摘要： Trehalose metabolism is critical for production of ATP, provision of carbon source, and facilitation of carbohydrate absorption. Trehalose-6-phosphate synthase (TPS) is a rate-limiting enzyme in trehalose biosynthesis. In the present paper, a TPS gene (LdTPS) was cloned in Leptinotarsa decemlineata. At young larval instars, the expression levels of LdTPS were high just before and right after ecdysis, and were low at the mid instar stages. In the fourth-instar larvae, two peaks occurred at 24 h after ecdysis and at the wandering stage. In vitro midgut culture and an in vivo bioassay revealed that 20E stimulated LdTPS transcription. Conversely, a reduction of 20E by RNA interference (RNAi) of a prothoracicotropic hormone receptor gene LdTorso and an ecdysteroidogenesis gene LdSHD repressed LdTPS expression. Moreover, disruption of 20E signaling by knockdown of LdEcR, LdE75 and LdFTZ-F1 reduced LdTPS transcript levels. Similarly, in vitro culture and an in vivo bioassay showed that exogenous JH or JH analog methoprene and pyriproxyfen activated LdTPS expression. An increase in endogenous JH by RNAi of an allatostatin gene LdAS-C enhanced the transcription. In contrast a decrease in JH by silencing of a JH biosynthesis gene LdJHAMT downregulated LdTPS expression. Moreover, knockdown of LdILP2 repressed LdTPS transcription. Therefore, LdTPS transcription is tuned by 20E, JH and ILP signaling pathways in L. decemlineata.
