Discussions are given of the fate of Ms2 during translocation in the hexoploid triticale, the exchange of the names for 4A and 4B chromosomes in common wheat and the possible expoitation of the new locus Ms2 (4BS), and the following speculations are made: In geneic genes of allopolyploid organisms the donor chromosomes tend to be intergenomically translocated to their phylogically and evolutionarily close chromosomes with the same order number and the same arm; it is cofirmed that the 7th International Conference of Wheat Genetics was right to exchange the names between chromosomes 4A and 4B of common wheat in 1988; and as a new genetic marker and a breeding tool for all the chromosome B-carrying species in the tribe of Tritceae, Ms2 (4BS) may have wide application in building and expanding the gene pool of germplasm resources of various species of wheat.
对 Ms2基因在六倍体小黑麦与原太谷核不育小麦远缘杂交中易位时的走向,普通小麦4A与4B染色体的互换更名以及 Ms2(4BS)新位点的开发利用进行了讨论:认为异源多倍体生物核基因的组间易位倾向于从供体染色体向进化亲缘关系较密切,且染色体序数与染色体臂相同的部分同源染色体易位;1988年第7届国际小麦遗传学会对普通小麦4A与4B染色体的互换更名是正确的; Ms2(4BS)作为一个新型的遗传标记,作为小麦族内所有携带B染色体组的物种的育种工具和在拓建各类小麦种质资源的基因库等方面均有广泛的用途。

This is a sound principle, though there may be rare exceptions: polyploidy in plants is common, and the symbiosis of micro-organisms that formed the eukaryota is a more exotic example.
这是一个合理的原则,但也可能有些罕见的例外:植物出现多倍体很常见,但微生物共生形成真核生物是一个比较奇特的例子。
