Changes in sulphate uptake and accumulation along the primary root during tissue differentiation

  • Published:
Biologia Plantarum

Abstract

Experiments were made with the uptake of 35-S sulphate along the axis of the intact seminal root of maize seedlings.

Using short exposures the most intensive sulphur uptake was found in the apical 10 mm long region of the root. In the differentiating cells the maximum of sulphur uptake was in the first two 1-mm segments of the elongation zone immediately behind the meristem and then in the zone of the root hairs. Apart from the high activity in the area of the root hairs, two and three peaks, respectively, of increased sulphur accumulation were found in the area of the formation of laterals in case of longer exposure.
