Figure 1From: The broccoli (Brassica oleracea) phloem tissue proteomePhloem-enriched strands isolated from Brassica oleracea. (A) Brightfield micrograph of the phloem-enriched strands showing numerous sieve plates (arrows) (bar = 200 μm). (B-C) Immunolocalization of sieve elements within the phloem-enriched strands, containing phloem-specific protein antigens for monoclonal antibodies that recognize the (B) SE-ENOD and (C) SE-specific p35 protein (bar = 100 μm).Back to article page
