Fig. 1.

Multiple sequence alignment of wheat Hsp16.9 (TaHsp16.9), rice Hsp16.9, Hsp18.6, Hsp26.7, Hsp24 and peroxisome-Hsp16. Chloroplast transit peptide of Hsp26.7 and mitochondria signal peptide of Hsp24 are shown in green, nuclear localisation signal of Hsp18.6 in red, peroxisome-targeting signal of peroxisome-Hsp16 in blue and methionine-rich motif of Hsp26.7 in orange. Conserved residues/motifs are shown in coloured boxes: green—PG doublet, purple—conserved arginine, pink—IXI motif. Black arrowheads delineate the ACD of TaHsp16.9. Residues of wheat Hsp16.9 which mediate intra-dimer (blue dot) and inter-dimer (red dot) interactions are indicated
