THE TRANSPORT PATHWAY OF LABELLED Mycena osmundicola AND ASSIMILATED LABELLED MATERIALS IN THE EMBRYONIC CELLS OF Gastrodia elata |
| |
| Abstract: | Mycena osmundicola Lange. was labelled by 3H|glucose and the seeds of Gastrodia elata B1. were sown on the saprophytic leaves of labelled M.osmundicola. By means of autoradiography, it is found that the labelled M.osmundicola infected embryonic cells of G. elata only through the suspensor cells. In the embryonic cells of G. elata the assimilated labelled materials entered into the cells by the wall of cell. After the protocorm formed, the assimilated labelled materials were transfered by the vascular tissue of G. elata. |
