The tapetal tissue is essential for the maintenance of redox homeostasis during microgametogenesis in tomato Open
SUMMARY The tapetum is a specialized layer of cells within the anther, adjacent to the sporogenous tissue. During its short life, it provides nutrients, molecules and materials to the pollen mother cells and microsporocytes, being essentia…

PsEND1 Is a Key Player in Pea Pollen Development Through the Modulation of Redox Homeostasis Open
Redox homeostasis has been linked to proper anther and pollen development. Accordingly, plant cells have developed several Reactive Oxygen Species (ROS)-scavenging mechanisms to maintain the redox balance. Hemopexins constitute one of thes…
