Figure 5. Integrative view of protein-protein interactions and coexpression networks of AT3G46230 (orthologous gene of sHsp17.5 in barley) derived in Arabidopsis based on CORNET correlation networks [20].

Predicted protein interactions are highlighted in dotted black colour and also autoregulatory loops are shown for several Hsp proteins. The embedded coexpression network of AT3G46230 includes several direct and indirect targets identified through microarray experiments from 256 experimental data sets generated from abiotic stress treatments. Significance of coexpression is measured by the Pearson correlation coefficient (dark blue lines represent positive correlation of 0.9; light blue lines represent positive correlation of 0.8).
