Figure 9From: Transcriptional analysis of cell growth and morphogenesis in the unicellular green alga Micrasterias(Streptophyta), with emphasis on the role of expansinImmunogold labelling with anti-GFP antibody of high pressure-freeze fixed Micrasterias denticulata interphase cells. (A) and (B) Positive signal present in the secondary cell wall (arrows) and absent from the cytoplasm in MdEXP2-GFP-overexpressing cells. Detachment of the wall from the cytoplasm is a preparation artefact. (C) and (D) Label present in the cytoplasm and absent from the cell wall in cells overproducing the free GFP. (D) Inset of (C). SW, Secondary cell wall. Scale bar = 1 μm (A, B, D) and 2 μm (C).Back to article page
