Fig. 7From: Functional analysis of sense organ specification in the Tribolium castaneum larva reveals divergent mechanisms in insectsEvolutionary model of sense organ diversification in arthropods. The different colours represent additional diversity of morphology and function achieved by changes in the temporal expression and regulation of sensory genes. The numbers refer to the subsequent processes of sense organ development. See text for details. APs, accessory cell precursors; NPs, neural precursorsBack to article page
