Comparative Physiological and Proteomic Analyses of Poplar (Populus yunnanensis) Plantlets Exposed to High Temperature and Drought (original) (raw)
Figure 3
Accumulation of proline, malondialdehyde (MDA), and reactive oxygen species (ROS) (H2O2 and O2−) in Populus yunnanensis plantlets after different durations of exposure to different stresses.
(A) Proline content at different times under heat, drought, or combined heat and drought. (B) MDA content at different times under heat, drought, or combined heat and drought. Data (B and C) represent the means of five replicate experiments (± SE). Means labeled by different letters were significantly different according to Tukey's test (P<0.05). (C) In situ detection of changes in leaf H2O2 levels at different times under heat, drought, or their combination. (D) In situ detection of changes in leaf O2− levels at different times under heat, drought, or combined heat and drought.
