Identification of nematode-responsive root-specific (NRRS) genes. The top level consists of A. thaliana root-specific probes identified through both meta-analysis and stand-alone analysis. However, M. incognita nematode-responsive probes were identified through meta-analysis alone. Below that are the genes that were the result of cross-comparison with nematode-responsive genes and root-specific genes sets. After identifying 51 NRRS genes, an LBI filter was imposed which reduced the number of genes to six with low basal expression under control conditions. Further screening, based on cis-elements, led to identification of three NRRS genes. The lowest level includes the final two LBI genes that have been identified based on the results of screening by experimentally validated cis-elements, identified in earlier studies.
