Effects of antibiotics on root of Arabidopsis thaliana

In this article, it was found that growth and development of Arabidopsis thaliana seedling root were evidently affected by kanamycin and Hygromycin. Compared to the controls, main root of Arabidopsis thaliana seedling on MS with kanamycin or Hygromycin was very short, lateral root was not formed. In addition, cells in the meristematic zone of root tip exhibited abnormal array, weak division ability and large intercellular space. Therefore, it is presumed that kanamycin and Hygromycin might influence growth of main root and formation of lateral root of Arabidopsis seedlings by restraining synthesis of some proteins
