Table 1. Sequence homologies and expression profiles of differentially expressed clones.

^aResults from a search in the non-redundant protein database with the BLASTX algorithm, except for Srdd14 where BLASTN was used to search the non-redundant DNA sequence database. ‘-’, no significant homology was found (see ^c).

^bE score for the most homologous sequence as given by the BLASTX or BLASTN algorithm; 10^–3 was used as the significance limit.

^cRelative expression levels in uninfected root primordia (-) and primordia harvested at different timepoints (1, 2, 4, 8, 12 and 48 h) after inoculation with A.caulinodans indicated by signs (– to +++, reflecting undetectable to maximal expression) and shading (the darker the shading, the stronger the expression).

^dHomologies only obtained by performing BLAST searches with larger cDNA fragments, e.g. Srdd6b (accession no. AJ309066), Srlox1 (accession no. AJ309069) and SrCLB1 (accession no. 309072).
