  1. DMNT, (3E)-4,8-di-methyl-1,3,7-nonatriene; Ret. time, retention time.
  2. Maize, cotton and cowpea plants were exposed to synthetic indole for 12 h and then wounded and treated with S. littoralis regurgitant. Volatiles were collected every 90 min between 180 and 630 min following induction. After automated alignment and feature detection, internal standard signal intensity and plant weight correction, the intensities of the different features were summed up for statistical analysis. Differentially regulated features are shown (n=3–4, Student’s t-test, P<0.05).
