Project description:Root transcriptomes were sequenced using SOLiD 4 chemistry. The three accessions LC, GA and MP differed significantly in the expression of genes that contribute to metal ion transport and detoxification, stress tolerance and secondary metabolite biosynthesis. These data provide comprehensive genome-wide view to the root processes in several N. caerulescens accessions and highlight differences that potentially facilitate adaptation to various metalliferous soils. Comparison of three N. caerulescens accessions with contrasting metal accumulation and tolerance traits
Project description:A common reference model was used to design the microarray experiment, in which cDNA from T. caerulescens roots exposed to 100 uM (sufficient) zinc was used as the common reference. Every slide was always hybridized with the common reference sample and with a sample from one of the treatments (Arabidopsis or T. caerulescens exposed to deficient, sufficient or excess zinc). The common reference was labeled with the fluorescent dye Cyanine 3 (Cy3) and the treatment samples were labeled with Cyanine 5 (Cy5). As a quality control step we performed a dye-swap hybridization for one sample (from T. caerulescens roots exposed to sufficient zinc).
