Transcrptome Analysis Reveals Cesium Interferes with ABA perception and Stimulates Expression of Thiamine Biosynthesis Genes

Cesium (Cs) is known to exert toxicity in plants by competition and interference with the transport of potassium (K). However, the precise mechanism of how Cs mediates its damaging effect is still unclear. To identify putative genes that are functionally involved in this response, RNA-seq was conducted on Arabidopsis roots grown in low K and Cs medium conditions. Comparison of both stress condition reveals Cs alters ABA signaling during seed germination and induced expression of thiamine biosnynthesis genes. Overall design: Comparative gene expression analysis of Arabidopis root exposed to two stress condition, low potassium and cesium treatment.
