Abstract Because symbionts are experiencing major morphological changes during ectomycorrhiza development, the expression of genes encoding cytoskeletal proteins is likely altered. To test this contention, we have cloned and characterized in a α-tubulin cDNA (EgTubA1) from Eucalyptus globulus. A poorly-aggressive isolate (No. 270) of the ectomycorrhizal basidiomycete Pisolithus tinctorius caused no changes in root transcript levels of EgTubA1, whereas a drastic up-regulation in its expression was observed between 3 to 4 days after contact with the aggressive isolate 441. This enhanced α-tubulin expression coincided with the increase lateral root formation induced by fungal colonisation. The changes in α-tubulin expression support a role for cytoskeleton components in ectomycorrhiza development.
