Project description:The aim of this study is to investigate whether the known mechanisms of hyperaccumulaion in Brassicaceae hyperaccumulators (Arabidopsis halleri and Noccaea caerulescens) are conserved among different hyperaccumulating species or if there exist unknown mechanismsin other metal hyperaccumulating species.The comparison of transcriptomes between hyperaccumulator Sedum plumbizincicola and non-hyperaccumulator S. alfredii (NHE) was performed by taking advantage of next-generation sequencing.The data suggested that increased active uptake, long-distance transport and efficient chelation of heavy metals might represent common mechanisms occurred in various hyperaccumulators. Moreover, we found that those genes showing constitutively higher expression in S. plumbizincicola shoots are significantly enriched in processes related to cell wall metabolism, including biosynthesis/modification of cellulose, lignin, pectin, glucan, and other cell wall related components.

Transcription profiling by high throughput sequencing of heavy metal hyperaccumulator Sedum alfredii Hance (Crassulaceae).

Project description:RNA-seq was used to unveil the molecular mechanisms of Cd tolereance in Sedum alfredii Hance shoots Here we are submitting the expression abundance of each contig in two treatments (CK vs Cd) with three biological replicates. Sequences for the contigs were submitted to EMBL-Bank.
