Design of the array experiments. Thirty-six independent biological samples (or pools of staged tissues from the same tassel in the case of the anthers and pollen) were used for eight comparisons. The same aliquot of the W23 sample was used to hybridize to ND101/W23 and A619. Fluorescent dye labeling of each sample is indicated with colors: red for Cy5 and green for Cy3.
