非逆境条件下，IPT对秧苗根系中mRNA的表达差异与对照相比没有很大的变化；低温胁迫3天后，IPT对根系中mRNA的表达影响很大，既能增强某些基因的表达，又能抑制另一些基因的表达；用DDRT-PCR技术，寻找到5个低温胁迫下在对照和IPT处理中差异表达的基因，其中CY3片段与水稻CDPK1和CDPK2的mRNA有很高的同源性，初步断定CY3在植株的抗逆反应中可能具有与CDPKs相似的功能；在Genbank中没有检索到与其它4个片段同源性比较高的已知序列；IPT处理中CY3表达量在低温处理24hr就有明显升高，以后随胁迫时间的延长其表达量不断加强；恢复常温后，CY3表达继续增加，在恢复第14天开始下降，下降速度缓慢，IPT对CY3的影响一直延续到苗末期，对照中CY3在低温胁迫48hr才有微弱表达，72hr后表达量并未增加许多；恢复常温后第4天就开始下降，很快降到最低。
