Protein networks built with the sHSPs and HSPs that are up-regulated (i.e. overexpressed) as a response to heat stress treatment. (a) Heat stress induced in wild type (WT) tomato plants (where HsfA2 is present); (b) heat stress induced in tomato protoplasts (where HsfA2 was inhibited using RNAi). The two networks correspond to the two conditions tested: i.e., (c) tomato plants in the presence of HsfA2 (blue label) and (d) tomato protoplasts in the absence of HsfA2 (red label). In the networks: nodes are proteins and edges interactions. The proteins included in the networks were HSPs, sHSPs and related proteins up-regulated after heat stress: HSP70-90-100s (yellow nodes), sHSPs (blue nodes) and other heat stress related proteins (light yellow nodes). Colored labels indicate specific proteins dependent on the presence (blue) or absence (red) of HsfA2. The interactions were derived from the known functional or physical associations between proteins
