Genes selected for this survey.

aInferred evolutionary source of gene.bNumber of ESTs in a previous survey [10].cTandem repeat genes are repeats of the same gene in a series demonstrated with PCR and sequencing using outwardly directed primers.dPCR and sequencing with a general spliced leader primer and a gene specific reverse primer. If this PCR was unsuccessful, but was amplified from the same cDNA using gene specific primers then the entry is marked “present”.eIf genomic amplification using inwardly directed primers, followed by sequencing produced a genomic complement to the EST.fThe number of introns found by comparing the expressed and amplified portions of the genomic sequences.gThe intergenic amplicon was used as a proxy for a forward genomic amplicon, since the intergenic amplicon covered almost the entire coding region of these genes.
