WebJun 1, 2004 · Pollination stimulates egg cell maturation in the maize ear [1].Thus, we investigated early post-pollination events in Zea mays to indicate putative elements of the signalling pathway. Pollen grain hydration, germination and pollen tube growth proceeded on the silk fragments in a humid chamber similarly as in planta.Cytoplasmic Ca 2+ level … WebCell signaling pathways begin when the ligand binds to a receptor, a protein that is embedded in the plasma membrane of the target cell or found in the cell cytoplasm. The receptors are very specific, and each ligand is recognized by a different one. This stage of the pathway is called reception. Molecules that are nonpolar, such as steroids ...
