Allium Cepa Root Chromosomal Aberration Assay: A Review
Journal Title: Indian Journal of Pharmaceutical and Biological Research - Year 2013, Vol 1, Issue 3
Abstract
Higher plants, an important material for genetic tests to monitor various pollutant present in the environment. Among the plant species, Alium cepa has been used to evaluate chromosome aberrations and disturbances in the mitotic cycle. Now days, it has been used to assess a great number of genotoxic/antigenotoxic agents, which contributes to its increasing application in environmental monitoring. The A. cepa is commonly used as a test organism because it is cheap, easily available and handled and has advantages over other short-term tests. Among the endpoints of A. cepa root chromosomal aberrations, detection of chromosomal aberration have been the most used one to detect genotoxicity/ antigenotoxicity along the years. The mitotic index and chromosomal abnormalities are used to evaluate genotoxicity and micronucleus analysis used to verify mutagenicity of different chemicals. The Allium cepa root chromosomal aberration assay is widely used to determine genotoxic and antigenotoxic effects of different plant extracts.
