Figure 1. Isolated rice gametes and comparison of protein extracts from rice egg cells, sperm cells, callus, seedlings, and pollen grains.

Figure 1

(A) Isolated egg cells. (B) Isolated sperm cells fraction. Black and white arrowheads indicate typical sperm cells and cell debris, respectively. (C) Lysates from 50 egg cells, 3,000 sperm cells, callus (0.1 µg protein), seedlings (0.12 µg protein), and pollen grains (0.06 µg protein) were separated by SDS-PAGE and conventionally silver stained. Bars = 50 µm.
