Caged gene-inducer spatially and temporally controls gene expression and plant development in transgenic Arabidopsis plant

Two new types of caged gene-inducers, caged 17β-estradiol and caged dexamethazone, were synthesized. Caged gene-inducers were applied to transgenic Arabidopsis plants carrying a steroid hormone-inducible transactivation system. Light uncaged caged gene-inducers and controlled spatial and temporal expression of transgene in the transgenic plant. Furthermore, caged gene-inducers enabled the control of root development by light.
