Abstract

The Rht dwarfing genes of wheat have had a profound impact on the productivity of the modern `green revolution' wheat varieties that contain them. Genetic mapping experiments have shown that the Rht genes have a similar DNA sequence to that of the GAI gene of Arabidopsis. Here I propose to isolate the Rht genes by exploiting this DNA sequence similarity, to compare the gene DNA sequences of different Rht dwarfing alleles, to construct novel Rht alleles in vitro, and to transform these alleles into wheat, barley and rice. The aims are the further improvement of wheat productivity, and the transfer of an important method of yield enhancement to barley and rice.
