Studies on the Pairing Homoeologous(Ph1)Suppressor Gene in Common Wheat

doi:10.3321/j.issn:1000-7091.1997.01.008

Abstract

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.

Key words: Common wheat, Pairing homoeologous(Ph1)gene, Diretic genetic transfer, Molecular mark
