ALA3 and PRKs are required for efficient pollen tube growth and guidance in the pistil. Left: Semi-in vivo pollen tube growth/AtLURE1.2-responsive assay of Col-0, ala3, prk3 prk6. Scale bars: 100 μm (top) and 10 μm (bottom). Right: Aniline blue staining of Col-0, ala3, and prk3 prk6 pollen tubes growing into Col-0 pistils. The asterisks mark ovules that did not attract nearby pollen tubes. Scale bar: 100 μm. Adapted from Yang et al. (2022), Figure 5.
