从水稻基因文库中筛选到一个与人类待定肿瘤抑制基因QM同源的基因,命名为OSQM2.该基因片断长为3.1kb,编码一个具有184个氨基酸的高度碱性的蛋白质.与其他已知QM基因相比,该基因具有一个非常特殊的启动子,包含许多在植物中已发现的与抗逆有关的顺式作用因子,如:"G盒","DRE盒","MYC盒"等,故而该基因有可能是一个新的受环境胁迫因子诱导的基因southern杂交表明它以单拷贝形式存在于基因组中.

A gene homologous to the human putative tumor suppressor gene QM was isolated from rice genomic li-brary. It was designated OSQM2. The sequence was about 3.1 kb long and encoded a highly basic protein of 184amino acids. It has a very special promoter region compared with other known QM genes. Many known cis-acting ele-ments such as "G box", "DRE" box, "MYC" box can be found in its promoter region, so it is a putative new stress-inducible gene. Southern hybridization indicated that it existed in rice genome as a single copy gene.
