Figure 3From: Rapid metabolic profiling of Nicotiana tabacum defence responses against Phytophthora nicotianae using direct infrared laser desorption ionization mass spectrometry and principal component analysisQuantitative LC-ESI MS/MS analysis of phytohormones (time-profiles). Absolute amount of the major signaling phytohormones (ABA, JA, and SA) per weight of fresh leave material in two different cultivars of Tobacco (SNN, and Xanthi), determined by LC-ESI MS/MS in multiple reaction mode (MRM). Samples labeled with a preceding "X*" represent samples from N. tabacum (cv. Xanthi), * represents the sample treatment (for detailed explanation of the nomenclature employed, see text).Back to article page
