In the present study three cDNA fragments were cloned using degenerate primers for Mn-sod genes and PCR: two showed a high degree of identity with Mn-sods from plants and the third with Fe-sod. Arbuscular mycorrhizal (AM) symbiosis down-regulated their expression pattern under well-watered conditions. In contrast, AM symbiosis in combination with drought stress considerably increased the expression of the Mn-sod II gene and this correlated well with plant tolerance to drought. These results… Expand
