The identification of proteins involved in pollen germination and tube growth is important for fundamental studies of fertility and reproduction in flowering plants. We used 2-DE and MALDI-TOF-MS to identify differentially expressed proteins in mature (P0) and 1-h germinated (P1) maize pollen. Among about 470 proteins separated in 2D gels, the abundances of 26 protein spots changed (up- or down-regulation)...
