Figure 8From: Pectic homogalacturonan masks abundant sets of xyloglucan epitopes in plant cell wallsIndirect immunofluorescence detection of xyloglucan and pectic HG epitopes in TS tobacco stem internode showing higher magnification micrographs of region of cortical collenchyma/parenchyma. a. LM15 binding to cell walls after pectate lyase pretreatment is most strong at outer regions adjacent to middle lamellae. b. Same section as a shown combined with Calcofluor White fluorescence. c. Equivalent section to a immunolabelled with JIM5 showing HG across cell walls and abundance at inner cell walls and intercellular spaces of parenchyma (bottom of micrograph). d. Same section as c shown combined with Calcofluor White fluorescence. Arrows in a and b indicate outer cell wall regions adjacent to middle lamellae with abundant LM15 epitope. Arrows in c and d indicate inner edge of cell walls and abundant JIM5 epitope. Double headed arrows indicate intercellular spaces. Scale = 10 μm.Back to article page
