| Research Abstract |
Short half-life period radio nuclei:^<11>C was introduced to the shoot as carbon dioxide by photosynthesis, then the distribution of ^<11>C to the rhizosphere was analyzed. It was demonstrated that the distribution was most pronounced to the rhizosphere very close to the area of lateral root. The analytical development of collection and analysis of root secreting low molecular compounds and high molecular compounds (proteins) were developed. Phylogenetical and functional analysis of microorganism from rhizosphere soil very close to the root was performed by using pyrosequencing method on microorganism DNA and the obtained result shows that some functional gene fluctuation may explain the difference of plant growth.
