To date, alien introgression of agronomically important traits into bread wheat (Triticum aestivum) from wild relatives has not been readily achievable through traditional breeding practices. However, this door might now be unlocked. The insightful research published recently by Graham Moore and his team delivers a likely candidate in the form of a cdc2-kinase-related gene family for the Ph1 locus--a chromatin region located on chromosome 5B that is responsible for homologous chromosome pairing integrity in bread wheat.
迄今为止，通过传统育种方法，将具有重要农艺性状的外源基因从野生近缘种导入面包小麦（普通小麦）并非易事。然而，现在这扇门可能被打开了。格雷厄姆·摩尔及其团队最近发表的有深刻见解的研究提供了一个可能的候选基因，即一个与cdc2激酶相关的基因家族，该基因家族与Ph1位点有关——Ph1位点是位于5B染色体上的一个染色质区域，负责面包小麦中同源染色体配对的完整性。
