Plant litter decomposition is one of the most important ecosystem processes influencing elemental biogeochemistry across terrestrial and aquatic environments. Calcium (Ca), magnesium (Mg), and manganese (Mn) are essential nutrients, which play a key role in plant energy metabolism, photosynthesis, and merane transport of plants, and the major source of these nutrients is litter …
Visible light–excitable Ca2+ indiors offer several advantages over UV light–excitable indiors Fluo-4 Fluo-4 (), an analog of fluo-3 with the two chlorine substituents replaced by fluorine atoms (Figure 19.3.1), exhibits a K d for Ca 2+ of 345 nM (measured at 22 C using our Calcium Calibration Buffer Kits); the temperature dependence of the K d for fluo-4 has been reported.
