Metagenomics reveals the effects of potassium fertilizer gradients on soil phosphorus-cycling microbial communities and functional genes, and their relationship with yield [PDF]

open access: yesFrontiers in Microbiology
The rational application of potassium (K) is essential for soil nutrient transformation in orchards. Microbial communities drive phosphorus (P) transformation and activation, yet their responses to potassium (K) gradients and the underlying regulation of

Mitochondrial K+ Transport: Modulation and Functional Consequences

open access: yesMolecules, 2021
The existence of a K+ cycle in mitochondria has been predicted since the development of the chemiosmotic theory and has been shown to be crucial for several cellular phenomena, including regulation of mitochondrial volume and redox state.
