Comparative proteomics analysis of whitetop (Lepidium draba L.) seedlings in response to exogenous glucose.

In this research, a comparative proteomics approach was conducted to understand the physiological processes behind the sulforaphane formation in whitetop seedlings in response to exogenous glucose. Initially, 5-day-old whitetop seedlings were elicited by different concentrations (0, 166, 250, 277, 360 mM) of glucose for 72 h. According to the results, sulforaphane formation was influenced in a dose-dependent manner by glucose, and was maximized with the concentrations of 166 and 250 mM.

Long-term exposure of rapeseed (Brassica napus L.) to ZnO nanoparticles: anatomical and ultrastructural responses.

Rapid development of nanotechnology in recent years has raised concerns about nanoparticle (NPs) release into the environment and its adverse effects on living organisms. The present study is the first comprehensive report on the anatomical and ultrastructural changes of a variety of cells after long-term exposure of plant to NPs or bulk material particles (BPs). Light and electron microscopy revealed some anatomical and ultrastructural modifications of the different types of cell in the root and leaf, induced by both types of treatment.
