Subject: flybase update Dear Michael, We now have good evidence that one of the Ubx target genes listed in flybase (lips) corresponds to the previously described zygotic lethal, canoe. The reasons are 1) we have sequenced a strong canoe allele and found a stop codon near the beginning of the lips ORF and 2) in the most recent issue of Genes and Development, a Japanese group claims to have sequenced canoe. Unfortunately they are probably right: their sequence is nearly identical to our lips sequence. However, if you read their paper, I think you'll agree that their evidence for saying this is canoe is not very compelling. In any case, I think it is appropriate that the flybase entry is updated so that there isn't any confusion. We will hopefully be submitting our version of the canoe molecular biology for publication soon. Best regards, Richard
