Information - SSS6 From soil genome to soil proteomics (co-listed in BG)
Event Information
The aim of this session is to discuss what it is known about the presence of genes and their expresssion in soil and the potential manipulation of both composition and activity of the soil microflora. One presentation will address the contribution given by molecular analysis to characterise microbial communies in soil and critically dicuss its benefits and possible disadvantages. Molecular techniques have allowed to overcome the problem of detecting unculturable microorganisms in soil. However, it is still problematic to evaluate microbial diversity in soil. A presentation will discuss what it is known about gene transcription in soil by discussing mRNA extraction and characterization and the ecological meaning of this approach. It is well-established that the statement “one gene one protein” is not anymore valid because the mRNA molecules can undergo post-transcriptional control and thus different protein isoforms can be generated from a single gene. In addition, the formed proteins can be subjected to post-translational modifications. Therefore, two presentations will deal with soil proteomics, an approach essential to characterize gene expression in soil, and the origin of soil enzymes, respectively. Finally two presentations will be devoted to the manipulation of microbial functioning in soil either through the use of genetically manipulated organisms or by soil management. It is well established that manipulation of both composition and activity of soil microflora can be essential to bioremediate polluted soils, limit nutrient losses, increase nutrient uptake by crops, control soil pathogens and promote the activity of microorganisms beneficial to plants.
