Gene expression profiling of the early cadmium response includes abiotic stress signaling pathway in rice

ABSTRACT: Plant growth is severely affected by toxic concentrations of the non-essential heavy metal cadmium (Cd). Comprehensive transcriptome analysis by RNA-Seq following cadmium exposure is required to further understand plant responses to Cd and facilitate future systems-based analyses of the underlying regulatory networks. In this study, rice plants were hydroponically treated with 50 µM Cd for 24 hours. In total, ~60,000 transcripts, including transcripts that could not be characterized by microarray-based approaches, were evaluated and ~36,000 transcripts were responsive to Cd exposure. Among multigenic families that may protect cells from generated ROS and reduce Cd toxicity, prominently upregulated antioxidant enzyme genes were identified. Furthermore, 168 different metal ion transporter g
