| Research Abstract |
In this study, we showed (1) the global gene and metabolite profiling of at the primordia and surrounding tissue of maize lateral root under osmotic stress conditions, (2) the characteristic of mutant in rice which reduced the emergence of the lateral roots and the crown roots, the isolation of the causal gene, and the analysis of that gene function, (3) the function of the metabolic enzymes of sugar for the root system formation, and (4) the root system formation and the distribution of the plant hormones in the transgenic plant for one of the tumor-inducing gene,6b gene, that regulated the function of auxin and cytokinin.
