^a Analysis performed with Athena [76, 77]. All overlapping significant genes from Additional file 7 were analyzed [96 genes total displaying 3-fold or greater change in normalized probe signal intensity in two or more nectary types (MLN, MMN, ILN) over all individual reference tissues].
^b Where M = A/C and W = A/T
