| Research Abstract |
The aluminum (Al) tolerant mechanism in the two wild plants, Andropogon virginicus L and Miscanthus sinensis, were investigated. ABC transporter gene was isolated as an Al inducible genes from Andropogon. The gene was also response to oxidative stress and heavy metals. Other Andropogon genes which can confer multiple tolerance to various stresses were isolated. One of them was S-adenosyl methionine sysnthetase gene. Finally, we could isolate full length cDNA encoding these two genes from Andropogon.
