We report the protective effects of mycorrhization with the fungus Tuber borchii in seedlings treated with heavy metals.

Leaves’ chlorosis induced by heavy metals is remarkably reduced in mycorrhized seedlings compared with non mycorrhized seedlings.

In mycorrhized seedlings, treatment with heavy metals does not reduce expression of genes involved in chlorophyll biosynthesis.

DNA damage induced by HM stress is lower in mycorrhized than in non mycorrhized seedlings.
