“…Evaluation of the Cs + /K + ratio in P. abies showed a lower acquisition of 134 Cs by plants inoculated with Hebeloma crustuliniforme due to its retention in the outer hyphae and to a better transfer of K + to the plant (Brunner et al, 1996). By contrast, P. pinaster mycorrhized by R. roseolus displayed more elevated concentrations in 134 Cs than non-mycorrhized plants, whereas the K + content remained stable (Ladeyn et al, 2008), highlighting the importance of the considered host-symbiont couple. The influence of K + on 134 Cs accumulation was also investigated in AM symbiosis, in Medicago truncatula colonized by R. irregularis .…”

Potassium (K+) is one of the most abundant elements of soil composition but it's very low availability limits plant growth and productivity of ecosystems. Because this cation participates in many biological processes, its constitutive uptake from soil solution is crucial for the plant cell machinery. Thus, the understanding of strategies responsible of K+ nutrition is a major issue in plant science. Mycorrhizal associations occurring between roots and hyphae of underground fungi improve hydro-mineral nutrition of the majority of terrestrial plants. The contribution of this mutualistic symbiosis to the enhancement of plant K+ nutrition is not well understood and poorly studied so far. This mini-review examines the current knowledge about the impact of both arbuscular mycorrhizal and ectomycorrhizal symbioses on the transfer of K+ from the soil to the plants. A model summarizing plant and fungal transport systems identified and hypothetically involved in K+ transport is proposed. In addition, some data related to benefits for plants provided by the improvement of K+ nutrition thanks to mycorrhizal symbioses are presented.

“…Mycorrhizal symbiosis does not modify 85 Sr accumulation and transfer to the host plants, decreases the transfer of 95m Tc to the shoots by increasing its immobilisation in roots, and increases the transfer of 137 Cs to the shoots, although this effect is fungal species-dependent (Ladeyn et al, 2008).…”

“…The ability of EM fungi to solubilize minerals fixed in soil particles and accumulate the minerals may be important for the bioaccumulation of Cs by plants. Rhizopogon roseolus , which is an EM fungus, can increase the uptake of radiocesium by P. pinaster [29]. In contrast, the colonization of Q. serrata seedlings by the EM fungus Cenococcum geophilum reportedly decreases radiocesium uptake [30].…”

Influence of Ectomycorrhizal Colonization on Cesium Uptake by Pinus densiflora Seedlings

Radionuclides were deposited at forest areas in eastern parts of Japan following the Fukushima Daiichi Nuclear Power Plant incident in March 2011. Ectomycorrhizal (EM) fungi have important effects on radiocaesium dynamics in forest ecosystems. We examined the effect of colonization by the EM fungus Astraeus hygrometricus on the uptake of cesium (Cs) and potassium (K) by Pinus densiflora seedlings. Pine seedlings exhibited enhanced growth after the EM formation due to the colonization by A. hygrometricus. Additionally, the shoot Cs concentration increased after the EM formation when Cs was not added to the medium. This suggests that A. hygrometricus might be able to solubilize Cs fixed to soil particles. Moreover, the shoot K concentration increased significantly after the EM formation when Cs was added. However, there were no significant differences in the root K concentration between EM and non-EM seedlings. These results suggest that different mechanisms control the transfer of Cs and K from the root to the shoot of pine seedlings.
