Gene expression and role in cadmium tolerance of two PLAC8-containing proteins identified in the ericoid mycorrhizal fungus Oidiodendron maius

In this work, we analyzed gene expression of OmFCR1 and OmFCR2 in the fungus O. maius Zn when exposed to cadmium, the ability of OmFCR2 to confer cadmium tolerance when expressed in yeast, and the growth of OmFCR1-null mutants of O. maius Zn upon cadmium exposure. Although OmFCR2 was also able to confer some cadmium tolerance to yeast, the different expression pattern of these two genes would suggest different roles in O. maius Zn.
