Large-scale Proteomics Combined with Transgenic Experiments Demonstrates An Important Role of Jasmonic Acid in Potassium Deficiency Response in Wheat and Rice.

ABSTRACT: Potassium (K⁺) is the most abundant inorganic cation in plants, and molecular dissection of K⁺ deficiency has received considerable interest in order to minimize K⁺ fertilizer input and develop high quality K⁺-efficient crops. However, the molecular mechanism of plant responses to K⁺ deficiency is still poorly understood. In this study, 2-week-old bread wheat seedlings grown hydroponically in Hoagland solution were transferred to K⁺-free conditions for 8 d, and their root and leaf proteome profiles were assessed using the iTRAQ proteome method. Over 4000 unique proteins were identified, and 818 K⁺-responsive protein species showed significant differences in abundance. The differentially expressed protein species w
