Abstract

Despite its critical role in repelling damaging insects, our understanding of nonhost resistance against herbivores remains very limited. Recently, Bai et al. identified a novel caffeoylputrescine-green leaf volatile (GLV) compound in wild tobacco plants that confers nonhost resistance to Empoasca leafhoppers through high-throughput multi-omics analyses.

Keywords: Empoasca decipiens; caffeoylputrescine-green leaf volatile; leafhopper; nonhost resistance; omics.
