In excessive manner, mangan (Mn) as an essential nutrient can be toxic to the plant. This phenomenon often occurs in acid soil. Hence, it is needed gene resources to develop plant in acid soil. The soybean germplasm tolerance to Mn toxicity was tested in seed laboratory, using two factors experimental design. The first factor was Mn toxicity containing two treatments (1) 0 ppm Mn in pH 7 as control, and (2) solution concentration of 75 ppm Mn in pH 4. The second factor was 14 accessions of soybean germplasm. Results showed that generally root characters decreases while shoot characters increased in Mn toxicity condition. However, some genotypes showed different performance. There was one genotype having the highest root dry weight in Mn toxicity condition, i.e. MLGG 0091. The highest root dry weight in this genotype was also supported by the root length and number of roots. MLGG 0091 was also capable to increase the length epicotyle that contribute to the increase in seedling dry weight. Therefore MLGG 0091 can be used as a gene source for tolerance to Mn toxicity.

“…Therefore, the hipocotyle length increased in those four genotypes, with the highest increasing was achieved by MLGG 0984 as 17.17% (Tabel 2). In shortening of shoot, the high Mn concentration was also involved (Abou et al, 2002).…”

“…The response of antioxidative enzymes (superoxide dismutase, ascorbate peroxidase and glutathione reductase) was also examined in plants of the genus Alyssum under Ni 2+ and Cd 2+ stress (Schickler and Caspi, 1999). Recently the response of a new DNase in relation to nickel and manganese accumulation in Alyssum murale has been reported (Abou Auda et al, 2002). Furthermore, Ingle et al (2005) have suggested that ATP-phosphoribosyltransferase [ATP-PRT, the first enzyme involved in histidine (His) biosynthesis] expression is very important in regulating the pool of free His and that it contributes to the exceptional Ni tolerance of hyperaccumulator Alyssum species.…”

IntroductionAlthough heavy metals are toxic at high concentrations because of the damage they cause to plant metabolism, some metal-tolerant plants accumulate heavy metals within their aboveground tissues at high concentrations without any symptoms (Psaras et al., 2000;Pilon-Smits, 2005). Nickel hyperaccumulator plants are the largest group of metal hyperaccumulator plants with over 400 taxa, and the genus Alyssum L. (Brassicaceae) is the representative of this group with more than 50 nickelhyperaccumulating species (Broadhurst et al., 2009). The accumulated Ni concentration reaches nearly 3% of the leaf dry biomass in many Alyssum species (Krämer et al., 1996;Altınözlü et al., 2012).Serpentine soils are rich in heavy metals including nickel, cobalt, and chromium and are low in nutrients because they are derived from ultramafic rocks; therefore, a unique flora spreads out on such soil types (Prasad, 2005).Turkey is one of the major centers of hyperaccumulator plants as over half of the Alyssum species and over half of the hyperaccumulators are found in Turkey (Reeves and Adıgüzel, 2008). Alyssum murale Waldst. & Kit. and A. corsicum Duby are endemic to serpentine soils throughout Mediterranean Europe and are the species most often subjected to phytoremediation and phytomining studies because of their ability to grow in different types of soils (Brooks et al., 2000;Broadhurst et al., 2004). Plants hyperaccumulating heavy metals draw attention with the complex mechanisms they use to avoid the toxicity of heavy metals and where they accumulate such levels of heavy metals within the plant. Plants have a regulated system that consists of metal transport, chelation, transfer, and sequestration activities, all of which contribute to the uptake, distribution, and detoxification of metal ions (Clemens, 2001).
