Potassium is one of the three main mineral nutrients, and is vital for leaf growth and the quality of tobacco (Nicotiana tabacum) plants. In recent years, the isobaric tags for relative and absolute quantitation (iTRAQ) method has been one of the most popular techniques for quantitative proteomic analysis. In this study, we used iTRAQ to compare protein(More)
