A Ca ²⁺ signaling pathway regulates a K ⁺ channel for low-K response in <i>Arabidopsis</i>

Nutrient sensing is critical for plant adaptation to the environment. Because of extensive farming and erosion, low content of mineral nutrients such as potassium (K + ) in soils becomes a limiting factor for plant growth. In response to low-K conditions, plants enhance their capability of K + uptak... View More
