Abstract Cadmium (Cd) has seriously affected the quality of traditional Chinese medicinal material Salvia miltiorrhiza in recent years, threatening human health. The physiological and metabolic profiles of S. miltiorrhiza in response to Cd stress have been revealed in previous studies. However, transcriptional and post-transcriptional regulation in response to different degrees of Cd (0, 25, 50, and 100 mg/kg) stress in S. miltiorrhiza remains unclear. Here, transcriptome atlas in S. miltiorrhiza under different degrees of Cd Stress was unveiled using RNA sequencing (RNA-seq). These results showed that the profiles of gene expression were different in the response to Cd treatment. Defense More >

Abstract Water, minerals, nutrients, etc., can be shared by physiological integration among inter-connected ramets of clonal plants. Nitrogen plays an important role in alleviating cadmium (Cd) stress for clonal plants. But how different forms of nitrogen affect growth performance of clonal plants subjected to heterogeneous Cd stress still remains poorly understood. A pot experiment was conducted to investigate the differential effects of ammonium and nitrate on growth performance of Glechoma longituba under heterogeneous Cd stress. In the experiment, parent ramets of Glechoma longituba clonal fragments were respectively supplied with modified Hoagland solution containing 7.5 mM ammonium, 7.5… More >
