Figure 2From: Early activation of wheat polyamine biosynthesis during Fusarium head blight implicates putrescine as an inducer of trichothecene mycotoxin productionQuantification of polyamines in wheat heads during Fusarium head blight disease development. Asterisks indicate significant differences (t-test P < 0.05). Error bars are the standard error of the mean. n = 4 individual heads.Back to article page
