Template corresponding to GCAGTTCTCTATGAATATA from exon 7 of the hth gene.
Embryos injected with both hthdsRNA.exon6 and hthdsRNA.exon7 show a transformation of segmental identities in the abdomen; A1 is partially transformed toward A2, and A2is transformed to A3, on both the ventral and dorsal surfaces. These embryos also have segmental fusions at a frequency of less than 40% and their Keilin's organs (KOs) are often abnormal.
dsRNA has been synthesised from the template and injected into embryos, along with hthdsRNA.exon6, to study the phenotypic consequences of dsRNA interference (RNAi) of the hth gene.
