  1. All 454 reads were mapped (BLAST-n, default parameters) to the genome. TAIR XML files were parsed to obtain exon structure and location within the genome. Percentages were calculated for each class of sequence type. The number of genes does not equal the summation of gene components because there are some genes that are hit by multiple reads in different sections of the gene. The percent for each gene component is the percent of total reads.
