Identification of Differentially Accumulated Proteins Involved in Regulating Lead Stress in Sorghum Seedling Roots

Roots are important organs in plants that uptake water and nutrients from soil, and perceive and transduce various soil signals to shoots, which induce a suite of physiological, morphological, and molecular responses in the whole plant. Lead (Pb) is one of the most hazardous pollutants of the environment that is an ecological concern due to its impact on human health and the environment. In the present investigation, a high throughput proteome technique was performed to explore the differentially expressed proteins that are potentially involved in different level of Pb stress. Our results from the proteome level provide new evidence for further understanding the molecular mechanisms of the plant abiotic stress response.
