Figure 5: Differential expression of a plastid Hsp90 (no. 22) and a chloroplast Hsp70 (no. 40) proteins in the shoots (a) and an endoplasmic Hsp90 homologue (no. 118) protein in the roots (b) of the nontransgenic plants (NT), SAG12-ipt line (S41), and HSP18-ipt line (H31) at 10 d of treatment at normal temperature (20°C) or heat stress (35°C) (from [45]).
