Improving soybean growth under arsenic stress by inoculation with native arsenic-resistant bacteria.

Certain metal (loid)-resistant bacteria that inhabit the rhizosphere have shown to improve plant growth and tolerance under toxic metal stress. In this study, we tested if six native, arsenic-resistant and plant growth promoting bacteria (PGPB) were able to enhance soybean (Glycine max L.) growth and modulate arsenic (As) uptake.
