Figure 5From: Thaumatin-like proteins are differentially expressed and localized in phloem tissues of hybrid poplarLongitudinal sections of phloem parenchyma cells (PP) and phloem fibres (PF) in mature stem labeled with TLP1 antiserum. Panels A-C show bright field images and panels D-F the corresponding immunofluorescent images. The stem section in panel D was treated without the primary antibody, E was treated with preimmune serum, and F was treated with TLP1 antiserum. Arrows indicate position of labeled phloem parenchyma cells. Scale bar = 20 μm.Back to article page
