Genes selected for verification of statistical analysis using RT-PCR
TIGR LeGI gene ID and annotations were downloaded from the LeGI Web site. (AI63743 is a singleton and therefore retains its GenBank accession number.) ▴ indicates up-regulation of expression, and ▾ indicates repression of gene expression when REL, roots infected with egg-laying nematodes, are compared to uninfected tissue; s12–s36, susceptible roots infected 36 hpi compared to 12 hpi; and Resist, resistant roots compared to uninfected root tissue. Gene Group identifies category of genes identified in Table I: U = gene with unknown function; P = gene related to pathogen response. GC No. corresponds to clone DB number in GC library (Wilson et al., 1994).
