| Research Abstract |
The culture method was revised for evaluating the response of rice to drought stress precisely. mRNAs were extracted from plants treated with drought and wet, and subjected to microarray to evaluate the differential expression during drought stress. 83 genes were up-regulated and 151 genes were down regulated with drought. The genes related to phyto-hormones also fluctuated during the stress. Especially, genes related IAA metabolism were clearly fluctuating. IAA might be an important second messenger for root development under drought.
