Abstract excerpt
The overly zinc sensitive Arabidopsis thaliana mutant ozs3 shows reduced growth of the primary root, which is exacerbated by an excess specifically of Zn ions. In addition, ozs3 plants display various subtle developmental phenotypes, such as longer petioles and early flowering. Also, ozs3 seedlings are completely but reversibly growth-arrested when shifted to 4°C. The causal mutation was mapped to a gene encoding...
