“…The mutation results in the expression of the recessive allele, which implies in the phenotype of pink colouration. The high rate of pink cells, as well as the loss of reproductive capacity are indicative of mutagenicity (Ma et al, 1996). …”

“…Also using Tradescantia assays (stamen-hair mutation and micronucleus), Ma et al 2 found a positive association between mutagenesis and the distance from an incinerator in the United States. Similar findings (using the Tradescantia micronucleus test on emissions of municipal incinerators) were reported by Fomin and Hafner 3 in Germany.…”

The present work was designed to determine the potential genotoxicity at the vicinity of a solid waste incinerator in the metropolitan area of São Paulo, using the Tradescantia stamen-hair bioassay. Experiments were carried out between December 1998 and April 1999 in four regions (40 pots of plants per site) selected on the basis of their pollution levels predicted by theoretical modeling of the dispersion of the incinerator's plume. The exposure sites were defined as follows: highest level (incinerator); a high level (museum) located 1.5 km from the emission point; a moderate level (school, at a distance of 3.5 km from the incinerator); and a control (at Jaguariúna countryside). The difference in genotoxicity among the groups was statistically significant (p < 0.001). The frequency of mutations observed in the countryside was significantly lower [2.25 ± 1.55, mean ± SD (standard deviation)] than that of the sites close to the incinerator. The frequency of mutations measured at the school (3.70 ± 1.36) was significantly lower than that measured at both the museum (4.89 ± 1.12) and the incinerator (5.69 ± 1.34). In conclusion, we found a positive correlation between the spatial distribution of the emissions of the incinerator located in an urban area and the mutagenic events measured by the Tradescantia stamenhair assay. The in situ approach employed in this study was simple, efficient, and of low cost. No air or chemical extraction of pollutants was necessary for genotoxicity testing as required by other assays.

“…Tradescantia ve Vicia gibi bitkiler mikronükleus testinde sıklıkla kullanılırken, diğer bitkilerde de çalışmalar yapılmaktadır. Tradescantia bitkisinde "stamen hair mutasyonu" ve "mikronükleus test" olmak üzere iki ana test uygulanmakta olup, bu bitki üzerinde mikronükleus testi 1978'den bu yana kullanılmaktadır (Ma et al, 1994;Ma et al, 1994b;Ma et al, 1996). Elezaj et al (2011) termo elektrik santrallerinin etkilediği suların genotoksisitesini Tradescantia pallida'da mikronükleus testi ile araştırmış ve bu suların genotoksik etkisinin olduğunu göstermiştir.…”

ÖZETAraştırmacılar son yıllarda hem insanlar tarafından hem de doğal olarak meydana gelmiş birçok mutajenin varlığını açık bir şekilde göstermişlerdir. Bu mutajenler hava ve su kirleticilerinin yanı sıra gıdalar, ilaçlar, kozmetik ürünleri, pestisitler, ev yapımı ve endüstriyel kimyasallar gibi birçok kimyasal sınıfından meydana gelmektedir. Genotoksik kimyasalların artması ve radyasyon seviyesinin yükselmesi ile meydana gelen bu kirlilik artışı ekosistemi ve insanların da içinde bulunduğu tüm organizmaları olumsuz yönde etkilemektedir. Kontaminantların organizmalar üzerine etkisini belirlemek amacıyla hızlı ve kesin metotlara ihtiyaç vardır. Genotoksik maddelerin etkilerini tanımlayabilmek için birçok genotoksisite test sistemi geliştirilmiştir. Var olan birçok araştırma göstermiştir ki bitki biyotestleri çevredeki genotoksik kontaminasyonun değerlendirilmesi ve çevre kontrol sistemlerinde oldukça önemli metotlardır. Bitki testleri gen mutasyonları ve kromozom aberasyonları gibi geniş bir alanı kapsayan genetik hasarların belirlenmesini sağlamaktadır. Ayrıca diğer testlere göre oldukça hassas ve kolay uygulanabilen ve uluslararası geçerliliği olan bitki biyotestleri çevresel kirleticilerin genotoksik etkisinin belirlenmesinde sıklıkla kullanılmaktadır. Bu derleme ile bitkilerde yaygın olarak kullanılan genotoksisite ölçütü parametreler ve bu parametreleri içeren bazı çalışmaların değerlendirilmeye alınması amaçlanmıştır.Anahtar Kelimeler: Genotoksisite, mitotik indeks, mikronükleus, kromozom aberasyonu ABSTRACTResearcher over the last years has clearly demonstrated the presence of mutagens among the numerous man-made and naturally occurring chemicals in our environment.
