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 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 کاملChromosomal and Nuclear Alterations in Root Tip Cells of Allium Cepa L. Induced by Alprazolam
INTRODUCTION Alprazolam is a triazolobenzodiazepine used in panic disorders and other anxiety states. Target organ of Alprazolam is CNS, causing depression of respiration and consciousness. AIM This study aimed to estimate the genotoxic potential of Alprazolam using Allium cepa test. METHODS Allium cepa is one of the most suitable plants for detecting different types of xenobiotics. The tes...
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 کاملCytological Effects of Blitox on Root Mitosis of Allium cepa L
The genotoxic potential of blitox (fungicide) was investigated by using chromosome aberration in Allium cepa root tip cells. Allium cepa roots were treated with 2g/lt., 3g/lt. and 4g/lt. concentrations of blitox and distilled water as control at 4 hours, 8 hours and 12 hours duration. The results indicated that blitox significantly increased the genetical abnormalities at all concentrations and...
