  1. a Number of 'present' genes displaying a 3-fold or greater difference in probe signal intensity in ILN, MLN, & MMN over each individual non-nectary reference tissue; a t-test p value cutoff of 0.05, and false discovery rate (FDR) q value cutoff of 0.1 were initially applied to identify genes with significant differences in expression. The highest q value observed for any individual gene after applying the 3-fold cutoff was 0.081.
  2. b The overlapped common gene number represents those genes displaying significant changes that were expressed 3-fold or higher in a given nectary type over all individual reference tissues. The genes identified from this analysis were used to generate Additional file 7; a total of 270 unique genes were found to be upregulated in one or more nectary types over all individual reference tissues.
