Abstract excerpt
Coordination between the activity of ion transport systems in the root and photosynthesis in the shoot is a main feature of the integration of ion uptake in the whole plant. However, the mechanisms that ensure this coordination are largely unknown at the molecular level. Here, we show that the expression of five genes that encode root NO(3)(-), NH(4)(+), and SO(4)(2-) transporters in Arabidopsis is regulated...
