Through evolution, some plants have developed natural resistance to insects by having hairs (trichomes) on leaves and other tissues. The hairy trait has been neglected in Brassica breeding programs, which mainly focus on disease resistance, yield, and overall crop productivity. | Hairy Canola Brasssica napus re-visited Down-regulating TTG1 in an AtGL3- enhanced hairy leaf background improves growth leaf trichome coverage and metabolite gene expression diversity
