Cork oak microspore embryogenesis

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).This work has been supported by projects (BFU2011-23752, AGL2014-52028-R, AGL2017-82447-R) funded by the Spanish Ministry of Economy and Competitiveness, MINECO, and the European Regional Development Fund (ERDF/FEDER) of the European Commission.Peer reviewe
