| Research Abstract |
Although rhizospheric microorganisms of acid-soil tolerant plants might play important roles in their adaptation to acid soils, their symbiotic tolerance mechanisms has been little known. To elucidate those mechanisms the draft genome sequences of such rhizospheric microorganisms were determined. Based on these draft genome sequences and other genome informations symbiotic interactions between plant hosts and rhizospheric microorganisms and those among rhizospheric microorganisms were studied. The structure and functions of extracellular polysaccharides produced by a symbiotic bacterium were determined, which suggested its roles in acid soil tolerance of the host plant. Significant differences in membrane lipids of Rhodotorula taiwanensis RS1 between cells grown in the presence and absence of aluminum ions were detected and the roles of such lipid in aluminum tolerance were examined.
