Project description:The complete chloroplast genome of Sedum lineare Thunberg, a plant widely occurring in most southern provinces of China, is assembled and characterized using Illumina sequencing data in this study. The genome is 149,257 bp in length, containing a large single-copy (LSC) region of 80,963 bp, a short single-copy (SSC) region of 16,648 bp, and two inverted repeat (IR) regions of 25,823 bp. It contains 130 genes, with 85 protein-coding genes, 8 rRNA genes and 37 tRNA genes. Moreover, the phylogenetic tree shows that S. lineare is closely related to Sedum japonicum.
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.
