Fig. 3: Pollen has a unique transcriptional profile compared to other tissues.

a Heatmap of all differentially expressed genes (DEGs) in each inbred and their expression level in each tissue (normalized z-score). b Gene ontology (GO) terms enriched in genes up-regulated in pollen versus all other tissues for each inbred. NC350 is missing DEGs involved in telomere maintenance. This difference is shared with endosperm (Supplementary Fig. 2) c Upset plot of transcription start sites (TSS) identified by RAMPAGE in B73. The total number of TSS in each tissue is shown on the histogram on the left-hand side. The number of shared TSS between the different tissues are shown above the intersection matrix, color coded by genomic feature (including transposable element families). d Upset plot of the sRNA clusters identified in shRNA-seq in B73. The total number of clusters in each tissue is shown on the histogram on the left-hand side. The number of shared sRNA clusters between the different tissues are shown above the intersection matrix, color coded by genomic feature (including transposable element families).
