Fluorophore-cored dendrimers for patterns in metalloprotein sensing

, 2009
In fluorophore-cored dendrimers with peripheral binding functionalities, the effect of generation upon protein binding-induced fluorescence quenching can be unpredictable; this is because the increase in fluorophore-binding functionality distance with ...

The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...
