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.

为了准确评价水稻对干旱胁迫的响应，修改了栽培方法。从经过干旱和湿润处理的植物中提取mRNA，并进行微阵列分析以评估干旱胁迫期间的差异表达。干旱有 83 个基因上调，151 个基因下调。与植物激素相关的基因在压力期间也会发生波动。尤其是与IAA代谢相关的基因明显波动。 IAA 可能是干旱条件下根系发育的重要第二信使。
