| 摘 要： | 小麦育种的主要途径之一就是利用其近缘野生种的外源有益基因，但由于普通小麦５Ｂ染色体长臂上存在抑制部分同源染色体配对（Ｐｈ１）基因，使得在普通小麦的远缘杂交中外源有益基因不能通过易位方式直接转移到普通小麦中。若使Ｐｈ１基因发生突变或缺失，这种直接遗传转移外源有益基因即可成为现实。通过对Ｐｈ１基因的性质、作用机理及其突变体ｐｈ１ｂ基因的利用进行综述，最后提出Ｐｈ１基因的分子生物学研究方向。

| Abstract: | One of the ways of wheat breeding is using desirable alien genes transfered from distantly related species into wheat.But it is very difficult to direct transfer these alien genes into wheat by translocation because of the presence of Ph1 (Pairing homoeologous)gene that is located on the long arm of chromosome 5B in common wheat.This direct transfer method will be valuable if using the mutant that is deleted in Ph1 gene.The characters and interaction mechanisms of Ph1 gene and the usage of the mutant ph1b arose from a submicroscopic deletion in Ph1 gene are reviewed.The future outlook for the studies of molecular biology of Ph1 gene in wheat is also discussed. |
