Some factors influencing the uptake and distribution of selenite in the bean plant (Phaseolus vulgaris)

Abstract

Three hours after the absorption of selenite by the roots ofPhaseolus vulgaris a major part of the Se accumulates in the roots while the fraction conveyed towards the aerial organs is unevenly distributed. Uptake and distribution are enhanced when plants are kept in darkness or when the nutritive solution is supplied with glucose, suggesting an active transport of selenite. However, when roots are soaked in a low temperature solution or supplied with metabolic inhibitors, the level of Se decreased by about 35% in the roots and in the aerial organs. So, part of the selenite enters the roots by diffusion, while another part is metabolically linked. Sugar translocated from the leaves is implicated as a co-transport-substance for selenite. Antibiotics, such as gramicidin, synthetised by micro-organisms, can also increase the level of Se within the bean plant.
