Oxidative Stress and NO Signalling in the Root Apex as an Early Response to Changes in Gravity Conditions

Figure 4

Oxygen concentration in the solution measured at two different levels, close to (distance < 1 mm) the root apex and to the root mature zone during three different parabolas: one parabola at the beginning (a), one in the middle (b), and one at the end of the experiment (c). Control experiment with no roots inside the Eppendorf vial is shown in (d).
