| 描述信息 |
The tea green leafhopper, Empoasca onukii, is of critical biological and economic interest (Chen, et al. 2019). Despite decades of study and extensive public attention (Fu, et al. 2014), the mechanism underlying its adaptation and evolution remain enigmatic. Here we use previously untapped genome and population genetics approaches to examine how this pest so rapidly adapts to different environmental variables and thus has expanded geographically. We complete a chromosome-level assembly and annotation of the E. onukii genome, showing notable expansions of gene families associated with adaptation to chemoreception and detoxification. Genomic signals indicating balancing selection highlight metabolic pathways involved in adaptation to a wide range of tea varieties grown across ecologically diverse regions. Patterns of genetic variation among 57 55 E. onukii samples unveil the evolutionary history and potential dispersal routes across different tea-growing regions in China. Our results demonstrate that the genomic change in key pathways, including those linked to metabolism, circadian rhythms and immune system function, may underlie the successful spread and adaptation of E. onukii. This work highlights the genetic and molecular bases underlying the evolutionary success of a species with broad economic impact, and provides insight into insect adaptation to host plants, which will ultimately facilitate more sustainable pest management. |
