Figure 3. Comparative proteome analysis of laser-grown Arabidopsis plants.
(a) Functional classification of differentially expressed Arabidopsis proteins in response to single-wavelength red and blue lasers light. Total soluble proteins were extracted from Arabidopsis plantlets treated under a continuous laser light for 7 days with average photon flux density of 90–100 μmol m−2 s−1. Protein extraction was done with tricarboxylic acid (TCA) precipitation prior to iTRAQ labeling for liquid chromatography-tandem mass spectrometry (LC-MS/MS). Proteins that have P value of ≤ 0.05 and fold change of Ι1.5Ι were considered as differentially expressed (see Methods for data analysis).
