Induced sulfur metabolism by sulfur dioxide maintains postharvest quality of ‘Thompson Seedless’ grape through increasing sulfite content

Abstract BACKGROUND The commercial preservation of table grapes largely depends on the application of sulfur dioxide (SO2). However, little is known about whether SO2 participates in sulfur metabolism to improve the postharvest quality of table grapes. In this study, the contents of sulfur‐containing compounds, activities of enzymes, and expression of genes involved in sulfur metabolism in table g…
