Exogenous auxin and cytokinin were expected to
generate marked changes in gene expression. Because
expression of key developmental regulators could be relatively small when ranked against this background, lenient
criteria were used for the initial selection of differentially
expressed genes (DEGs). Using MAS5 processed data,
each time point was compared pairwise with every other
time point, applying a fold-change threshold of 1.75, a
P-value cut-off of
