Fig. 2: Categorization of differentially expressed proteins in hybrid Liriodendron after AlCl3 stress.

A Functional classification of proteins that show differential accumulation under AlCl3 stress. B Venn diagram analysis of the differentially accumulated proteins after 30 μM AlCl3 stress; 1 day/control (1D/CK) indicated the differential protein number after 1 day of AlCl3 treatment compared with that under the control condition; 3 day/control (3D/CK) indicates the differential protein number after 3 days of AlCl3 treatment compared with that under the control condition; 5 day/control (5D/CK) indicates the differential protein number after 5 days of AlCl3 treatment compared with that under the control condition; 7 day/control (7D/CK) indicates the differential protein number after 7 days of AlCl3 treatment compared with that under the control condition. C Heat-map clustering of the leaf protein abundance profile under AlCl3 stress. One-week-old hybrid Liriodendron seedlings of somatic embryos were treated with AlCl3 stress for 1, 3, and 7 days. Th seedlings without AlCl3 stress were used as controls. The protein abundance differences between the treatment and control samples were compared by iTRAQ, and different colors represent the differential abundance ratios of proteins between the treatment and control, as depicted in the bar at the bottom of the figure
