TL;DR: Two new bacteria species belonging to the genus Burkholderia sensu lato were isolated from rhizospheric roots of pioneer plant growing in New Caledonian ultramafic soils and were able to tolerate high metal concentrations and alleviated metal contents in roots of Tetraria comosa, an endemic pioneer herbaceous species growing on Newcaledonia.

TL;DR: Ni biosorption and bioaccumulation showed that BE exhibited a lower Ni content explained by the ability of this strain to produce exopolysaccharides involved in Ni chelation, and it was suggested that ultramafic C. citreum strains are more adapted to this substrate than C.citreum DSM20528T and their features allow them to enhance plant metal tolerance.

TL;DR: Analysis of the effects of soil P fertilization on growth, mineral nutrition and potentially toxic metal absorption of plants inoculated or not with AMF native isolates found positive effects of mycorrhizal symbiosis, such as better mineral nutrition, particularly for potassium and calcium and a higher calcium/magnesium values.
