![]() The migratory locust ( Locusta migratoria) is an important pest insect in Asia. ![]() To our knowledge, it’s the first time to report the role of CSN in behavior plasticity of animals. It suggests that CSN7A plays an essential role in the transition of gregaria towards solitaria in the migratory locust. Finally and importantly, RNA interference of CSN7A in gregaria resulted in obvious phase transition towards solitaria within 24 h. However, the mRNA level in the solitaria kept constant during the crowding rearing. The CSN7A had higher mRNA level in the gregaria as compared with the solitaria and the mRNA amount in the gregaria decreased remarkably during the 32 h-isolation. Subsequently, ten proteins including CSN7A were found to reveal differential mRNA expression profiles between the two phases. Gregaria revealed higher levels in proteins related to structure formation, melanism and energy metabolism, whereas solitaria had more abundant proteins related to digestion, absorption and chemical sensing. Firstly, 90 proteins were identified to express differentially between the two phases by quantitative proteomic analysis. ![]() Here, we report that COP9 signalosome complex subunit 7A ( CSN7A) is involved in the regulation of locust phase transition. This phenomenon is a typical kind of behavior plasticity. The migratory locust displays a reversible, density-dependent transition between the two phases of gregaria and solitaria. ![]()
