Table I. Number of identified protein groups by stage/tissue. Values given in parentheses are the numbers of protein groups when only pollen proteins are considered, which leads to a smaller number of protein groups from the same number of proteins (due to different grouping).

| Microspore | D | 1288 (1264) |
| Polarized microspore | E | 2004 (1956) |
| Binuclear pollen | F | 1770 (1740) |
| Dessicated pollen | G | 1604 (1580) |
| Pollen tubes | H | 2526 (2485) |
| Pollen total | 3888 (3817) | |
| Leaves | 1217 | |
| Roots | 1285 | |
