Sample TextSample Text Transgenic Arabidopsis thaliana were developed to increase tolerance for and accumulation of heavy metals and metalloids by simultaneous overexpression of AsPCS1 and YCF1 (derived from garlic and baker’s yeast) based on the fact that chelation of metals and vacuolar compartmentalization are the main strategies for heavy metals/metalloids detoxification and tolerance in plants. Dual-gene transgenic lines had the longest roots and the highest accumulation of Cd and As than single-gene transgenic lines and wildtype. When grown on cadmium or arsenic(arsenite/arsenate), Dual-gene transgenic lines accumulated over 2–10 folds cadmium/arsenite and 2–3 folds arsenate than wild type or plants expressing AsPCS1 or YCF1 alone. Such stacking modified genes involved in chelation of toxic metals and vacuolar compartmentalization represents a highly promising new tool for use in phytoremediation efforts. 以在植物中金属螯合物和液泡分隔对于重金属/非金属脱毒和耐受性是主要策略为基础，通过AsPCS1和YCF1（来源于大蒜和面包酵母）同步表达来开发转基因拟南芥增加耐受性和对重金属及非金属的富集能力。双基因的转基因品系与单基因的转基因品系和野生型相比具有最长的根和对镉和砷有最高的富集量。当增加镉或砷（亚砷酸盐/砷酸盐）的含量，双基因转基因品系比野生型或只表达AsPCS1或YCF1的植株富集镉/亚砷酸盐超过2-10倍和砷酸盐超过2-3倍。这种包含有毒金属螯合物和液泡分隔叠加修改基因意味着一个供植物修复工作很有前景的新工具。 |
