Metallothioneins are ubiquitously-expressed metal-binding proteins. Despite their potential ecological relevance, no prior reports have identified any metallothioneins in Ostrinia furnacalis or other Lepidoptera species. A better understanding of the molecular characteristics and regulatory dynamics of metallothionein genes in O. furnacalis under heavy metal stress conditions would enable future studies of the roles played by these proteins in the context of heavy metal detoxification. Herein, we identified and characterized two metallothionein (OfMT) genes in O. furnacalis, including the 147 bp OfMT1 gene encoding a 48 amino acid protein containing 10 cysteine residues, and the 141 bp OfMT2 gene encoding a 46 amino acid protein containing 12 cysteine residues. The expression of OfMT2 was found to be related to Cu and Cd concentrations in a dose-dependent manner but was unaffected by Zn exposure. Overall, these results indicate that OfMT genes likely encode metal-binding proteins consistent with their potential role in the maintenance of heavy metal homeostasis.

This study compared the susceptibility of different triangular silver nanoprisms (TSNPRs) towards the etching of hydrogen peroxide (H2O2), a catalytical product of glucose oxidase (GOx). The influence of capping agents and structural size have been explored towards the oxidation of silver nanoprisms. Results indicated that the etching of the TSNPRs was extremely effected by surface capping agents, in which citrate contributed a highest H2O2-sensitive effect in the absence of secondary capping ligands (e.g., glycerol and ethanol). Meanwhile, compared to bigger TSNPRs, smaller nanoprisms exhibited a different signal output of plasma resonance peak through intensity decrease rather than wavelength shift, making them more H2O2-etching susceptibile. In virtue of GOx etching-based system, TSNPRs with a small size and citrate capping were served as a substitute for big nanoprisms to sense glucose, offering a number of advantages such as high sensitivity, improved calibration, time-saving and extended detection ranges. Moreover, the small sized TSNPRs capping with citrate alone have been expected to be of great interest in the trace of GOx, providing an ultrahigh sensitive GOx etching-based analytical platform for point-of-care diagnostics towards other analytes (e.g., DNA, protein).
