  • Fig. 1 Pollen tube guidance in flowering plants.

    (A) Pollen tube guidance in Arabidopsis thaliana. Pollen tubes in the pistil were stained with aniline blue. Note the one-to-one guidance. Scale bar, 500 μm. [Image credit: M. M. Kanaoka, Nagoya University.] (B) A Torenia fournieri pollen tube attracted to LURE peptides (orange). The image in the bottom panel was acquired about 6 min after that in the top panel. Scale bar, 20 μm. [Image credit: Reproduced from (4).] (C) Long-distance attraction of T. fournieri pollen tubes to ovules in a microfluidic channel. Several pollen tubes originating from the top can be seen turning left, toward green ovules. Scale bar, 1 mm. [Image credit: Reproduced from (5).]
