Real-time imaging of 35 S-sulfate uptake in a rape seed plant

Abstract

We present real-time images of 35 S-sulfate uptake in a rapeseed plant visualized by the system we developed. In the leaves of rapeseed plants, 35 S accumulated in higher amounts and more rapidly in the more developed leaves. This real-time imaging system can be used to visualize the movement of both 35 S and 32 P in the same plant. In the pods of rapeseed, images of 35 S show that 35 S accumulated mostly in the terminal parts; on the other hand 32 P, when applied as 32 P-phosphoric acid, accumulated in the middle part of the pods.
