Flora of Turkey and the East Aegean Islands.

Heavy metal contamination of soil and water causing toxicity/stress has become one important constraint to crop productivity and quality. This situation has further worsened by the increasing population growth and inherent food demand. It have been reported in several studies that counterbalancing toxicity, due to heavy metal requires complex mechanisms at molecular, biochemical, physiological, cellular, tissue and whole plant level, which might manifest in terms of improved crop productivity. Recent advances in various disciplines of biological sciences such as metabolomics, transcriptomics, proteomics etc. have assisted in the characterization of metabolites, transcription factors, stress-inducible proteins involved in heavy metal tolerance, which in turn can be utilized for generating heavy metal tolerant crops. This review summarizes various tolerance strategies of plants under heavy metal toxicity, covering the role of metabolites (metabolomics), trace elements (ionomics), transcription factors (transcriptomics), various stress-inducible proteins (proteomics) as well as the role of plant hormones. We also provide a glance at strategies adopted by metal accumulating plants also known as “metallophytes”.

Plants are the target of a wide range of pollutants that vary in concentration, speciation, and toxicity. Such pollutants mainly enter the plant system through the soil (Arshad et al. 2008) or via the atmosphere (Uzu et al. 2010). Among common pollutants that affect plants, lead is among the most toxic and frequently encountered (Cecchi et al. 2008; Grover et al. 2010; Shahid et al. 2011). Lead continues to be used widely in many industrial processes and occurs as a contaminant in all environmental compartments (soils, water, the atmosphere, and living organisms). The prominence of environmental lead contamination results both from its persistence (Islam et al. 2008; Andra et al. 2009; Punamiya et al. 2010) and from its present and past numerous sources. These sources have included smelting, combustion of leaded gasoline, or applications of lead-contaminated media (sewage sludge and fertilizers) to land (Piotrowska et al. 2009; Gupta et al. 2009; Sammut et al. 2010; Grover et al. 2010). In 2009, production of recoverable lead from mining operations was 1690, 516, and 400 thousand metric tons by China, Australia, and the USA, respectively (USGS 2009).

Lead Uptake, Toxicity, and Detoxification in Plants

One of the most important environmental pollutants is cement dust. In this study, RAPD technology was used to define the potential genotoxic impact of cement dust on plants. For this purpose, the DNA comparison of 12 plant species( Convolvulus sepium, Astragalus christianus, Taraxacum androssovii Medicago varia, Alyssum murale, Artemisia spisigera, Falcaria vulgaris, Anchusa strigose, Glaucium leiocarpum, Salvia syriaca, Cryciata taurica Tragopogon albinervis)collected from the areas of 10000 m (Control area) or 0-100 m away from Askale cement factory in Erzurum; was performed. 16 primers were used, and 390 bands were obtained. Important differences were observed in plant RAPD profiles collected from 0-100 m areas when compared to their respective controls (10000 m away from the factory). Some bands in control plants got lost, and new band formations were observed. The Genomic template stability (GTS) value decreased significantly in plants collected from 0-100 m area as compared to the controls (%56.20). Soil samples from 0100 m and control area were collected and examined for their heavy metal contents. According to the analysis results, Nickel, Cadmium, Zinc, Lead and Copper concentrations were found to be dramatically high in the soil collected from 0100 m as compared to the control area. These results indicate that the high heavy metal content in the soil causes the changes in RAPD profiles and GTS in plants. The data also indicated that RAPD and GTS assays are basic, effective and reproducible means of the genotoxicity control of environmental pollution.
