Fig. 7

MALDI-TOF MS spectra from triplicate sample preparations of Impatiens glandulifera-leaf acid-soluble proteins extracted from fresh leaf material at t = 0 (a–c), and untreated leaf material after storage for 35 days at − 20 °C (d–f), 5 °C (g–i), 20 °C (j–l), 30 °C (m–o), and 40 °C (p–r). Spectra are shown baseline-subtracted, smoothed, y-axis-autoscaled, and covering the mass range 2–20 kDa (with x-axis scale increments of 2 kDa)
