Figure two: Number of nuclei per spore

**Figure two: Number of nuclei per spore**. The spore diameter of juvenile and mature spores (y) plotted against the number of nuclei in spore (x). **A**, ^{2 }= 0.576); **B**, ^{2 }= 0.358); **C**, ^{2 }= 0.525); and **D**, ^{2 }= 0.352). All slopes were statistically significant at

We would like to correct equations of these linear regressions in the text in page 3 as follow:

We found a positive linear relation between the number of nuclei in a given spore and its diameter for all AMF taxa: ^{2 }= 0.576), ^{2 }= 0.358), ^{2 }= 0.525) and ^{2 }= 0.352). All slopes were statistically significant at

We apologise for any inconvenience that this inaccuracy in presentation of the data used in the article
