水稻螨虫mPing在自然条件下积极转座于‘金伯祖’品种基因组。在这项研究中，我们发现(1)mPing使相邻基因诱导胁迫，(2)mPing转位在Gimbozu中是遗传控制特异性的，(3)Rurm1的功能缺失等位基因有助于获得由于mPing转位而导致的遗传多样性。这些结果将为利用mPing技术开发高效转座子标记系统提供重要依据

Rice MITE, mPing is actively transposing in genome of cultivar ‘Gimbozu’ under natural conditions. In this study, we found that (1) mPing rendered adjacent genes stress inducible, (2) mPing transposition was genetically controlled specificin Gimbozu, and (3) a loss-of-function allele of Rurm1 was useful for acquiring the genetic diversity due to mPing transpositions. These results will greatly contribute to develop the high-efficiency transposon tagging system using mPing
