The guided journey of male gametes in flowering plants

At the heart of the Arabidopsis thaliana flower, the pistil, formed of hundreds of papillae and an ovary housing the ovules, is surrounded by stamens that release pollen grains carrying male gametes. In an article published in PLOS Computational Biology, scientists combine theory and experiments to reveal how male gametes are guided toward the ovules from the very beginning of their journey on the surface of the female reproductive organ.
