Characterization of a unique GATA family gene that responds to both light and cytokinin in Arabidopsis thaliana

Biosci Biotechnol Biochem. 2007 Jun;71(6):1557-60. doi: 10.1271/bbb.60692.


For higher plants, light is an important external signal, whereas cytokinin acts as an internal hormonal signal, and both are crucial for almost all aspects of development and physiological states. Here we identified and characterized a unique gene, CGA1, encoding a GATA factor, whose expression was rapidly induced by both the light and cytokinin signals in Arabidopsis thaliana.
