Figure 4

Refilling of embolized fibers due to changes in lighting conditions. XMT images showing refilling of embolized wood fibers in the shoot tip of a young Silver birch (sample B). a) Image taken immediately after excision in the afternoon, and b) the same tissue after maintaining the sample in darkness for one hour. To guide the eye, the white arrows point to the same sclereids in both images. Green arrows indicate areas where refilling of fibers occurred between the scans. Scale bars 350 μm. The single embolized vessel observed in the sample is near the upper-right corner of the images (red arrow).
