Allopolyploid and Its Utilization in Crop Genetic Improvement

所有的梨亚科是由两个远缘祖先类型双杂交演化的异源多倍体。

All the Pomoideae were allopolyploids derived from a doubled hybrid between two remote ancestral types .

经杂交后多倍化形成的异源多倍体植物，被认为在其形成的早期阶段经历了DNA序列消除过程。

Allopolyploids , resulted from combination of two or more differentiated genomes , have undergone DNA sequence elimination in the early stage after the formation of allopolyploids .

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 .

最近的研究表明，异源多倍体形成时常常伴有不符合孟德尔遗传规律的基因组变异发生。

Recent studies demonstrated that allopolyploid formation is often accompanied by genomic changes that cannot be readily explained by Mendelian genetic principles .

这类序列被认为在异源多倍体的建立和稳定中起着关键作用。

This class of sequences was proposed to play a critical role in the stabilization and establishment of nascent plant polyploids as new species .

不同分类群的异源多倍体在二倍化过程中，正反交序列消除往往表现出不同特征，暗示了在不同物种中，核质互作在多倍体进化过程的作用不同。

During diploidization , sequence elimination in reciprocal allopolyploids often appears variable in different species , suggesting that the nuclear-cytoplasmic interactions play different roles in different polyploid plants .

然而，人们对异源多倍体形成的早期阶段，来自不同物种的基因组共存于一个核一质中所必需的协调和变化尚不清楚。

Nevertheless , little is known regarding early events of coordination or changes that are required to ensure compatibility for the co-existence of two or more divergent genomes derived from different species in a single nucleus .
