Research Abstract

There are considerable variations in the mode of caudal development among arthropods. This work aimed to understand the evolutionary mechanisms underlying these developmental variations. To this end, we searched for genes involved in the development of the caudal lobe in the chelicerate arthropod Achaearanea tepidariorum using in situ hybridization and oligonucleotide microarrays. Combined with RNA interference-based functional screening, we identified genes involved in the formation of the spider caudal lobe and head.
