Sense gene expression across the Ha Locus at 14 days post anthesis. Each bar represents the median relative intensity of hybridisation to a 30 mer oligo. Oligo names represent the position of the first base in the oligo within the Ha locus sequence [GenBank accession CR626934]. Hybridisations were performed with cDNA from 14 dpa endosperm and revealed the ability of the microarray approach to predict the genic regions as defined in GenBank accession CR626934. Thin black lines (under the graph) indicate the gene regions with the thick black lines highlighting the coding sequences. The array also highlights areas of transcription found in the inter-genic regions (indicated by an asterisk).
