Control of flavor development in wine during and after malolactic fermentation by Oenococcus oeni.

abstract：UNLABELLED:Mechanistic studies of many processes in Agrobacterium tumefaciens have been hampered by a lack of genetic tools for characterization of essential genes. In this study, we used a Tn7-based method for inducible control of transcription from an engineered site on the chromosome. We demonstrate that this method...
