“…Total dry matter yield reduction reached 80 % for M. caesalpiniaefolia and 90 % for A. mangium. This result could be due to impairment of some metabolic processes by arsenic, such as ATP and chlorophyll synthesis, photosynthesis, cell division, and induction of oxidative stress and water stress (Dho et al, 2010;Zhao et al, 2010;Czech et al, 2011;Garg & Singla, 2011;Nascimento et al, 2011). The disruption of these processes often has a cumulative effect, culminating in severe growth reduction.…”

SUMMARYAcacia mangium and Mimosa caesalpiniaefolia are fast-growing woody fabaceous species that might be suitable for phytoremediation of arsenic (As)-contaminated sites. To date, few studies on their tolerance to As toxicity have been published. Therefore, this study assessed As toxicity symptoms in A. mangium and M. caesalpiniaefolia seedlings under As stress in a greenhouse. Seedlings of Acacia mangium and M. caesalpiniaefolia were grown for 120 d in an Oxisol-sand mixture with 0, 50, 100, 200, and 400 mg kg -1 As, in four replications in four randomized blocks. The plants were assessed for visible toxicity symptoms, dry matter production, shoot/root ratio, root anatomy and As uptake. Analyses of variance and regression showed that the growth of A. mangium and M. caesalpiniaefolia was severely hindered by As, with a reduction in dry matter production of more than 80 % at the highest As rate. The root/shoot ratio increased with increasing As rates. At a rate of 400 mg kg -1 As, whitish chlorosis appeared on Mimosa caesalpiniaefolia seedlings. The root anatomy of both species was altered, resulting in cell collapse, death of root buds and accumulation of phenolic compounds. Arsenic concentration was several times greater in roots than in shoots, with more than 150 and 350 mg kg -1 in M. caesalpiniaefolia and A. mangium roots, respectively. These species could be suitable for phytostabilization of As-contaminated sites, but growth-stimulating measures should be used.Index terms: arsenate, heavy metals, phytoremediation, root anatomy, soil contamination.(

“…The reduction in growth may be due to negative effects of As on cell metabolism, such as energy being channeled into the production of stress-related substances like antioxidases [2,35] and phytochelatins [36,37].Growth inhibition at higher concentrations may be linked with lower mitotic activity in the root meristematic zone or the inhibition of cell enlargement in the elongation zone as a consequence of decreased cellular turgor [30,38]. Root lengthening is controlled by the cell division rate in the apical meristems and by expansion and elongation of the newly formed cells and is considered to be one of the most sensitive endpoints of plant toxicity, where a dose-dependent inhibition of root growth (and of the whole plant), following the administration of relatively high doses of As, has been reported for wheat [26], mung bean [39], Arabidopsis thaliana [40], broad bean [41], and rice [29,42].…”

Ten Indian mustard (Brassica juncea L.) genotypes were screened for their phytoremediation potential for arsenic (As) contaminated water under laboratory-controlled conditions. The genotypes were grown in a hydroponic chamber for 20 days in 250-mL beakers containing As-contaminated water. During plant development, changes in plant growth, biomass, and total As were evaluated. Of the 10 genotypes (Pusa Agrani, BTO, Pusa Kranti, Pusa Bahar, Pusa Bold, Pusa Basant, Pusa Jai Kisan, Arka Vardhan, Varuna, and Vaibhav) Pusa Jai Kisan was the most effective in phytoremediating Ascontaminated water under hydroponic conditions. This will provide new information for Indian mustard genotypes for phytoremediating As-contaminated soils.

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.
