readily with glutathione; it causes a decrease in glutathione content...
متن کاملGenotoxicity of Industrial Paint Effluent on the Root Meristem of Allium Cepa
The genotoxic effects of the industrial effluent from a paint (100%, 50%, 25%, 10%, 5%, 1%, 0.50% and 0.25%) manufacturing company in Ikotun, Lagos was evaluated using the root meristem cells of Allium cepa. chromosomal aberration assays were used to determine the mitotic index and chromosome aberration rate. There was a significant difference (p<0.05) in the average root length of Allium cepa ...
متن کاملThe effects of fungicide benomyl (benlate) on growth and mitosis in onion (Allium cepa L.) root apical meristem.
In this study, the effects of benomyl, a systemic fungicide were investigated in the mitotic cell division in onion (Allium cepa) root tip cells during germination. For this aim, different concentrations (1, 2, 5, 10 and 20 mM) of benomyl solutions were used. All the concentrations used caused several abnormalities in mitotic cell divisions and the mitotic frequency in the onion root tip cells ...
متن کاملAnalysis of Nickel Induced Genotoxicity in Root Meristem of Allium cepa
Published: 15, August, 2013; Vol. No. 4(2):19-22; www.gbtrp.com; All Right Reserved, ©Gayathri Teknological Publication, 2013. Abstract Nickel induced genotoxic effect on Allium cepa root meristem was evaluated after treating onion root tips with various concentrations of NiCl2 in different time intervals. Mitotic index was higher (9.87 ± 1.96) at initial concentration of 10μg/l in three time i...
متن کاملCytotoxic and genotoxic effects of Br-containing oxaphosphole on Allium cepa L. root tip cells and mouse bone marrow cells
The continuous production and release of chemicals into the environment has led to the need to assess their genotoxicity. Numerous organophosphorus compounds with different structures have been synthesized in recent years, and several oxaphosphole derivatives are known to possess biological activity. Such chemical compounds may influence proliferating cells and cause disturbances of the genetic...
