Table I.
Microarray-based results of differentially expressed auxin-related genes in poplar roots after 3 DOII with the ectomycorrhizal fungus L. bicolor
Genes are listed by gene family and, within the gene family, by increasing transcript accumulation. From top to bottom: auxin-responsive transcription factors (PtaIAA), IAA-amido-synthetases (PtaGH3), auxin influx carriers (PtaAUX), and auxin efflux carriers (PtaPIN).
