Study of Flowering Pattern in Setaria viridis, a Proposed Model Species for C4 Photosynthesis Research

Figure 3

The time-lapse images of opening and closing of a spikelet are shown for every 30 minutes. In the first 75 minutes, the lemma and glume of the spikelet are pushed aside from inside. Then, the stigma emerges, followed by the anthers which elongate taller than stigma. The anthers dehisce and collapse on the stigma, and then, the spikelet closes. The remains of shed pollen and desiccated anther leave brown vestiges on the tip of the spikelet. The details of opening, pollination, and closing of a single spikelet are shown in the video in Supplementary Material 2.
