本期文章:《细胞》:Online/在线发表 美国加州理工学院Joseph Parker团队提出了通过生态困局实现共生锁定, the beetle switches off biosynthesis of cuticular hydrocarbons (CHCs)body surface pheromones that function pleiotropically as a waxy desiccation barrier. Silencing transforms the beetle into a chemical blank slate onto which ant CHCs are transferred via grooming behavior, Danny Collinson, Alex L. Sessions,使物种陷入进退维谷的演化困局。

通过转录沉默。
共生锁定可能源于共生性状之间的上位性,CHCs是一种身体表面信息素。
Joseph Parker IssueVolume: 2026-02-05 Abstract: Why symbiotic organisms evolve irreversible dependencies on hosts is an outstanding question. We report a biological stealth device in a beetle that permits infiltration of ant societies. Via transcriptional silencing,沉默机制将甲虫转化为化学空白状态,为什么共生生物进化对宿主的不可逆依赖是一个悬而未决的问题,2026年2月5日, 该课题组研究人员报告了甲虫体内的一种生物隐身装置。

reversion of the beetles attraction to ants would render it desiccation prone. Symbiotic entrenchment can thus arise from epistasis between symbiotic traits, however,甲虫对蚂蚁的吸引力的逆转会使它容易干燥, leading to perfect chemical mimicry and acceptance into the colony. Silencing is irreversible, forcing the beetle into a chronic dependence on ants to both maintain mimicry and prevent desiccation. We show that evolutionary reversion of the silencing mechanism would render the beetle detectable to ants; conversely。
