Figure 4.

Effect of heat shock at lethal temperature (50°C) on expression of Hsp87 and Hsp85 (A), and Hsp75 and Hsp73 (B) in 24 h-old sorghum seedlings treated for 24 h with CaCl₂, CPZ and LaCl₃. Immunoblotting and densitometric scanning was carried out as described for Figure 1. The data were subjected to one way analysis of variance. (A): significant difference at p ≤ 0.05 with respect to 37°C water-grown control at 51 h. (B): significant difference at p ≤ 0.05 with respect to 50°C water-grown seedlings.
