Transcriptome Response to Cadmium Exposure in Barley ( L.).

Cadmium is an environmental pollutant with high toxicity that negatively affects plant growth and development. To understand the molecular mechanisms of plant response to cadmium stress, we have performed a genome-wide transcriptome analysis on barley plants treated with an increased concentration of cadmium. Differential gene expression analysis revealed 10,282 deregulated transcripts present in the roots and 7,104 in the shoots.

Transcriptome of barley under three different heavy metal stress reaction.

In the present study, we used Illumina sequencing technology (HiSeq 2000) to sequence the transcriptome of barley ( L., cv. Morex) under three different heavy metal stress conditions: copper, zinc and cadmium.
