Nucleic acid encoding GAI gene of arbidopsis thaliana

摘要

The GAI gene of Arabidopsis thaliana has been cloned, along with mutant and homologue gene sequences. Expression of such genes a plants affects characteristics of the plants including growth. GAI expression inhibits growth of plants, which inhibition is antagonized by gibberllin (GA). Expression of gai mutants confers a dwarf phenotype which is GA-insensitive. Manipulation of expression of GAI and gai genes in plants results in tall or dwarfed plants. Dwarf plants are useful in particular for reduction in crop losses resulting from lodging.
