Cell surface immuno-labeling of epitopes associated with weakly methylesterified homogalacturonan and arabinogalactan proteins using LM19 and LM2, respectively on pollen tubes treated with the compounds for 6 h from 2 biological replicates. White arrow head = pollen tube tip, red arrowhead = ring-like deposit and dashed white line = pollen tube deformation. Scale bar = 40 μm
