Abstract: Cadmium is a non-essential heavy metal for plant growth. Cadmium stress causes cell metabolism disturbance or death in plant. Here, we performed transcriptome analysis of Physcomitrella patens during cadmium stress by RNA-Seq. We revealed a new transcriptional network of cadmium stress in plants. The functions of genes that were upregulated or downregulated under cadmium stress included microtubule-based movement, microtubule-based processing, cytoskeleton organization, DNA replication, DNA metabolic process, telomere maintenance and organization, sexual reproduction, urea metabolic process, and nitrogen cycle metabolic process. These proteins may play roles in P. patens under cadmium stress. Our study provides new information for the further research of the molecular mechanisms of plant adaptation to cadmium stress.
