Developmental expression and evolution of hexamerin and haemocyanin from Folsomia candida (Collembola).

ABSTRACT: Haemocyanins constitute a group of copper-containing respiratory proteins, and hexamerins were derived from hexapod haemocyanin but lost the ability to transport oxygen and serve as storage proteins. Although hexamerins have been reported in most insect species, none of them has been identified in Collembola, one of the most primitive hexapod lineages, thereby preventing us from exploring relevant evolutionary scenarios regarding the origin and evolution of hexamerins in hexapods. Here we report on collembolan hexamerins for the first time, and investigated the temporal expression profiles of hexamerin and haemocyanin in the collembolan Folsomia candida. Haemocyanin was expressed over the entire life cycle, with higher expression at the embryonic stage than at other stages, whereas hexamer
