ROS, Calcium, and Electric Signals: Key Mediators of Rapid Systemic Signaling in Plants |
Plant Physiology | Oxford Academic Skip to Main Content Advertisement Oxford Academic …

Potassium, mostly as a cation (K+), together with calcium (Ca2+) are the most abundant
inorganic chemicals in plant cellular media, but they are rarely discussed. K+ is not a …

Multiple cyclic nucleotide-gated channels (CNGCs) are abscisic acid (ABA)-activated Ca2+
channels in Arabidopsis (Arabidopsis thaliana) guard cells. In particular, CNGC5, CNGC6 …

Intracellular potassium homeostasis is a prerequisite for the optimal operation of plant
metabolic machinery and plant's overall performance. It is controlled by K+ uptake, efflux …

Their sessile lifestyle means that plants have to be exquisitely sensitive to their environment,
integrating many signals to appropriate developmental and physiological responses. Stimuli …

Systemic signaling pathways enable multicellular organisms to prepare all of their tissues
and cells to an upcoming challenge that may initially only be sensed by a few local cells …

Two highly specialized cells, the guard cells that surround the stomatal pore, are able to
integrate environmental and endogenous signals in order to control the stomatal aperture …

Stomatal guard cells are widely recognized as the premier plant cell model for membrane
transport, signaling, and homeostasis. This recognition is rooted in half a century of research …

As one of the most important mineral nutrient elements, potassium (K+) participates in many
plant physiological processes and determines the yield and quality of crop production. In this …
