EFFECTS OF HYGROMYCIN ON GROWTH AND DEVELOPMENT OF ARABIDOPSIS SEEDLING ROOTS
HONGYING DUAN* AND XIAOSHENG DING
Abstract
In this study, it was found that growth and development of Arabidopsis seedling main root and lateral root were affected by Hygromycin. Compared to the controls, main roots of Arabidopsis seedlings cultured on MS medium with Hygromycin were very short, and lateral roots were not formed. In addition, cells in the meristematic zone of root tip exhibited abnormal array, weak division ability, evident differentiation and large intercellular space. Accordingly, it is presumed that Hygromycin might influence growth of main root and formation of lateral root of Arabidopsis seedlings by restraining synthesis of some proteins.
