随着重金属镉(Cd)污染日趋严重,找寻高效土壤Cd污染治理方法刻不容缓.以具有植物恢复潜力的栾树(Koelreuteria paniculata)作为研究对象,通过转录组学RNA-Seq测序研究不同浓度Cd胁迫后栾树地上部与根部基因表达与代谢通路的变化.转录组测序结果表明,共获得了65171条Unigenes,根中差异表达的基因显著多于茎叶,且下调表达的基因多于上调表达基因.GO富集结果表明,在Cd胁迫下细胞内核糖核蛋白复合物(Intracellular ribonucleoprotein complex)、核糖核蛋白复合物(Ribonucleoprotein complex)和大分子复合物(Macromolecular complex)是栾树根部差异表达基因主要富集部分.在地上部中,差异表达基因主要...

With the pollution of heavy metal cadmium (Cd) becoming more and more serious, it is urgent to find effective treatment methods for soil Cd pollution. In this study, Koelreuteria Paniculata, a plant species with potential for Cd recovery, was studied by transcriptome analysis to investigate gene expression and metabolic pathways in shoots and roots of K. paniculata under different concentrations of Cd. Transcriptomic RNA-seq results showed that a total of 65171 Unigenes were obtained. The differentially expressed genes in roots were significant...
