According to one source, a Planet was being pollinated with the Flower of Life by Zor's Battlefortress when it was attacked by the Invid. The ship was sent away remotely by Zor, who insisted on keeping his technology away from the war which was held between the Zentraedi and Invid. Zor apparently died on this planet, taking the secrets of Protoculture with him. (Robotech: The Graphic Novel)
