Random sequencing of cDNA clones from Eucalyptus globulus–Pisolithus tinctorius ectomycorrhizal tissues was carried out to generate expressed sequence tags (ESTs).  Database comparisons revealed that 42% of the cDNAs corresponded to previously sequenced genes.  These ESTs represent efficient molecular markers to analyze changes in gene expression during the formation of the ectomycorrhizal symbiosis.
