Accumulation of caesium by arbuscular mycorrhizal symbioses on a cellular level
Journal Title: Екологічні науки - Year 2016, Vol 1, Issue
Abstract
The distribution of stable 133Cs isotope in structures of arbuscular mycorrhizal fungi Glomus intraradices and Glomus mosseae as well as in root tissues of Plantago lanceolata on the micro-scopic level is studied. The role of arbuscular mycorrhizal fungi in caesium accumulation in plant root system and impact of high caesium concentrations in soil on mycorhhizal colonization pa-rameters were considered. The comparative analysis of caesium and potassium uptake by mycor-rhizal and nonmycorrhizal P. lanceolata was conducted. It was found that arbuscular mycorrhizal fungi could participate in accumulation and transport of Cs to plants. The obtained results suggest that mycorrhiza limits caesium transfer and at the same time enhances potassium transport to aboveground part of plants.
