 When genes are conserved between the available nematode species, comparative analysis can also be very informative.WormBase encourages researchers to inform them via the help-desk if they have evidence for an incorrect gene structure.Any cDNA or mRNA sequence evidence for the change should be submitted to EMBL/GenBank/DDBJ; this helps in the confirmation and evidence for the gene model as WormBase routinely retrieve sequence data from these public databases.
