从水稻中克隆了一个2型金属硫蛋白样基因OsMT-2（Oryza saliva metallothionein-like gene-2），并进行了序列测定。通过北方分析，OsMT-2的表达被示出在由蔗糖饥饿、热休克和在较小程度上的脱落酸引起的胁迫下被诱导，但不被过量的金属（包括铜）诱导。该基因对蔗糖饥饿的反应是短暂的，与铜诱导的水稻1型金属硫蛋白基因OsMT-1不同。这些结果表明，虽然OsMT-2也参与细胞对应激的反应，但其功能可能与OsMT-1的功能互补。
A type 2 metallothionein-like gene from rice, OsMT-2 (Oryza saliva metallothionein-like gene-2), was isolated in its cDNA form and sequenced. By northern analyses OsMT-2 expression was shown to be induced under stress by sucrose starvation, heat shock and, to a lesser extent, abscisic acid, but not excess metals, including copper. Its response to sucrose starvation was transient and different from OsMT-1, a type 1 metallothionein-like gene of rice inducible by copper. These results suggest that while OsMT-2 is also involved in cellular response to stress, its function may be complementary to that of OsMT-1.
