Abstract

Capturing the genetic diversity of different wild populations is crucial for unraveling the mechanisms of adaptation and establishing links between genome evolution and local adaptation. The Asian corn borer (ACB) moth has undergone natural selection during its adaptative evolution. However, structural variants (SVs), which play significant roles in these adaptation processes, have not been previously identified. Here, we constructed a multi-assembly graph pan-genome to highlight the importance of SVs in local adaptation. Our analysis revealed that the graph pan-genome contained 176.60 Mb (∼37.33%) of unique sequences. Subsequently, we performed an analysis of expression quantitative trait loci (QTLs) to explore the impact of SVs on gene expression regulation. Notably, through QTL mapping analysis, we identified the FTZ-F1 gene as a potential candidate gene associated with the traits of larval development rate. In sum, we explored the impact of SVs on the local adaptation of pests, therefore facilitating accelerated pest management strategies.

结构变异景观揭示了亚洲玉米螟的地方适应性。
捕捉不同野生种群的遗传多样性对于揭示适应机制和建立基因组进化与当地适应之间的联系至关重要。亚洲玉米螟(ACB)蛾在其适应性进化过程中经历了自然选择。然而,在这些适应过程中发挥重要作用的结构变异(SVs)以前尚未被发现。在这里,我们构建了一个多组装图泛基因组,以突出 SV 在局部适应中的重要性。我们的分析表明,图泛基因组包含 176.60 Mb(37.33%)的独特序列。随后,我们对表达量性状位点(QTLs)进行了分析,以探索 SVs 对基因表达调控的影响。值得注意的是,通过QTL图谱分析,我们发现FTZ-F1基因是与幼虫发育速度性状相关的潜在候选基因。总之,我们探索了 SVs 对害虫本地适应性的影响,从而促进了害虫管理策略的加速。

期刊介绍: Cell Reports publishes high-quality research across the life sciences and focuses on new biological insight as its primary criterion for publication. The journal offers three primary article types: Reports, which are shorter single-point articles, research articles, which are longer and provide deeper mechanistic insights, and resources, which highlight significant technical advances or major informational datasets that contribute to biological advances. Reviews covering recent literature in emerging and active fields are also accepted. The Cell Reports Portfolio includes gold open-access journals that cover life, medical, and physical sciences, and its mission is to make cutting-edge research and methodologies available to a wide readership. The journal's professional in-house editors work closely with authors, reviewers, and the scientific advisory board, which consists of current and future leaders in their respective fields. The advisory board guides the scope, content, and quality of the journal, but editorial decisions are independently made by the in-house scientific editors of Cell Reports.
