Microbiome . . . Professor Hong Xiaoyue's team at Nannon Plant Protection College has revealed the mechanism by which invading Wolbach bacteria alters the gray fly lice microbiome!

On July 2, 2020, microbiome, an international authoritative journal in the field of Microbiology, published online the latest research result of Hong Xiaoyue, laboratory of insect molecular ecology and evolution, School of plant protection, Nanjing Agricultural University.insects contain a large and complex microbial society. After long-term coevolution, they have formed countless ties with their hosts and play an important role in host growth, development, reproduction and external environment adaptation.in recent years, more and more attention has been paid to the influence of microorganisms on insects, but the factors affecting the social structure of microorganisms are still largely unknown.from the perspective of population genetics, this paper studied the relationship between the variation of microbial community structure and environmental factors and host genetic background of 17 geographic populations of the brown planthopper in China and Japan, and revealed that the precipitation and mitochondrial DNA variation in the habitats of the brown planthopper could significantly affect the microbial community structure in vivo.further analysis showed that the infection of Wolbachia (Wolbachia) and its rapid spread in the population of Laodelphax striatellus have completely changed the microbial community structure in the Laodelphax striatellus, and reshaped the interaction between microorganisms. It is suggested that Wolbachia may affect the biological characteristics of the Laodelphax by changing the microbial community structure.comparative transcriptome analysis showed that Wolbachia in Laodelphax striatellus could inhibit the diversity and abundance of microbial community by affecting the metabolism and physiology of insects.this study revealed the potential factors affecting the microbial community of the brown planthopper, provided a new idea for the study of the formation mechanism of insect microbial community, and had an important reference value for the study of the impact of microorganisms on insects.taking Nanjing Agricultural University as the first completed unit, Duan Xingzhi, Associate Professor Sun Jingtao and Associate Professor Duan Xingzhi, Department of Entomology, School of plant protection, Nanjing Agricultural University are the co first authors, and Professor Hong Xiaoyue is the corresponding author.Professor ary Hoffmann, University of Melbourne, Australia, Dr. Li Jie, Hokkaido University, Japan, and researcher Keiichiro Matsumura of the Kyushu Okinawa agricultural research center of the Japanese National Agricultural Research Institute (Naro) have also made important contributions to this work. Wang linting, Shu Xiaohan, Guo Yan and other graduate students from the Insect Molecular Ecology Laboratory of Nanjing Agricultural University participated in part of the work.the research was supported by the National Natural Science Foundation of China.in recent years, Professor Hong Xiaoyue's team has published a number of important research papers in the field of insect molecular ecology, which is another masterpiece after the papers in the ISME journal, new physiology, molecular ecology, MPE and other important academic journals, further enhancing the team's academic influence in this field.paper link: plant biotechnology PBJ communication group in order to more effectively help the majority of scientific research workers to obtain relevant information, plant biotechnology PBJ established a wechat group, plant biotechnology Journal submission and literature related issues, official account number and official account submission will be focused on solving problems in the group, and encourage academic exchanges and academic thinking in the group.in order to ensure a good discussion environment in the group, please add a small wechat first, scan the QR code to add, and then we will invite you to join the group in time.tip: when adding small wechat and after joining the group, please make sure to note the name of the school or unit + at the end of the PI, and we will invite you to join the Pi group.
