Proteomics and interactomics in grapevine: the next level in the study

To understand the cellular biology and biochemistry of plant cell behavior, there is not only one approach for studying proteins which are directly responsible for cellular activity. However, despite the enormous quantity of information generated by transcriptome analysis, the picture is still incomplete. The proteomic and interactomic approaches present a new point of view that so far has been missing. Comparative proteomics provide a powerful means to study products of genes and their regulation. On the other side, interactomes of different species can provide information about the evolutionary mechanisms leading to organism diversity. Then, this analysis allows scientists to better understand how complex biological processes are regulated and evolved.
