Project description:Negatives effects induced by exposure to ultra-violet (UV) radiation are well known. Nevertheless the modes of action of UV radiation are not well understood, in particular in soil invertebrates. In the present work, the effects of two UV doses (mimicking worst case scenarios in earth crust) on gene expression profile of Enchytraeus crypticus (Enchytraeidae, Oligochaeta) were investigated using the high-throughput 4 x 44K microarray developed for the species.
Project description:Iron is the fourth most abundant element in the Earth’s crust. However, the poor solubility of iron due to oxidation of ferrous iron to the almost insoluble ferric iron under aerobic conditions constitutes a considerable challenge for living organisms to obtain sufficient amounts of the iron available. In the present study, we set out to characterize the global gene expression of C. glutamicum under iron limitation in comparison to iron-replete conditions.
