↵a Log₂ of the signal ratio for the three pair-wise tissue comparisons as described for Table I. Log₂ values representing pair-wise comparisons between significantly different signals are indicated by a single asterisk.
↵b NS, Not significantly tissue biased in any pair-wise comparison or tissue biased in only one pair-wise comparison. Other abbreviations introduced in text.
↵c Terms used to describe vascular tissue roles for characterized genes are from Ye (2002). ?, Genes identified for this report that may play roles in vascular tissue differentiation or function.
