6Insights into the mechanism of shortened developmental duration and accelerated weight gain associated with Wolbachia infection in Hylyphantes graminicola显示文摘Wolbachia infection is known to affect host reproduction and development.To date,however,the underlying mechanism related to the effects of Wolbachia on host development has not yet been reported.Here,we compared the developmental duration and body weight in different instars of Wolbachia-positive(W+)and Wolbachia-negative(W−)spiders(Hylyphantes graminicola)and detected the relative expression levels of 6 insulin-related genes and 3 ecdysone-related genes using reverse transcription qPCR.Results showed that the developmental duration was significantly shortened in W+spiders compared with W−spiders.Furthermore,W+spiders were significantly heavier thanW−spiders at the 3rd and 4th instars,although no significant differences in body weight were observed after maturity.We also found that the expression levels of insulin-like growth factor-2 mRNA-binding protein-1,insulin-degrading enzyme,and ecdysone-inducible protein-1 genes were significantly down-regulated in W+spiders compared with W−spiders,whereas the expression levels of insulin-like growth factor-binding protein-1,insulin-like peptide receptor,insulin receptor substrate 2-B,insulin-like,ecdysone-induced protein-2,and ecdysone receptor genes were significantly up-regulated inW+spiders.Our results suggest thatWolbachia may influence host development by affecting insulin and ecdysone signaling pathways.Chunfen LI Meng HE Yinjie CUI Yu PENG Jie LIU Yueli YUN 2022Integrative Zoology2022,17,3:0
7Ru-based catalysts for efficient CO_(2) methanation:Synergistic catalysis between oxygen vacancies and basic sites显示文摘The fundamental insights of the reaction mechanism,especially the synergistic effect between oxygen vacancies and basic sites,are highly promising yet challenging for Ru-based catalysts during carbon dioxide(CO_(2))methanation.Herein,a series of Rubased catalysts were employed to study the mechanism of CO_(2) methanation.It is found that Ru/CeO_(2) catalyst exhibits a much higher CO_(2) conversion(86%)and CH4 selectivity(100%),as well as excellent stability of 30 h due to the existence of abundant oxygen vacancies and weak basic sites.Additionally,the in-situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS)and density functional theory(DFT)calculations reveal that the formate formation step dominated the hydrogenation route on Ru/CeO_(2) catalyst,and the b-HCOO^(*)could be the key intermediate due to b-HCOO^(*)is more easily hydrogenated to methane than m-HCOO^(*).The systematic study marks the significance of precise tailoring of the synergistic relationship between oxygen vacancies and basic sites for achieving the desired performance in CO_(2) methanation.Chunfen Wang Yonglian Lu Yu Zhang Hui Fu Shuzhuang Sun Feng Li Zhiyao Duan Zhen Liu Chunfei Wu Youhe Wang Hongman Sun Zifeng Yan 2023Nano Research2023,16,10:0
