Figure 2From: Wounding, insect chewing and phloem sap feeding differentially alter the leaf proteome of potato, Solanum tuberosum L. Gel image for the proteome of potato leaves submitted to potato aphid phloem sap feeding, as visualized after Coomassie blue staining following 2-DE. Protein spot numbers point to proteins up- or downregulated following mechanical wounding, Colorado potato beetle leaf chewing or potato aphid feeding. A non-linear 3 to 10 pI gradient was used for IEF. Mr values on the left refer to commercial molecular weight protein markers (kDa). A total of 167 μg of protein was loaded on each 2-D gel. Proteins synthesized de novo upon wounding or potato beetle chewing are not shown on this gel.Back to article page
