Selected defense- and photosynthesis-related proteins identified as modulated in potato leaves submitted to wounding (W) or Colorado potato beetle (CPB) feeding. Bars represent average normalized volumes in 2-D gels ± se; gel samples illustrate protein level alterations after 24 h. Numbers in parentheses refer to protein spot numbers on 2-D gels (see Figure 2). C, control, 'no-stress' treatment; CDI, cathepsin D inhibitor; API-3, aspartic protease inhibitor 3; PDI, protein disulfide isomerase; RbcL fragment, fragment of rubisco large subunit; CPN60-alpha, rubisco subunit-binding protein alpha subunit; RCA, rubisco activase; PsaD, photosystem I reaction center subunit II; PsaE-B, photosystem I reaction center subunit IV B; PsbO, 33-kDa photosystem II oxygen evolving complex protein.
