Infection markers identified in leaves of the apoplast of Arabidopsis thaliana infected with Verticillium longisporum VL43.

AWF was obtained from A. thaliana leaves 21 days post infection and analyzed by UPLC-TOF-MS. Data are means of 3 biological and 3 technical replicates. SI = Signal intensity, Mode of identification refers to A) Exact mass measurement, B) retention time (RT) comparison to authentic standards, C) UV/VIS spectrum, and D) MS/MS fragmentation. P-values were calculated by Students t-test.
