| 1 | Phylogenetic Analysis and Molecular Identification of the Six Reticulitermes Species Using Different Markers显示文摘The tennite genus Reticulitermes species are serious pests of wooden structures and important quarantine insects in the world. It is very difficult to distinguish different Reticulitermes species based on their similar morphology, which brings much trouble to quarantine work for invasive Reticulitermes species. Here, we used the four molecular markers, 18 S rDNA, COI, COII and ITS genes, to carry out phylogenetic analysis and identification of the six Reticulitermes species. We found that R. labralis, R. speratus, R. aculabialis, R. chinensis and R.flaviceps from China clustered together in the phylogenetic tree of COI gene, consisting with geographical distribution of them. We suggest that COI gene is suitable for interspecific phylogenetic analysis of Reticulitermes species. Subsequently, we designed and synthesized specific primer and TaqMan probe based on the COI gene of R. chinensis, and found that this primer can specifically detect R. chinensis. The minimum concentration of DNA sample is lpg/μL for the identification of R. chinensis. Our results suggest that the rapid and accurate identification of different Reticulitermes species can be achieved by fluorescent PCR technology based on COI gene. | Du Danni Guan Junxia Sun Pengdong Wang Zhenhua Huang Qiuying | 2018 | 华中昆虫研究2018，，1： | 0 |
| 2 | A non-rigid shift of band dispersions induced by Cu intercalation in 2H-TaSe2显示文摘The intercalation of metal is a promising method for the modulating electronic properties in transition metal dichalcogenides(TMDs).However,there still lacks enough knowledge about how the intercalated atoms directly impact the two-dimensional structural layers and modulate the band structures therein.Taking advantage of X-ray absorption fine structure and angle-resolved photoemission spectroscopy,we studied how Cu intercalation influences the host TaSe2 layers in Cu0.03TaSe2 crystals.The intercalated Cu atoms form bonds with Se of the host layers,and there is charge transfer from Cu to Se.By examining the changes of band dispersions,we show that the variation of electronic structures is beyond a simple rigid band model with merely charge doping effect.This work'reveals that the unusual change of band dispersions is associated with the formation of bonds between the intercalated metal elements and anion ions in the host layers,and provides a reference for the comprehensive understanding of the electronic structures in intercalated materials. | Pengdong Wang Rashid Khan Zhanfeng Liu Bo Zhang Yuliang Li Sheng Wang Yunbo Wu Hongen Zhu Yi Liu Guobin Zhang Dayong Liu Shuangming Chen Li Song Zhe Sun | 2020 | Nano Research2020，13，2： | 0 |
