, able to chelate multiple metal ions i.e. the metallothioneins (MTs). They are widely distributed among Eucaryota, however, they have also been found in some limited Procaryota, including cyanobacteria, pseudomonads and mycobacteria. These bacterial MTs differ in terms of primary structure, the number and type of metal ions they bind, as well as with regard to their physiological functions. The expression of bacterial MTs is regulated by metals via metalosensors. MTs from cyanobacteria seem to be

PCA of roots, stems, and leaves (n = 6). S represents stems, R represents root, and L represents leaf.
Relative microbial abundances. The dominant bacterial phyla detected in roots, stems, and leaves of P. polyphylla var. yunnanensis were Cyanobacteria, Proteobacteria, Bacteroidetes, Firmicutes, and Actinobacteria (Fig. 5). In the roots, the main phyla were Cyanobacteria (53.47% of all detected bacteria), Proteobacteria (30.89%), Bacteroidetes (6.54%), Firmicutes (3.88%), and

, Planctomycetes, Cyanobacteria, Thermotogae, Verrucomicrobia, Choroflexi and Euryarchaeota were predominant groups from halophyte whereas Actinobacteria, Proteobacteria, Firmicutes, Cyanobacteria, Acidobacteria, Bacteriodetes, Planctomycetes and Verrucomicrobia were predominant phyla of wheat samples. Diversity and differences of microbial flora of Salsola and wheat suggested that functional interactions between plants and microorganisms contribute to salt stress tolerance.
