PEEKING INTO PIT FIELDS
Plasmodesmata (PD), the small pores that connect plant cells, are difficult to image by conventional microscopy methods. In this issue, Faulkner et al. (pages 1504–1518) describe a freeze fracturing protocol that exposes PD in surface views of the cell wall. The cover image shows a confocal laser scanning microscopy view of the fractured basal wall of a leaf trichome cell. PD within the radially extending pit fields are labeled with a tobacco mosaic virus movement-GFP fusion (green), while the cell wall has been stained with the cellulose-specific probe Calcofluor (blue).
