Abstract:

Gibberellins(GAs)are very important plant hormones that control diverse aspects of plant growth and development. Some important regulatory genes involved in gibberellin biosynthesis and signaling transduction pathway positively impact plant architecture,yield and quality of cereal crops,which has been applied in agricultural production. The alleles of Rht-1 and sd-1,that confer a semi-dwarf feature to wheat and rice,respectively,underpin the‘Green Revolution’in the latter half of the twentieth century. This paper reviewed the research achievements on the GA metabolism regulation in impacting the height,yield,nutrition usage of‘Geen Revolution’varieties,and prospected how to develop and utilize GA regulation genes for breeding more‘Green Revolution’varieties in the future.

Key words: gibberellins, Green Revolution, semi-dwarf, yield, metabolism regulation, biosynthesis, signaling transduction
