MS/MS spectral tag (MS2T) libraries are collections of phytochemical MS2 spectral data obtained by using an automatic MS2 acquistion function of LC-ESI-Q-TOF/MS (Waters Aquity Q-TOF). The basic concept of MS2T and its application for metabolite annotation are explained in Matsuda et al (2008) Plant J 57: 555-77. Now, total 1,623,091 MS2T data derived from Arabidopsis, rice, wheat, and soybean are available.
