Accumulation of trans-piceid in sorghum seedlings infected with Colletotrichum sublineolum

Using LC-MS in precursor ion scan mode, trans-piceid was identified as the major stilbene metabolite in sorghum seedlings infected with the anthracnose pathogen Colletotrichum sublineolum. However, trans-piceid alone may not be a significant defense component against this pathogen. This is the first report of stilbene accumulation in sorghum.
