Fig 6Fluorescent immunolabeling of pectins in a Picea wilsonii pollen tube.

(A) JIM5 labeling of pollen tubes cultured in standard medium. Strong fluorescence was detected along the entire tube shank wall, excluding the tip. (B) JIM7 labeling of pollen tubes cultured in standard medium. Esterified pectins were found at the tip of the pollen tube. (C) JIM5 labeling of pollen tubes treated with medium containing 0.2% DMSO. The result is consistent with that obtained for the control (A). (D) JIM7 labeling of pollen tubes treated with medium containing 0.2% DMSO. The distribution of esterified pectins is consistent with that seen in the control (B). (E) JIM5 labeling of pollen tubes cultured in the presence of 0.5 μM TSA. The fluorescence signal was distributed along the pollen tube wall. (F) JIM7 labeling of pollen tubes incubated in medium containing 0.5 μM TSA. Esterified pectins were found only in the basal part of the pollen tube wall. (G) JIM5 labeling of pollen tubes cultured in the presence of 0.5 mM NaB. (H) JIM7 labeling of pollen tubes incubated in medium containing 0.5 mM NaB. Bar = 50 μm.

Figure 1Effects of DCB on pollen germination and pollen tube growth of Pinus bungeana Zucc.

Bars = 60 µm (A, B, C), 20 µm (F, G). A. The control pollen tube growing in 1% ethanol, showing normal length and shape. B. Pollen tubes cultured in normal medium for 3 d, showing normal shape and long tube. C. Pollen tubes treated with 10⁻¹µM DCB for 3 d, the tip and /or the base of pollen tube swelled. D. DCB slightly affected germination percentage of pollen grains of Pinus bungeana. Only pollen tubes that were longer than the diameter of pollen grain were measured. Mean values are shown with SD of three experiments. E. DCB inhibited the pollen tube growth of Pinus bungeana. Only pollen tubes that were longer than the diameter of pollen grain were measured. Mean values are shown with SD of three experiments. F. Pollen tubes cultured in normal medium for 3 d, showing normal shape. G. Pollen tubes cultured in normal medium for 3 d and then treated with DCB for 6 h, showing the tube tip ruptured (arrow).
