    • Changes in hydroxamic acid levels of wheat plants induced by aphid feeding 
      Niemeyer, Hermann M.; Pesel, Erika; Copaja, Sylvia V.; Bravo, Héctor R.; Franke, Stephan; Francke, Wittko (1989)
      Seedlings of four wheat cultivars were infested with Metopolophium dirhodum nymphs. After aphids had fed for 40 hr on the plants, the levels of the defense metabolite 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one had changed. ...
