The pollen tube, a fast tip-growing cell, is an excellent model to study membrane and cell wall biosynthesis. Here, we describe a simple protocol using an easy to use device to perform immunofluorescence labelling of pollen tube membrane and cell wall. The use of the NucleoSpin column to perform all the steps of the immunolabelling procedure results in obtaining more intact pollen tubes.

[Abstract] The pollen tube, a fast tip-growing cell, is an excellent model to study membrane and cell wall biosynthesis. Here, we describe a simple protocol using an easy to use device to perform immunofluorescence labelling of pollen tube membrane and cell wall. The use of the NucleoSpin column to perform all the steps of the immunolabelling procedure results in obtaining more intact pollen tubes.

  5. Microcentrifuge (VWRTM Galaxy 14D)

Procedure

  1. In vitro Arabidopsis pollen tube growth and fixation
    Note: See also the protocol available at Li (2011). However we advice to use the conditions detailed in the following protocol (number of flowers, PGM volume, temperature) to enhance the reproducibility.
    1. Grow Arabidopsis pollen in vitro according to the method described by Boavida and McCormick (2007).
      1. Harvest 40 freshly open Arabidopsis thaliana flowers (morning is the best) using a pair of tweezers.
      2. Submerge in 1 ml of PGM in a 1.5 ml Eppendorf tube.
      3. Shake the tube vigorously manually and with a vortex for 5 min to release the pollen grains from the anthers.
      4. Check the pollen number density with an inverted microscope.
      5. Remove all the flower debris with a pair of tweezers.
      6. Spin-down the pollen suspension using the microcentrifuge at 3,200 x g for 7 min (a yellowish pellet should be visible).
      7. Remove the supernatant by pipetting.
      8. Add 250 µl of PGM and resuspend the pellet.
      9. Place the tube horizontally in the incubator at 22 °C in the dark for 6 h.
      10. After 6 h, check for pollen germination and pollen tube growth with the inverted microscope (Figure 1).


        Figure 1. 6 h-old Arabidopsis pollen tubes. Note that the pollen grain density is important to obtain good pollen germination rates.

  2. Pollen tube fixation and immunolabelling
    Note: The protocol described below is adapted from Botté et al. (2011) and Dumont et al. (2014) for pollen membrane and pollen cell wall labelling respectively. Medium can be removed either by aspiration by connecting the NucleoSpin® Plasmid Binding Column to a vacuum such as a water aspirator (Figure 2) or by centrifugation at 300 x g for 1 min in a microcentrifuge. In the aspiration method, the flow-through is discarded and the germinated pollens present on the silica membrane are gently resuspended in the appropriate buffer. Although very similar the two protocols differ with an additional permeabilization step for pollen tube membrane labelling (step B4) and the use of different buffers (Figure 4). Buffers used for the cell wall labelling (Dumont et al., 2014) are written between parentheses.


    Figure 2. NucleoSpin® Plasmid Binding Columns connected to a hose for aspiration

    1. Pollen tubes in PGM were mixed (v/v) with a fixation medium containing 5% methanol-free formaldehyde in TBS buffer (or 5% formaldehyde in the fixation solution). Pollen tubes are incubated overnight at 4 °C before use (do not store the pollen tubes longer than 1 month).
    2. Transfer the pollen tubes solution on a NucleoSpin® Plasmid Binding Column held on a collection tube, under the fumehood.
      Note: All transfer and all washing steps described below are performed with a tip cut 0.5 cm from its extremity to avoid pollen tube damages (such ready to use wide bore pipet tips are available here: http://www.thomassci.com/Supplies/Pipettor-Tips/_/200l-Clear-Wide-Bore-Pipet-Tips?q=Wide%20Tip%20Pipet or http://catalog2.corning.com/LifeSciences/en-US/Shopping/ProductDetails.aspx?productid=T-205-WB-C%28Lifesciences%29&categoryname=).
    3. Remove the medium by aspiration or centrifugation and wash three times with 100 µl TBS buffer (or CMF-DPBS, both filtered at 0.22 µm using a syringe filter). Pollen tubes are gently resuspended in the buffer by pipetting up and down and the buffer is removed by aspiration/centrifugation.
    4. Seal the bottom of the column with parafilm® and add 100 µl 0.002% saponin in TBS for 15 min for pollen membrane permeabilization (skip this step and the next one for the cell wall immunolabelling).
    5. Remove the medium by aspiration/centrifugation.
    6. Seal the bottom of the column with parafilm® and incubate the pollen tubes with 100 µl blocking buffer 1 (or blocking buffer 2), freshly prepared, for 1 h.
    7. Remove the blocking buffer by aspiration/centrifugation.
    8. The cell wall labelling requires three washes with CMF-DPBS as explained in step B3 (Skip this step for the membrane immunolabelling).
    9. Seal the bottom of the column and add 50 µl of primary antibody 1:10 dilution DGDG-specific rabbit serum in TBS-1%FBS-0.002% saponin and incubate 1 h at room temperature (or for the cell wall labelling: 1:20 primary antibody in CMF-DPBS overnight at 4 °C). Negative controls are prepared by omitting the primary antibody.
    10. Wash three times with TBS-1% FBS-0.002% saponin (or CMF-DPBS) as explained in step B3.
    11. Seal the bottom of the column and add 50 µl 1:500 dilution Alexa secondary antibody in TBS-1%FBS-0.002% saponin and incubate 1 h at room temperature (or for the cell wall labelling: FITC-coupled secondary antibody 1:50 dilution in CMF-DPBS for 2 h at 30 °C).
      Note: From this step, keep the tubes in the dark in aluminum foil.
    12. Wash four times in TBS-1% FBS-0.002% saponin and a final wash with TBS (or five times with CMF-DPBS) as explained in step B3.
    13. In order to recover the pollen tubes, resuspend them by adding at the top of the column 100 µl of TBS (or water) and by pipetting up and down several times with an enlarged tip and transfer the solution which contains the pollen tubes on a microscope slide with a cover slip. Figure 3 shows the confocal images showing the results of immunofluorescence labelling of Arabidopsis pollen tubes with anti-DGDG. Figure 4 gives an overview of the method for the membrane or cell wall immunolabelling of pollen tubes.


      Figure 3. Arabidopsis pollen grains were germinated for 6 h, pollen tubes were fixed and the pollen tube membrane immunolabelled with anti-DGDG antibodies. Alexa 488 was excited using the 488 nm line of an argon laser and fluorescence was collected between 500-539 nm. Superposition of control red autofluorescence induced by excitation at 543 nm laser is also shown.


      Figure 4. Schematic representation of the sample preparation for Arabidopsis pollen tubes plasma membrane and cell wall immunolabelling. Green dashed box indicates special step or buffer for plasma membrane labelling whereas blue dashed box points out the steps for the cell wall labelling. The picture at the bottom of the image shows a pollen tube labelled with an anti-rhamnogalacturonan-II (a pectic motif) antibody developed by Matoh et al. (1998) using a microscope Leica DMI6000B equipped with a DFC450 C camera (FITC filter: absorption, 485-520 nm; emission, 520-560 nm wavelengths).
