  1. A summary of results from Northern blots, RT-PCR and published data. GEFs are indicated in the left column and hours of development in the top row. gefJ is encoded by two separate but near-identical genes which cannot be differentiated at this level. *Northern Blot; RT-PCR. +++, strong band; ++, clear band; +, weak band; +/-, hardly detectable; -, no expression detected; ND, not done.
