  1. aFold-change values were obtained from quantitative reverse-transcriptase polymerase chain reaction expression data (crossing threshold values) analyzed by SAS PROC GLM repeated measures analysis of variance. P values obtained from differences between control mycelia and P. sulphurascens-infected DF.
  2. bn/a = Not applicable; qRT-PCR amplification not reliable because fungal transcript levels were too low at some of the earlier points in the infection time course.
