Understanding Heat Stress Tolerance of Suspended Cells in the Model Plant Populus euphratica

Figure 1

P. euphratica cell viability after 20 min exposure to different temperatures (5 to 75°C). Cell viability was determined by the trypan blue exclusion method immediately before heat treatment (⬤), after recovery at 25°C for 10 min (○) and for 20 h (♦). Results represented mean values of twenty independent cell counts (>50 cells per count).
