Proteomic Analysis of Roots Response to Potassium Deficiency and the Effect of TaHAK1-4A on K⁺ Uptake in Wheat.

ABSTRACT: Potassium (K⁺) is essential for plant growth and stress responses. A deficiency in soil K⁺ contents can result in decreased wheat quality and productivity. Thus, clarifying the molecular mechanism underlying wheat responses to low-K⁺ (LK) stress is critical. In this study, a tandem mass tag (TMT)-based quantitative proteomic analysis was performed to investigate the differentially abundant proteins (DAPs) in roots of the LK-tolerant wheat cultivar "KN9204" at the seedling stage after exposure to LK stress. A total of 104 DAPs were identified in the LK-treated roots. The DAPs related to carbohydrate and energy metabolism, transport, stress responses and defense, and post-translational modifications under LK conditions were highlighted. We identified a high-a
