水稻同源多倍体的研究策略

Strategy of the Research on Autopolyploid Rice

特异同源多倍体水稻自交后代的遗传研究

Genetic Study on the Self bred Progenies of Special Autopolyploid Rice

同源多倍体与其亲本二倍体在遗传上相隔离。

Autopolyploids are genetically isolated from their parental diploids .

以稻桩保存的同源多倍体自交结实种子为材料，研究了多倍体自交后代的一些遗传特征。

The seeds from the self-bred autopolyploid rice were used to study the characters of those progenies .

但目前关于同源多倍体表型、基因表达以及生理变化的机制还没有深入的研究。

But mechanisms of phenotypic , cellular , physiological and gene expression alterations in autopolyploid were still largely unknown .

结果表明：①同源多倍体自交后代大部分会保持其原来的倍性，但会有个别的变化；

The results show : ① Most progenies of self-bred autopolyploid still keep the original ploidy except a few progenies ;

同源联会异源多倍体这些相同的故事提示了众多他的流行祭礼的源头。

And many of the these same stories reveal the origins of the enormous popularity of his cult .

自然发生的同源三倍体水稻DNA甲基化与基因表达变化研究几乎没有，然而同源多倍体与水稻多倍体都与进化相关，因而同源多倍体与水稻多倍体基因表达与进化的研究也不应该被忽视。

Few researches were conducted on DNA methylation mutation and gene expression change of rice natural-genesic triploid . However , both of autopolyploid and rice polyploid are related to evolution , which should not be ignored in the research of polyploid evolution and gene expression .
