Insect egg-killing: a new front on the evolutionary arms-race between brassicaceous plants and pierid butterflies

A novel front-line of plant defence is the killing of herbivorous insect eggs with an HR reponse. We test whether this HR-based egg-killing plant trait has an evolutionary basis in the plant–insect arms-race. We studied the phylogenetic distribution of this trait, its egg-killing effect on and elicitation by butterflies, by screening 31 Brassicales species, and nine Pieridae species.<br><br>This dataset is part of Chapter 2 of the PhD thesis "E(gg)xit strategy of plant defense: Evolution and genetics of a butterfly egg-triggered cell death"植物防御的一条全新前沿防线，是通过超敏反应（Hypersensitive Response, HR）杀灭植食性昆虫卵。本研究旨在验证这种基于超敏反应的杀卵植物性状，是否在植物-昆虫军备竞赛中具备进化基础。我们通过筛选31个十字花目（Brassicales）物种与9个粉蝶科（Pieridae）物种，研究了该性状的系统发育分布、其对蝶类的杀卵效应，以及蝶类对该性状的诱导作用。 本数据集属于博士学位论文《植物防御的E(gg)xit策略：蝶卵触发的细胞死亡的进化与遗传机制》的第2章内容。
