Researchers developed a two-photon microscope technique to observe pollen tube elongation in angiosperms. They discovered signals that attract and repel pollen tubes, ensuring one-to-one guidance for successful fertilization. This intricate regulation optimizes seed production, offering insights to enhance agricultural breeding practices by improving seed yield and germination rates.
