| Research Abstract |
Thermus cells produce the specific protein, a silica-induced protein(Sip), only when they are cultivated in the culture containing supersaturated silica. DNA microarray analysis under the silica-stressed and iron-deficient conditions were performed to detect the signal transduction in sip expression. From the results, Thermus cells may receive the signal of the existence of supersaturated silica as the iron deficiency, and may gather iron ions or other metal cations to their surfaces.
