28甘蓝型油菜品系的发展，具有对比的叶硫代葡萄糖苷的配置文件中发现的商业油菜品种。这些品系在脂肪族硫代葡萄糖苷的总量和不同侧链结构的比例上都不同。在田间试验中使用的线路，以评估芥子油苷介导的方式之间的相互作用的拟南芥和专业害虫（Psylliodes chrysocephala和粉蝶）和通才害虫（鸽子和蛞蝓）。芥子油苷水平的增加导致成年跳蚤甲虫（P. chrysocephala）造成更大的损害，并导致粉蝶幼虫的发病率更高，但减少了鸽子和蛞蝓的放牧程度。减少脂肪族硫代葡萄糖苷侧链长度和减少丁烯基硫代葡萄糖苷羟基化程度增加了成虫取食的程度。修改的油菜叶片的硫代葡萄糖苷含量的影响和植物/草食动物相互作用中的作用，这些次生代谢产物进行了讨论。
Twenty eight Brassica napus lines were developed which had contrasting leaf glucosinolate profiles to those found in commercial oilseed rape cultivars. The lines varied both in the total amount of aliphatic glucosinolates and in the ratio of different side chain structures. The lines were used in field experiments to assess the manner by which glucosinolates mediate the interactions between Brasssica and specialist pests (Psylliodes chrysocephala and Pieris rapae) and generalist pests (pigeons and slugs). Increases in the level of glucosinolates resulted in greater damage by adult flea beetles (P. chrysocephala) and a greater incidence of Pieris rapae larvae, but reduced the extent of grazing by pigeons and slugs. Decreasing the side chain length of aliphatic glucosinolates and reducing the extent of hydroxylation of butenyl glucosinolates increased the extent of adult flea beetle feeding. The implications of modifying the glucosinolate content of the leaves of oilseed rape and the role of these secondary metabolites in plant/herbivore interactions are discussed.
