Analysis of heterosis caused by transposition burst of a transposon mPing in rice

研究了转座子mPing主动转座的细长颖壳突变体IM294的旺盛生长回复体中旺盛表型的分子机制。我们发现mPing的转座爆发对于旺盛表型的表达是必需的。此外，我们确定了20 mPing插入内或附近的基因在蓬勃发展的突变体VGI 1。这些结果表明转座子的转座爆发在生物进化中起着重要作用。

We investigated molecular mechanisms of vigorous phenotype in vigorous growing revertants of a slender glume mutant IM294 in which a transposon mPing is actively transposing. We found that transposition burst of mPing is necessary forthe expression of vigorous phenotype. Moreover, we identified 20 mPing insertions within or near gens in vigorous mutant VGI1. These results documented that transposition burst of transposon greatly contributes in evolution of organisms.
