Fig. 2From: Glycolysis stimulation and storage protein accumulation are hallmarks of maize (Zea mays L.) grain filling2-DE analysis of proteins extracted from the kernels of the purple maize cultivar ‘Heukjinjuchal’ at 15, 20, 25, and 30 days after pollination (DAP). Differentially accumulated protein spots are indicated by arrows and numbered (see Table 1 for description of a subset of the corresponding proteins). IEF indicates the isoelectric focusing dimension (pI 4–7)Back to article page
