Physical, Chemical and Proteomic Evidence of Potato Suberin Degradation by the Plant Pathogenic Bacterium Streptomyces scabiei.

ABSTRACT: Potato peels consist of a tissue called phellem, which is formed by suberized cell layers. The degradation of suberin, a lipidic and recalcitrant polymer, is an ecological process attributed to soil fungal populations; however, previous studies have suggested that Streptomyces scabiei, the causal agent of potato common scab, possesses the ability to degrade suberin. In the present study, S. scabiei was grown in medium containing suberin-enriched potato phellem as the sole carbon source and its secretome was analyzed periodically (10- to 60-d-old cultures) with a special focus on proteins potentially involved in cell wall degradation. Although the amount and diversity of proteins linked to polysaccharide degradation remained high throughout the experiment, their abundance decreased over tim
