在与害虫的无声较量中，人类正面临着一场前所未有的智慧博弈。当传统农药逐渐失效，绿色防控技术 亟待突破，破译害虫的基因密码成了获胜的关键所在。 高质量的基因组图谱，如同一张"地图"，为开发新的绿色防治手段，靶标的精准发现与定位提供了关键 指引。然而，如何绘制一张准确、完整的"地图"？这场关乎生态平衡的攻防战，科研人员找到了破局之 道。 科研团队提出了一种新的组装策略。他们以单个体雄虫的测序数据作为基本骨架，整合群体测序数据， 利用不同的测序技术相互补充。 这是一个不同寻常的选择。 论文共同第一作者、中国农业科学院深圳农业基因组研究所副研究员林强说，在以往的研究中，由于技 术限制，科研人员常常需要将不同个体昆虫混合在一起，以达到传统测序所需的DNA量。有时，为了 降低分析难度，会特意选择遗传背景更简单的雌虫。但这就像把许多张相似但不完全一样的地图碎片混 在一起拼图，最终拼出的地图会充满重叠的"重影"，模糊不清。 "更重要的是，这种方法会完全丢失只有雄虫才拥有的Y染色体地图，而这部分信息对于理解雄性发育 和开发针对雄虫的防控技术至关重要。"林强说。 12月3日，中国农业科学院深圳农业基因组研究所研究员王桂荣课题组联 ...
