Fold difference in normalized microarray probe signal intensity for Arabidopsis MLN and MMN over the average of seventeen individual reference tissues (described in [17]). All genes listed here displayed a minimum two-fold increase in mean probe set signal intensity in MLN and/or MMN over each individual reference tissue, along with t-test p-values and false discovery rate (FDR) q-values of <0.05. Full lists of genes meeting these cutoff criteria via Arabidopsis microarray, along with average probe intensities and p and q-values for individual nectary samples, and corresponding number of B. rapa EST hits, are available in Tables S10 (MLN) and S11 (MMN). A total of 207 putative B. rapa orthologs to Arabidopsis nectary-enriched genes (MLN and/or MMN) were identified through this analysis.
Number of B. rapa ESTs from Table S9 (ESTs from all libraries combined) generating hits against Arabidopsis locus.
Nectary-enriched expression of ortholog in B. rapa verified by RT PCR, results shown in Fig. 3.
Expression patterns also previously confirmed for orthologs to At2g36190 [16] and At1g77110 (Ruhlmann and Carter, in preparation).
