The cover shows a confocal microscope image of tobacco protoplasts transiently transformed with a gene cassette containing a signal sequence of a lignin polymerising peroxidase of Norway spruce fused with a GFP sequence, showing the ER- and apoplast-localized lignin polymerising peroxidase (green) that is involved in cell wall formation (see also Shigeto et al., pp. 349–356). Chloroplast auto-fluorescence is shown in red. Photo was taken by Mikko Lehtonen, University of Helsinki.
