Use Of Proteomics Tools To Investigate Protein Expression In Azospirillum Brasilense, Gurusahai K. Khalsa-Moyers

Doctoral Dissertations

Mass spectrometry based proteomics has emerged as a powerful methodology for investigating protein expression. “Bottom up” techniques in which proteins are first digested, and resulting peptides separated via multi-dimensional chromatography then analyzed via mass spectrometry provide a wide depth of coverage of expressed proteomes. This technique has been successfully and extensively used to survey protein expression (expression proteomics) and also to investigate proteins and their associated interacting partners in order to ascertain function of unknown proteins (functional proteomics). Azospirillum brasilense is a free-living diazotrophic soil bacteria, with world-wide significance as a plant-growth promoting bacteria. Living within the rhizosphere of cereal …
