Abstract excerpt
KEY MESSAGE: The tonoplast-localized transporter TaTPK1-5D, interacting with TaCIPK23-4D , enhances low K⁺ tolerance in wheat by promoting vacuolar K⁺ efflux, providing a key genetic target for improving K⁺-use efficiency in breeding. Bread wheat (Triticum aestivum L.) serves as a staple food for more than one-third of the global population, and potassium (K+) is critical for wheat yield and quality. However, the...
