Stress-Induced Microspore Embryogenesis by Anther Culture of Quercus suber L.
In vivo, the microspore inside the anther divides and follows the gametophytic program to form the mature pollen grain. In vitro, upon the application of a stress treatment the microspore can be deviated towards a proliferation process leading to embryogenesis, the so-called microspore embryogenesis that can be induced in anther and isolated microspore cultures (Maluszynski et al. 2003).
