Procedures for the Study of Botrytis cinerea Proteome.

Proteomics has been revealed as a key set of technologies that provide a detailed description of the molecular processes involved in the development of a specific phenotype. "Omics" technologies can collect an incredible amount of information. Among them, proteomics is an invaluable tool for defining specific biological information by studying the complete set of proteins under specific conditions, the proteome; or specific subsets of proteins, the subproteome. It is a crucial instrument for describing protein post-translational modifications, the functional annotation of the genome, and the detection of orphan genes. Protein extraction procedures are necessary to obtain B. cinerea protein extracts of sufficient quality to be analyzed by LC-MS/MS, avoiding contaminants that interfere with the identification process. After experimental design, collect the samples and replicates as defined in each experimental approach; we will describe protocols and procedures for the next steps of proteome and subproteome extraction and LC-MS analysis.
